EDITOR'SDESK EPA Jurisdiction Questioned Have you ever wondered just how much authority the EPA actually has?
E
nvironmental rules and regulations are expected to be known by virtually everyone. Recent actions by EPA have demonstrated that it is actually the case. As residents of a small town in Idaho, Michael and Chantell Sackett purchased property in a developing subdivision. Although the property was a modest 0.63 acres, they still planned to build a home and a workshop on the site. A wetland was located adjacent to their property, while paved roads had previously been placed in the front and back of the site. In addition, another home had already been built on the other side of the property. Prior to building their new home, the Sacketts exercised normal due diligence and obtained permits to construct from the local authorities. Since they wanted to level the property, a contractor began to prepare the land after the couple received their permits. In the meantime, it appears that someone unknown to the couple complained. The person’s identity was protected against disclosure. The EPA showed up at the property and noted the contractor adding fill material to the site and ordered them to cease all activity because the agency considered the property to be a wetland. According to documents that the property owners sent to the Army Corps of Engineers, the Shaketts asked the EPA representative how they could determine the property was a wetland; in response, the EPA representative stated that a “little water was visible.” The couple had sold their home before the housing bubble burst and they were living in temporary quarters until construction was completed. They tried to contact the EPA to see what could be worked out. They were rebuffed. So, they took the only recourse left to them by filing a lawsuit. EPA filed a motion to dismiss and the judge granted it. When their lawyer filed for clarification and reconsideration, the judge again denied their request, concluding that his decision did not require clarification. The couple met with legal walls at every turn. EPA sent a letter to the Sacketts demanding that they restore the property to its original condition. Further, they told the couple that penalties for failure to comply could cost them as much as $37,500 per day. The order further described in some detail the quantity and types of plants that must be placed – and where. They were also told to monitor the site to ensure that the plants had survived. EPA demanded full access to the property and required
the couple to disclose the agency documents to any future potential purchaser. The maze of legal twists and turns seem unimaginable. Reading some of the Ninth Circuit Court decisions seemed like watching the movie, Catch 22. What is a private citizen or even a small business to do? Fortunately, the wetland topic has never been completely addressed by the courts and some corporations thought this might be a good opportunity to obtain a ruling from the best legal minds in the land. On Monday, Jan. 9, 2012, lawyers presented arguments to the Supreme Court justices. Several corporate interests have joined the process to add their
“
The Sacketts should have received a helping hand from the EPA rather than being treated so poorly.
voices by filing friend-of-the-court briefs for the case. The wetland topic is one that is particularly difficult for even the most seasoned environmental professional, let alone a private landowner. In the past decade, arguments have progressed to the highest court in the land where the final decision was that the Army Corps of Engineers and EPA have overreached their authority in deciding what constitutes a wetland and navigable waters of the United States. I, for one, hope that the justices will make a clear declaration that will finally put this issue to bed and help corporations make better decisions. I also hope they find a way to help protect private citizens from what appears to be overzealous actions by government agents. The Sacketts should have received a helping hand from the EPA rather than being treated so poorly. If the property is a wetland, then there should have been a way to provide offsets or some other mechanism to help, rather than just slap the couple around and effectively confiscate their property.

EPOCH™
Compliance Tracking Software is First GHG Data Reports Available The first comprehensive greenhouse gas (GHG) data reports from large facilities and suppliers in the United States are accessible to the public through the EPA's GHG Reporting Program. The data is from 2010 and includes statistics from nine industry groups, as well as suppliers of certain fossil fuels. EPA’s online data publication tool allows users to view and sort GHG data for calendar year 2010 from over 6,700 facilities in a variety of ways—including by facility, location, industrial sector, and the type of GHG emitted. This information can be used by communities to identify nearby sources of GHGs, help businesses compare and track emissions, and provide information to state and local governments. GHG data for direct emitters show that in 2010: • Power plants were the largest stationary sources of direct emissions with 2,324 million metric tons of carbon dioxide equivalent (mmtCO2e), followed by petroleum refineries with emissions of 183 mmtCO2e.

ENVIRONEWS Engineers are now Scientists The American Academy of Environmental Engineers announced the organization is changing its name to the American Academy of Environmental Engineers and Scientists. Additionally, the organization announced a new certification program, which will be offered by the group. The new certification is called Board Certified Environmental Scientist. “The academy has been certifying environmental engineers since 1955. We are truly excited to offer this parallel certification for environmental scientists,” said Brian P. Flynn, president of AAEE. “Most significant environmental projects involve interdisciplinary teams of environmental engineers and environmental scientists. The certification of environmental scientists provides assurance to employers and the public that those professionals have demonstrated a high level of competency in their practice, just like certified environmental engineers.”
“This new certification program effectively aligns the Academy with its members and their employers. Our name change underscores the critical dependencies between Environmental Engineers and Environmental Scientists. We are looking forward to some very exciting programs and projects in the near future,” Flynn added. The Academy anticipates taking applications for Environmental Scientists beginning March 31, 2012, and administering the first set of examinations in 2013. The name change will be officially implemented in the near future. For more information, visit www.aaee.net.

ENFORCEME ENT Midwest Miner to Clean Indiana Triad Mining Inc., a subsidiary of the Janes River Coal Co., owns and operates 31 surface mines in Appalachia and Indiana. The company has reached an agreement with the EPA and the DOJ that will require the operation to pay a $810,171 civil penalty and restore 34,906 linear feet of streams and enhance 4,330 linear feet of stream bed to address and mitigate impacts to the beds that were caused by its mining operations. Triad will also create and maintain 66 acres of forested buffer areas and nine acres of forested wetland to protect the restored streams. Since 2002, Triad’s mining operation has resulted in the unpermitted excavation and filling of more than 53,000 feet of streams that flow into the White River. On March 24, 2008, the Army Corps of Engineers issued a cease and desist order that required
ENVIRONEWS the company to stop its unauthorized streamfilling activities. However, the mining practices continued until the Army Corps of Engineers sent a second order on June 24, 2009, and the company complied. Since the second order was issued, the mining operation has continued mining, but has avoided additional impacts to streams.

and zinc into Redwood Creek, a tributary flowing into the San Francisco Bay. Such discharges are a direct violation of the federally mandated Clean Water Act. As a result, the organization was ordered to update its toxic pollutant monitoring and sampling capabilities by January 20, 2012. The organization must also create and submit a plan to the EPA regarding the methods employed to eliminate illegal discharges in the future. The EPA must receive the plan by March 20, 2012. “The EPA is committed to protecting the Bay by ensuring compliance with environmental permits,” said Jared Blumenfeld, the EPA's regional administrator for the Pacific Southwest. “Companies such as Sims Metal Management, engaged in recycling our finite resources, must abide by the Clean Water Act.” For more information, please visit http://yosemite.epa.gov/opa/admpress. nsf/0/585E7BC1BF86C1CD85257980007 1A3CA or use a smartphone with the Microsoft tag.
Cool Little was known about a biradical named Criegee until recently. However, this little molecule may be the answer to cooling the atmosphere more efficiently that science had thought.
WASTE Huge California Recycler Ordered to Shut Down The EPA recently ordered the world’s largest metals and electronics recycler, based at the Port of Redwood City, Calif., to end its illegal discharge of toxic pollutants into the San Francisco Bay – and without any delay. The organization, known as Sims Metal Management, was inspected last year by the EPA and the agency found that the company had been discharging illegal amounts of copper, lead, mercury, PCBs
Named after a German chemist named Rudolf Criegee, the biradical is created in the Earth’s atmosphere when ozone reacts with alkenes. The compound is short lived but had the ability to produce aerosols that reflect solar radiation back into space much more quickly that previously assumed.
Just recently, researchers were able to reproduce these particles in the lab for a more comprehensive study. The existence of these particles has been known for decades. The alkenes are produced by the Earth’s ecosystems. According to Carl Percival, an atmospheric chemist at the University of Manchester in the United Kingdom and co-author of the study, “the ecosystem is negating climate change more efficiently than we thought it was.”
2010 TRI Data Released The EPA has just released its 2010 Toxics Release Inventory (TRI) national analysis, which provides information to the general public in regards to toxic chemical disposals, as well as pollutants that have been emitted into the nation’s air, land and water resources. The analysis has found that 3.93 billion pounds of toxic chemicals were released into the environment in 2010 – a 16 percent increase in comparison to 2009 data. However, the analysis also revealed that toxic releases were still lower in 2010 than they had been in 2007, as well as other prior years. In addition, according to past analysis, total air releases have declined by six percent since 2009, while releases into surface water and land have risen by nine and 28 percent, respectively, since 2009. “We will continue to put accessible, meaningful information in the hands of the American people. Widespread public access to environmental information is fundamental to the work EPA does every day,” said Lisa P. Jackson, EPA administrator. “TRI is a cornerstone of EPA’s community-right-to-know programs and has played a significant role in protecting people's health and the environment by providing communities with valuable information on toxic chemical releases.” For more information regarding the 2010 TRI national analysis, please visit http:// yosemite.epa.gov/opa/admpress.nsf/0/ A64903C5C1540CF38525797C0064E3F5 or use a smartphone with the Microsoft tag.

ENVIRONEWS WATER EPA Starts Water Quality Workshops The EPA has announced that it will host a variety of workshops regarding municipal stormwater plans and the Clean Water Act's objectives for higher water quality in the future. Through the workshops, the EPA will hopefully be able to create a planning approach framework that can assist municipalities as they strive to utilize their infrastructure assets in a more sustainable manner, which will ultimately help the agency improve the quality of the country's water resources. During the workshops, representatives of various organizations will be able to discuss future municipal stormwater and wastewater plans regarding the Clean Water Act. Members of the public may also participate in the workshops as observers,

Greening Brownsville Lisa P. Jackson EPA administrator, recently traveled to Miami to meet with local green business leaders and tour the Brownsville Transit Village, a new environmentally sustainable building project in an underserved community that incorporates water and energy-saving features. The project, set to open in March, is being developed by the Carlisle
Development Group, which creates environmentally sustainable affordable housing. The group is working in partnership with Alterna Corp., an EPA WaterSense partner and distributor of green building products. Estimated water savings of Brownsville Transit Village are over 5 million gallons per year and roughly $50,000 per year in utility savings (i.e., compared to standard plumbing fixtures). EPA’s WaterSense initiative brings together local water utilities, governments, product manufacturers, and retailers to promote water efficiency, and enhance the market through innovation and product design for water efficient products, programs, and practices. The EPA and its WaterSense partners have helped Americans save 125 billion gallons of water and more than $2 billion in water and energy bills. By reducing water consumption, the program has reduced 6 million metric tons of CO2 emissions, protecting the health of Americans.

ENVIRONEWS Environmental Justice Grants The EPA has announced four environmental justice grants totaling $100,000 that will go to non-profit and tribal organizations in the Great Lakes region. Projects in Minnesota, Indiana, Ohio and Wisconsin will get help to conduct research, provide education and develop solutions to health and environmental issues in communities that are overburdened by pollution. Environmental justice is the principle of achieving the same degree of protection from environmental and health hazards for all people, regardless of race, color, national origin or income. The projects that were approved are: • Red Lake Band of Ojibwe Indians, Beltrami, Minnesota: Improve wells and septic systems on the Red Lake Reservation by assisting in repairs of failing systems and educating tribal members about proper maintenance. Failing septic systems are a public health threat due to nitrogen, phosphorous and bacteria affecting surface water, ground water and well water. Partners in this project include the Natural Resources Conservation Service, Indian Health Service, Red Lake Housing Authority and the University of Minnesota. • Improving Kids Environment, Indianapolis, Indiana: Analyze lead levels in soil in the Martindale-Brightwood community, identify airborne particulate hot spots in the Near Westside community and use the combined data to educate people and protect children from lead poisoning. Partners include the Martindale-Brightwood Environmental Justice Collaborative, Indiana University Center for Urban Health and Earth Sciences Department, and Westside Cooperative Organization. • Cleveland Tenants Organization, Cleveland, Ohio: Prevent and treat issues with bed bug infestations. CTO will educate landlords, property managers and tenants in subsidized multi-unit family housing developments about how to prevent bed bug infestations and reduce the misuse of pesticides. Partners include Environmental Health Watch, Cleveland Department of Public Health and the
U.S. Department of Housing and Urban Development’s Cleveland Office. • Social Development Commission, Milwaukee, Wisconsin: Reduce the risks to children of lead exposure through education and by helping low-income families assess their homes and abate lead dangers. Partners include the
city of Milwaukee Health Department, Sixteenth Street Community Health Center and Wisconsin Childhood Lead Poisoning Prevention Program. The EPA also announced it is seeking applicants for $1 million in environmental justice small grants expected to be awarded in 2012.

LEGALLOOKOUT By Lynn L. Bergeson
Nanosilver Conditionally Registered as New Active Ingredient What impact will HeiQ AGS-20, a nanosilver-silca composite, have on the future well-being of humans – and the environment? n August 2010, EPA announced that it was considering allowing the Swiss company HeiQ Materials Ag to enter the U.S. market with a new nanosilver pesticide and textile preservative, HeiQ AGS-20. On Dec. 1, 2011, the EPA issued a conditional registration for a pesticide product..
I
The Product TAGS-20 is a nanosilver-silica composite where the nanosilver is sintered onto amorphous SiO2, with typical particle diameters of one micrometer (1,000 nanometers). EPA’s risk assessment relied on the existing reregistration decision for silver and concluded that the human health or ecological risk from exposure to silver ions Link to the derived from AGS-20 treated texDiscussion tiles is not of concern. For purGuide. poses of risk from exposure to AGS-20, the manufacturer submitted results from short-term acute animal toxicity tests completed using high-level doses of AGS-20. No major issues were identified. According to EPA’s Decision Document, AGS-20 caused moderate to no irritation to the skin and eyes of test animals, but was not a skin sensitizer. Based on these results, EPA will require shipping containers filled with AGS-20 to use the DOT "CAUTION" label. EPA used conservative assumptions that overestimate the dose of nanosilver that could potentially be derived from AGS-20, along with maximum values for risk uncertainty factors. It determined that, for the period of conditional registration, there is a low probability of adverse risk to children and the environment. Thus, the agency concluded that use of AGS-20 will not cause unreasonable adverse effects on the environment during the period when newly required data is being developed. The agency notes that it does have a risk concern for occupational exposure when handling AGS-20 powder during mixing and loading operations. As a condition of registration, EPA is requiring HeiQ to conduct many studies during the period of conditional registration. The required tests include route-specific toxicity studies for occupational exposure scenarios, as well as product characterization and stability tests to
determine if nanosilver breaks away from AGS-20. EPA states that, if nanosilver is found to break away, then additional testing will be triggered to determine the effect that nanosilver has on humans and the environment. These studies must be completed within four years, since EPA chose to allow time for protocol reviews prior to initiation of the studies, completion of the studies and its review of the study results. The data requirements are set forth in Appendix A of the Decision Document. The studies listed in Table 1A are considered Tier I because their need is not based on the results of any other studies. Tier II studies may or may not be required based on the results of the Tier I studies. EPA intends to evaluate the data to confirm that the use of AGS-20 will not cause unreasonable adverse effects to human health and the environment. If the manufacturer fails to take appropriate steps to initiate the required studies, or they fail to submit the protocols or data, EPA will issue a notice of intent to cancel the registration under FIFRA Section 6(e).
Discussion EPA’s approval of the HeiQ nanopesticide product is a big deal. EPA’s determination that the use of AGS-20 is in the public interest is very promising. EPA states that it may lead to less environmental loading of silver as compared to currently registered products with the same use patterns. Importantly, EPA notes AGS-20 appears to offer prolonged ability to suppress the growth of odor causing bacteria through the slow release of silver ions, in comparison to the rapid release of silver ions from registered products containing silver salts. EPA’s Decision Document is available at www.regulations.gov/#!documentDetail;D=EPAHQ-OPP-2009-1012-0064 or use the tag with a smartphone. PE

2011 Capital Expenditure Study With uncertain economic conditions, we wanted to learn what our audience thought about environmental spending.
By CHRIS LEWIS n recent years, the ebbs and flows of the global economy have undoubtedly impacted the business operations of thousands of worldwide pollution control and w environmental organizations. As a result, a majority of organizations have had no choice but to lay off hundreds, if not thousands, of loyal employees just to stay afloat. Many organizations have also significantly reduced their budgets and cut back expenses in order to operate on a large-scale basis in the future. But has the pollution control industry’s capital expenditures been reduced lately, especially regarding the purchase of equipment and services? Will such spending change at all in the near future? Also, what are some of the most likely capital expenditure trends – and what motivates organizations to purchase some goods and services rather than others? To answer such questions, Pollution Engineering recently conducted a comprehensive survey, entitled Pollution Engineering’s 2011 Capital Expenditure Study, to identify environmental capital expenditure trends within the pollution control industry. Overall, 9,489 Pollution Engineering subscribers were contacted from Oct. 26 through Nov. 9, 2011. Of the survey respondents, 43 percent were working as consultants, 36 percent were employed in manufacturing and 21 percent either worked in utilities or for governmental organizations. Here are some of the more salient points that were discerned by our staff.

As pollution control organizations prepare for the future and continue to work towards the path of economic recovery, survey respondents shared their thoughts regarding their organizations’ pending strategies for 2012. All respondents revealed that their companies are primarily focused on achieving the following six objectives this year: • Improving business efficiency • Maintaining existing business operations • Increasing capacity • Improving organizational sustainability • Building new facilities • Reducing labor expenses However, depending on each survey respondent’s particular industry, some organizations are more focused on achieving particular goals over others. According to survey results, consultants’ organizations are especially determined to utilize their capital expenditures while improving efficiency (55 percent), maintaining their business operations (43 percent), increasing their capacity (39 percent), developing new facilities (35 percent) and improving sustainability (32 percent). Yet, for manufacturers, some of these objectives are not quite as important to them as they are to consultants. Sixty-three percent of all manufacturers consider the improvement of efficiency as a prime reason for their organizations’ capital expenditures in 2012. At the same time, manufacturers’ organizations will also likely spend their expenditures on the maintenance of business operations (60 percent), the improvement of capacity (43 percent) and sustainability (38 percent) and the reduction of labor expenses (21 percent). Finally, like manufacturers, employees that either work in utilities or for governmental organizations believe their organizations will be primarily focused on maintaining their operations (61 percent) and improving efficiency (47 percent). Thirty-nine percent of respondents stated their organizations will increase capacity, while 36 percent believe their employers

budgets would likely be reduced. See Figure 5. Looking ahead even further, the government sector remained the most pessimistic, while consultants and manufacturers were much more upbeat. In all cases, over half of the respondents replied that they
Meanwhile, survey respondents also revealed what percentage of their organizations’ budgets were used towards the acquisition of equipment, services and/ or technology in 2011. Again, each of these figures tended to vary according to the types of positions respondents held, as well as their particular employers’ industries of focus. See Figure 1. The data indicated that government entities tended to spend less of their total budgets on these services. On the other hand, consulting and manufacturing sectors spent significantly more as a percentage. 2012 equipment, services and technology purchases In the meantime, it appears consulting organizations expect their expenditures will slightly decline in 2012 compared to 2011. Still, manufacturing and utilities organizations, as well as government institutions, will roughly spend the same amount in 2012 as they did last year. See Figure 2. Nevertheless, the data also appears to show that some manufacturing operations are expecting to increase their equipment budgets throughout 2012, especially as the economy strengthens
2012 vs. 2011 capital expenditure budget It appears that a majority of respondents have a bright outlook for 2012. In all sectors, more than half of the responses stated that their organizations fully expected budget increases throughout the duration of the new year. See Figure 3. All respondents who stated their organizations’ budgets would increase from 2011 to 2012 were asked to provide further information regarding their expenditures. While government operations remained the least optimistic, some sectors still anticipate an increase in their organizations’ budgets, sooner rather

Which purchasing factors are the most significant? Consulting – To further determine exactly why pollution control organizations were either increasing or decreasing their capital expenditures, the survey also asked all respondents what purchasing factors mattered the most to them and to their employers. Consulting engineers, who comprise 62 percent of Pollution Engineering’s subscribers (more than any other environmental magazine), tended to believe that quality was the single most important factor in making purchasing decisions. In addition, price, total cost of ownership and the ability to contribute to operational efficiency were also viewed as significant purchasing factors. See Figure 6. Manufacturing – All manufacturing respondents also offered information regarding the factors that are generally imperative to their purchasing decisions. Again, we see that overall product quality 26

was the largest purchasing factor. Notice that, at this point, there was a divergence from the consulting group. Consultants believe that contribution to efficiency, customer support, price and total cost of ownership are also imperative purchasing factors. See Figure 8. Utilities/Government – Lastly, respondents from the utilities group shared the opinions of the other groups in regards to the idea that product quality was the most important purchasing factor. This factor was then followed by price, ease of maintenance, contribution to operational efficiency and total cost of ownership, in order of apparent significance. See Figure 7.
2012 purchasing plans Finally, the Pollution Engineering’s 2011 Capital Expenditure Study sought to discover the types of equipment, services or technology the subscribers will likely purchase in 2012, as a result of their capital expenditure budgets. Overall, we listed 15 categories; according to survey results, it appears subscribers will most likely purchase consulting services, pumps, pipes and valves systems, air pol-
lution control, water pollution control, software and hazardous waste control systems throughout 2012.
Conclusion According to the study, many survey respondents’ organizational budgets are expected to increase in 2012, in comparison to 2011. Forty-nine percent of manufacturers and 46 percent of consultants believe their organizations’ budgets will expand throughout 2012. Although such figures were much lower regarding survey respondents that work in utilities or for government-controlled organizations, a majority of respondents still believe their companies will spend between one and 60 percent of their budgets on the purchase of equipment, services, and technology this year. As organizational budgets continue to increase in 2012, there is little doubt the environmental spending of Pollution Engineering subscribers will also rise. And, participants believe that trend will continue into the next year. Expect those plans to be built during the coming year. PE
Continuous
STACK Monitoring with
GC-FID
By PETER FROEHLICH, President, Peak Media, and Judy Silva, Manager Technical Publications, Parker Hannifin Corp. Figure 1: Above is a photograph of the Parker Balston Model 75-82-S explosion proof zero gas generator
What exactly are the benefits to operating an explosion proof onsite zero air generator, rather than gas cylinders? as emitted from an industrial facility smokestack, such as a power plant, refinery or chemical plant, contain a variety of gases, including H2O, CO2 and CO, various nitrogen oxides and a mixture of organic compounds at trace levels. As an example, a number of polycyclic aromatic hydrocarbons (PAHs) and complex heterocyclic compounds may be emitted by a power plant that burns coal or fuel oil due to the incomplete combustion of the fuel. Because many of these compounds are carcinogenic, mutagenic or teragenic, their emission is closely regulated by governmental agencies and plant operators are required to continuously monitor the stack gas emissions. Monitoring stack gases for trace levels of organic compounds is typically performed by process gas chromatography with flame ionization detection (GC-FID) in order to determine the level of hazardous gases that
G
are emitted into the environment. An FID combusts the compounds that elute form the GC to form ions, which are then detected by an electrometer. The FID requires air that is free of organic compounds (zero air) to optimize the sensitivity of the analysis. While atmospheric air contains a sufficient concentration of oxygen to support combustion of the compounds in the FID, trace levels of organic compounds in the atmosphere will lead to a high background signal, which will reduce the sensitivity of the detector. To optimize the sensitivity and meet monitoring requirements, an FID typically uses zero air to set the minimum reading. Zero air contains less than 0.1 ppm of hydrocarbons. While zero air is commercially available in gas cylinders, an explosion proof onsite
zero air generator provides a safer, more convenient and cost effective approach to supply the requisite gas. In this article, we will describe the operation of an explosion proof onsite zero air generator and outline the benefits of this approach instead of the use of gas cylinders.
Generating zero air onsite Generating zero air for a GC-FID involves removing particulate matter and combustible compounds, such as hydrocarbons and other organic compounds from atmospheric air. A GC-FID system to monitor stack gases requires a high flow rate. The gas must be available on a 24 hour, seven day a week basis to continuously monitor the com-

position of the stack gas, in contrast to an analytical GC-FID system that is normally used on a periodic basis. An on-site zero air generator (Figure 1) removes the organic compounds from clean, dry compressed air (inlet pressure 40 to 125 psig with a pressure drop of 8 psig) with a maximum flow rate of 1,000 cc/min, which is more than sufficient for an FID. A cutaway view of a typical explosion proof zero air generator is presented in Figure 2.The compressed atmospheric air is first passed through a particulate filter in the generator to remove particles that are greater than 0.5 microns and then passed through a heated chamber that contains a specially designed catalyst to convert organic compounds in the air into CO2 and H2O. These compounds will not lead to a signal from the FID. While the catalyst module is capable of converting a broad range of organic compounds into CO2 and H2O, it should be noted that high concentrations of organolead, organosulfur or organophosphorous compounds, heavy metals, chlorinated hydrocarbons, chlorofluorocarbons and long-chain polymers in the atmosphere may tend to reduce its efficiency over time.
The benefits of on-site zero air generation Commercially obtained compressed air tanks are used to supply zero air to the FID in many facilities. While tanks can provide 28

gas, they can introduce other safety and cost related issues and require continual monitoring to ensure that sufficient gas is available. In contrast, using an on-site zero air generator can provide a safer, more convenient and cost-effective approach to supply the gas to the detector. In addition, the use of an on-site generator reduces the environmental impact of supplying the gas. a) Safety – The use of an-site generator completely eliminates the need to handle pressurized zero air gas cylinders. In many facilities, gas cylinders are stored in a remote area and are transported to the location of the process GC when needed, which can be quite an inconvenience in inclement weather. If the individual moving the tank loses control of it, significant damage could occur to property and or individuals. In the same vein, if the valve becomes defective, the tank may become a guided missile, as the internal pressure of a full tank is more than 2,000 psi. To minimize these concerns, many facilities use specially trained technicians to replace gas tanks. b) Increased convenience – An onsite zero air generator is designed to supply zero gas on a 24 hour, seven day a week basis without any user interaction, thereby allowing the operator to maintain the usage of detector at all times. In contrast, if tanks are used, the operator must ensure that sufficient gas remains at all times and many facilities supply gas to the detec-
tor only when an analysis is performed to minimize the gas consumption. If a tank is used and the need for replacement occurs during a series of analyses, the operator may have to interrupt the analytical work to restart the system and wait for a stable baseline. In addition, if a process is continually monitored, the analyst must ensure that sufficient volume of gas is available before the sequence begins. Since many organizations store gas tanks outdoors, the acquirement of a new tank may be inconvenient in inclement weather. Although the onsite generator typically requires little maintenance, the final filter cartridge and the catalyst should be replaced at least every two years. c) Lower operating cost – In addition to significant safety and convenience benefits, another advantage of an onsite generator is the economic benefit compared to the use of gas tanks. The running cost of the zero air generator is low, as it merely requires a source of compressed air and has an electrical requirement of 0.5 A. If the generator is used on a 24-hour basis, the energy required would be less than 2 KW/day; if the cost of electricity is $0.10/kwh, the daily cost is $0.20. Maintenance cost is low, as the only components to be replaced are the final filter cartridge and the catalyst, which is typically replaced every two years. d) Environmental benefits – The energy requirements for a zero gas generator is quite low. In contrast, when tanks are employed, the zero gas must be purified and compressed to 2,000 psi. Once the tanks are prepared, they must be transported to the end user’s site while the empty tanks are returned to the supplier. While the amount of energy that is required for transportation of the tanks depends on the distance between the end user and the supplier, it is clear that a significant amount of energy is expended in the movement of tanks, thereby generating greenhouse gases and contributing to the overall environmental concerns.

An in-house zero air generator provides the ability to monitor the stack gas on a continuous basis without the need for frequent operator attention.
Conclusions Trace levels of complex organic compounds, including polycyclic aromatic hydrocarbons (PAHs), are emitted by a power plant that burns coal or fuel oil due to the incomplete combustion of the fuel. Since many PAHs are carcinogenic, mutagenic or teragenic, their emissions are closely regulated by governmental agencies.

must be designed to meet stringent safety considerations. The zero air generator should be housed in an explosion proof enclosure to operate in Class 1, Groups B, C and D environments. An in-house zero air generator provides the ability to monitor the stack gas on a continuous basis without the need for frequent operator attention. The in house generator provides a number of significant benefits relative to the use of compressed gas tanks including an increase in safety, greater convenience and a lower cost. The generator also eliminates the need to transport tanks, lowering the environmental impact of the overall process. The zero air generator can be used to provide fuel for any process instrument that measures hydrocarbons. PE Peter Froehlich is the president of Peak Media, Franklin, Mass. He can be reached at

After the process has been defined and a preliminary equipment choice has been determined, the next step is the identification of potential vendors.

The product line should be complete, allowing for different options should the process conditions warrant. The company should have a reputation for thinking outside the

box and the ability to respond quickly and effectively to customers’ needs. A reasonable amount of market share, measured by number of installations and the quality of the existing customers, is a good arbiter of the company’s performance in its market. In today’s tough economic climate, any vendor should be assessed for various financial conditions. Bigger is not always better. A variety of tools can be used, such as Dun and Bradstreet Reports, references for vendors to the supplier, and the supplier’s ability to obtain a performance bond, among others. A well run supplier typically maintains a competitive pricing position. Finally, in today’s fast-paced marketplace, you should not necessarily accept a company that offers a one size fits all or standard system if it does not fit a particular process. A flexible supplier will work with the customer to maximize production and quality while also minimizing operating and maintenance costs.
The project management team A typical capital project can have a timeline of anywhere from six months to two or three years between inception and commissioning. The project teams and their leaders should be identified for both the supplier and the customer. The supplier’s team typically will include the project manager, design engineer(s) and a sales manager. The customer's teams should include the key decision maker, relevant technical and regulatory personnel and purchasing. Because of the length of time to complete a capital project, it is important to have multiple individuals on both teams cross qualified during the process in order to step in when needed, especially if a key project team member is not available. A common gap in the acquisition of capital equipment systems can occur between the technical team and purchasing; this often happens late in the process, which negatively impacts the project schedule. Because of this, purchasing should be involved early and in accordance with the customer’s purchasing policies. An effective team will assure that the best technical option is purchased in an effective manner.
With proper preparation, good communication and teamwork, the final result will please everyone involved.
Initiating the purchasing process The selection of suppliers is typically determined through a preliminary budget proposal process. Any confidentiality or nondisclosure agreements should be completed at the earliest possible date. Responding to a basic process description, a quality vendor will use their experience to develop a proposal, including operating costs. Depending on the information available, this step can occur either before or after a supplier's first visit to the facility. If the reliance on the vendor for technical information is critical, then a site visit prior to completing a proposal is a prudent measure. Proposals should be as technically complete as pos-
sible and have a reasonable accuracy in pricing, which allows the customer to assess the supplier’s capabilities in greater detail. In fairness to the vendors and to acquire effective information, the process description/RFQ should be consistent and clearly identified as preliminary.
Ensuring an effective site visit In today’s manufacturing environment, no one has excess time available. A few basic steps will enhance the supplier’s on-site activities. A clear meeting agenda with specific timelines and discussion topics can be independently developed by either party or, better yet, on a collaborative basis. Prior to

arrival, any site-specific training and equipment requirements (safety, etc.) should be identified and accounted for in the agenda. Photos are an important tool in developing the project as well. To recognize security requirements and the need to protect proprietary information, a photo policy should be confirmed prior to any visit. Depending on the process and system being specified, as well as its primary focus, the meeting should be scheduled at an optimum process time, whether shutdown or operating under normal operating conditions. A reasonable amount of time to assess the process should be allowed, followed by a closeout meeting. In addition, the development and review of an action list is quite critical; scheduling multiple suppliers at the same time should be avoided. Suppliers can be wary of asking pertinent questions in front of competitors, thus stifling proper information development. Often the equipment system is only part of the challenge as the installation and integration of the equipment, especially in a currently operating facility, can present challenges as well. Any copies of 32
Pollution Engineering FEBRUARY2012
non-confidential facility or utility layouts, drawings or photos that are relevant to the installation should be provided to the supplier as early as feasible. Available space, existing utilities and ongoing operations should be carefully assessed. Utility capabilities and locations should be reviewed to ensure the supplies are adequate including gas pressure, available voltage, water pressure (and quality) and plant compressed air. Any requirement for dedicated systems (such as stand-alone compressors) and protective systems (isolation transformers, etc) should be reviewed. Process by-products are an important element and should be assessed during the site visit as well. Any emissions or byproducts create another potential handling issue. The facility’s available wastewater capacity is often a critical issue for equipment that require large amounts of water.
Managing the supplier When the time for final vendor selection or equipment purchase nears, the two teams should meet on a professional, yet personal, basis. A meal or team building exercise helps
develop the personal working relationships critical to a long-term project. An effective flow of information will help the supplier and the project succeed. Also, during large capital projects, there is often a continuous cycle of process development that can mandate changes in the scope of supply; this is another reason why solid communications between the teams is vital. Key points of contact should be established and questions and queries promptly answered by both parties. Capital equipment suppliers effectively manage multiple projects. Oftentimes this provides an opportunity for cost reduction through the supplier’s vendors and through fabrication economies of scale. A key business component in the capital purchasing process is the Terms and Conditions (T&Cs) section of the contract. T&Cs are in place to protect both parties. A customer attempting to place onerous T&Cs, especially later in the process, runs the risk of placing the supplier on the defensive. Typically, this does not enhance the technical aspects of the system, but rather serves to artificially increase the costs. Any effective business
TEAMING with a
QUALITY VENDOR
transaction between the teams should be fair to both parties. All questions or concerns with T&Cs should be identified, discussed and resolved as early as possible.
fabric structures
From final proposal to the purchase of equipment The next to last milestone in the process is the development of a comprehensive equipment specification/Request for Proposal (RFP). The RFP should contain an accurate description of the process conditions, expected performance and the anticipated project schedule. Utility costs are essential. Any associated guarantees should clearly be outlined. For large, complex projects, sufficient time should be allowed so that the supplier can develop an accurate and comprehensive proposal. Upon receipt and evaluation, a proposal review meeting should be scheduled with both project teams. The proposal should be completely reviewed to ensure that the project scope has been met and no items or issues are left unaddressed. Items provided/not provided by supplier or customer should be reviewed. After complete review and technical acceptance of the proposal, the next step is the purchase of the system.

The path from purchase to delivery Once a large capital system is purchased, the clock automatically starts. Drawings are completed for approval and a submittal package is assembled. Long lead or difficult to obtain parts should be
purchased early. For certain projects and systems, a post-purchase site meeting is required, sometimes in conjunction with the submittal meeting. After the drawings have been released, fabrication and assembly begins. A quality vendor will have an open shop policy, allowing the

customer to inspect the system at any time during fabrication. As the delivery date nears, communication must remain effective. Staging areas for equipment should be prepared, any utilities or infrastructure requirements should be arranged and any existing equipment removed or prepared for removal. As an example, concrete work takes approximately one month to cure effectively. These efforts will help maintain the timeline for installation. Should a fast delivery install be required, the customer must have realistic expectations. Often a penalty for late delivery is written into the contract, although it is not unheard of for suppliers to take the penalty at a higher initial purchase price, still be late and pay the penalty from the additional funds. The acceleration of any schedule can increase costs. It is important that adequate time be budgeted. Finally, safety should be paramount at all times for the supplier and the customer.
Project startup Startup efforts are initiated as equipment installation nears completion. The vendor will run the system to refine its operation and performance and ensure that it meets the project specifications. It is critical to have a customer representative working alongside the supplier when requested. Most capital projects have a specific startup and training schedule that should be coordinated with the appropriate customer personnel to maximize the benefit.

SOFTWAREGUIDE 2012 Environmental Software Review By ROY BIGHAM he world economy is showing signs of gaining momentum. Some may disagree with that outlook but I think many will agree. Corporate and independent budgets are being scrutinized to ensure that the projects for the next year are going to have a good return on investment value. In many, if not most, cases, that also means increasing productivity while maintaining or lowering costs. A good way to accomplish that goal is to install and utilize appropriate software to lessen the burden of the staff. Programs today can interface with a variety of sensors to gather and disseminate data in a report form that is useful to management. The systems are capable of making routine decisions and process

changes as needed. If the parameters do go outside defined limits, the program can be set to notify the proper employee or to shut down the systems until help is available. So, Pollution Engineering has again gathered together a list of software that can accomplish the above and much more. One thing that stood out to us was that software companies that responded to our questionnaire dropped property transfer audit coverage. We think that was due to the All Appropriate Inquiry rule that came into effect. On the other hand, more companies are developing software that can be used with a Smartphone or tablet system. The contact information for the software suppliers that responded to our questions can be found below. A chart that can be used to quickly compare software capabilities is found on the following pages.

MATS Primer
IInn the the middle middle of of December, December the the EPA EPA announced announced their th latest new air regulation.
By ROY BIGHAM
O
n Dec. 16, 2011, the EPA signed the Mercury and Air Toxics Standards (MATS) regulations. They subsequently held a news conference to explain the new rules to the press. However, only those organizations that could arrive there in less than 24 hours could attend and there was no teleconference or video coverage available, at least to the best of my knowledge. The new rules are expected to have a huge impact on power companies and suppliers to those industries. The EPA said that there was a lack of emission standards for toxic air pollutants such as arsenic, mercury and other metals. MATS will correct that deficiency and require power plants that use coal or oil to meet the new standards. Coal is used to provide about 45 percent of power in the United States. Oil or petroleum is used to supply about one percent. See Figure 1 for a breakdown by energy source at this point in time.
Some history The last major Clean Air update was in 1990. In 2000, the agency proclaimed that there was sufficient scientific studies that determined it was appropriate, and even necessary, to control mercury emissions from power plants. Power plants were singled out because they contributed more of the metal to the air than any other industrial sources. Previous administrators attempted to put controls on the emissions but the rules were struck down by the courts. Furthermore, the courts required the

EPA to develop standards that followed existing law and properly used science, such that human health and the environment would be protected. Some states had become nervous about what appeared to be a lack of progress by the federal administration. Oregon passed the Utility Mercury Rule that required coal-fired power plants to reduce mercury emissions by 90 percent by July 1, 2012. Illinois Gov. Rod Blagojevich signed a state rule that required 90 percent mer-
cury reduction by Dec. 31, 2012. At least five other states also had such requirements in place that were stricter than the federal regulations. The EPA said that they had determined that three years should be sufficient for industry to comply with the new rules. However, they also concede that the cost and supply may require additional time for industry and the states to work together. So, the rules allow a state to provide up to one additional year to comply.

MATS Primer
Source is a presentation given by Gina McCarthy, EPA’s assistant administrator for the office of air and radiation, at the 2011 EUEC conference.
Why do we need these limits? There have been many studies that concluded mercury in the fish came from air pollution that settled in the water and was eventually consumed by the aqueous creatures. There had been questions about the validity of the test methods as mercury had been found in fish that had spent their entire existence in an aquarium but showed high mercury levels. The only explanation that made sense was that it came by air. The water in the aquariums had been filtered and treated to remove contamination, so that could not have been the source. The new regulations are expected to lower mercury emissions by 90 percent from power supply plants, 88 percent of the acid gas emissions, and SO2 by 41 percent. The EPA predicts that the application of the MATS, along with the Cross-State Air Pollution Rule, will save healthcare costs of up to $380 billion, prevent up to 46,000 premature deaths, 540,000 asthma attacks, 13,000 emergency room visits, and two million missed work or school days each year. The agency predicted that the cost to industry would be $9.6 billion. Before the decisions were finalized, the EPA received more than 900,000 comments from the public. 40

Health impacts Mercury is found in most coal formations. When the coal is burned, the mercury is released. From there the mercury changes form to make new compounds. Some of it settles on the land or in the water. Science has determined that when the mercury reaches the water, microorganisms change it to methylmercury, which is highly toxic. Fish and shellfish consume the microorganisms and the toxic compound is stored in the fat cells. Humans or other life forms consume the fish and the methylmercury. Always make sure to check with the state fish and wildlife agency to determine if there are any special advisories for eating the local fish. Certain people, such as women who plan to become pregnant or are already, as well as nursing mothers, and young children, should avoid species that are known to carry high levels of mercury. Examples of high mercury species would be shark, swordfish, tilefish or king mackerel. Rather,
one should eat shrimp, canned light tuna, salmon, Pollock or catfish in moderation. For children, babies and fetuses, the primary health impact of consuming methymercury is impaired neurological development. Exposure is often the result of the mother consuming contaminated fish during pregnancy. Studies by a variety of universities and health organizations have concluded that exposure to the chemical has impacted cognitive thinking, memory, attention, language, and fine motor and visual spatial skills. According to the Centers for Disease Control (CDC), mercury is generally found in three forms, elemental, inorganic or organic. Elemental mercury is the liquid form at normal temperatures that we think of in thermometers and electrical switches. Inorganic forms when elemental combines with substances such as oxygen or sulfur. Organic is normally formed in water when the mercury combines with a carbon compound. The more common compound is methylmercury but thimerosal or phenylmercuric acetate can also easily be formed. The CDC study found that most people have some level of mercury in their blood stream, but it is usually low enough to not be a concern. High exposure to mercury vapors can cause lung damage, while long exposure to lower vapor levels have been known to lead to neurological disturbances, memory problems, skin rash and kidney abnormalities. The study also showed that ingesting high levels of inorganic mercury can irritate and corrode the digestive system. Long exposure to lower amounts can have the same impact as long exposure to low vapor levels of elemental mercury. Inorganic mercury can be converted by microbes to organic forms. Long exposure to levels of organic mercury has caused damage to nervous systems. Infants born to women exposed to

More benefits There are about 1,400 coal- and oil-fired electric generating units operating at approximately 600 locations to provide power to the public. According to the EPA, these plants emit 50 percent of all the mercury emissions, 75 percent of all the acid gases, and 20 to 60 percent of all the
es to 1990 levels. In this writer’s opinion, this is not realistic. Go to YouTube and put in the search terms, “Obama prices will skyrocket” and listen to the predictions the President made many times in his campaign. I know this is not the cap and trade bill but this would only add to the burden and any attempt to declare that more regulation is going to lower electricity prices to less than they were over 20 years ago seems antithetical to common sense.

metals into the atmosphere. Many of these plants have not been upgraded in decades. In some cases, upgrades were delayed until the industry had better direction from the authorities on just what would be needed. Most of these units are more than 30 years old and many of them are over 50 years old (see Figure 2). So, upgrading them will not only reduce emissions but also improve output efficiency. The EPA estimates that the rules will require approximately 46,000 short-term jobs to construct the infrastructure. It will further require about 8,000 new positions in the long term to provide support to operate and maintain the equipment as well as the regular reports that will have to be generated to demonstrate the efficiency of the processes. Finally, the EPA said they expected that the addition of the required technology would have a minimum impact on electrical costs. They estimated that retail prices would increase by approximately three percent. However, they followed that statement with a comment that they expected demand for natural gas to increase, as some companies would choose to move away from coal and that would drive pric-
What is needed? Controlling mercury emissions at power plants is the last leg of the three highest sources to be regulated. The industrial sectors constituted about 67 percent of the mercury emissions in the United States. The three sectors were medical waste incinerators, municipal waste combustors and power plants. Medical and municipal waste burning operations have been regulated for some time and those sectors have accomplished the reduction of mercury emissions by more than 95 percent (See Table 1). Additionally, standards were set for some of the other sources such as cement production and steel manufacturing that reduced mercury emissions. Now it is the power providers’ turn to cap their emissions. According to the EPA, it is not necessary to develop new treatment technologies. The methods and equipment exist and are available to industry. See Table 2 for suggestions. The MATS sets standards for all Hazardous Air Pollutants (HAPs) emitted by coal- and oil-fired power generators with a capacity of 25 megawatts or greater. These are called national emission standards for hazardous air pollut-
ants (NESHAP), also known as maximum achievable control technology (MACT) standards. Coal- and/or oil-fired electric utilities emit many of the 187 HAPs listed in the Clean Air Act. Standards set under the toxics program are federal air pollution limits that individual facilities must meet by a set date. MACT for new sources must be at least as stringent as the emission reduction achieved by the best performing similar source. Existing source MACT standards must be established to be at least as stringent as the emission reductions that have been achieved by the average of the top 12 percent best controlled sources. Setting a MACT standard is a two step process: 1. The MACT floor is established based on what is currently achieved by sources – costs may not be considered. 2. The EPA may regulate beyond the floor where it can be justified – costs and other issues must be considered in this event. Some large energy suppliers have made the claim that these regulations will require them to decommission some of their plants. The news sources I read, which reported these statements, left it at that. The inference from reading the stories was that rules would lead to shortages. Shortages would lead to higher prices and brownouts. That is just not going to happen. The consumption of electricity is increasing. Many are predicting that the future of the automobile industry is in plug-in cars and those will need more power. Most appliances continue to pull electricity even when they are turned off. Nearly every cell phone charger continues to draw electricity when it is not connected to a phone. This means that there will continue to be a market for electricity for the foreseeable future. Homes will not become self sufficient any time soon. If a company does decide to close a generating facility, it probably needed to be replaced anyway. Most likely that company will simply build a new facility that will run much more efficiently and, if not, another will be there to grab up that market.

CASEBOOKCANADA By Dianne Saxe, Ph.D.
A Bumper Crop of Convictions Although municipal drinking water is considered safe for consumption, does it actually have a negative impact on contaminated site cleanups? n average, the Ontario Ministry of the Environment launches nearly 150 to 175 prosecutions for environmental infractions each year. Approximately 75 percent of such prosecutions are resolved once the accused pleads guilty, while roughly five percent are acquitted at trial. At the same time, nearly 10 percent are convicted and about 10 percent are withdrawn. Thus, 12 or so convictions are expected to be adjudicated in a typical month, generally for rather minor offences, resulting in modest fines.
O
“
… the average municipal drinking water, while safe to drink, could potentially derail the success of a site cleanup program.
”
The month of November 2011, however, was witness to a bumper crop of environmental convictions. During the last few weeks of that month alone, the ministry announced more than two dozen convictions, for everything from failing to file an annual report for its waste disposal site (Smooth Rock Falls, $5,000) to an $85,000 fine for illegally dumping auto fluff in an unlicensed quarry (Kimco Steel and Charles Dietrich Construction). Four convictions involved the prosecution of municipalities. The Ministry continues to actively enforce its full range of statutes, including the Environmental Protection Act, the Ontario Water Resources Act, the Pesticides Act and the Safe Drinking Water Act. Federal enforcement remains comparatively weak, with only three convictions in the same time period for the entire country: two for wildlife violations (with a maximum fine of $14,500) and one under the Fisheries Act.
Wonderful water Meanwhile, Eric Hood, a Senior Environmental Consultant for Golder Associates Ltd., has noted that municipal drinking water often fails to meet Ontario’s contaminated site cleanup standards, with potentially serious consequences for cleanups. With so many challenges facing a successful site
42

clean-up program, it would be easy to overlook something as simple as the drinking water that comes from the tap. But municipal drinking water presents such challenges because the chemical composition of this ubiquitous resource may actually be adding contamination, based on the Ministry of Environment’s new site condition standards for groundwater. Municipal drinking water contains trace concentrations of specific VOCs known as trihalomethanes, which are formed as a result of chlorination in water treatment plants. Chloroform is the most common trihalomethane, and according to Health Canada, the average chloroform concentration in Canadian drinking water is 47 μg/L. The new site condition standards for chloroform, which came into effect on July 1, 2011, varies between two and 22 μg/L. Therefore, a discharge of drinking water to the subsurface could exceed the site condition standard, implying that the property where the discharge occurred could be considered “contaminated.” This is particularly relevant for Table 3 (non-potable) sites, where the chloroform standard for groundwater has become much more stringent. A common source of chloroform in groundwater is leakage from municipal water distribution systems and sanitary sewers; however, in some instances, municipal water is used for environmental drilling and discharged into groundwater. In this circumstance, straightforward technical measures can be applied to prevent any potential for chloroform contamination, such as aggressive well development to remove any injected water. It remains to be seen whether this type of groundwater contamination ever becomes an obstacle to obtaining a Record of Site Condition. That said, it does raise the awkward possibility that the average municipal drinking water, while safe to drink, could potentially derail the success of a site cleanup program. PE

PRACTICALMANAGEMENT By Norman Wei
Caveat Emptor - Buyer Beware Not engaging a properly qualified professional to accomplish due diligence will nearly always be a costly mistake. ollowing the 1980 Love Canal debacle, Congress enacted the Comprehensive Environmental Response Compensation and Liability Act, commonly known as the Superfund Law. Under this law, any owner or operator of a contaminated site is held strictly liable cleanup. Landowners, who unknowingly purchased contaminated property, were at risk for all cleanup costs. In 1992, Congress amended the Superfund Law to include an “Innocent Land Owner” defense (ILO) against Superfund liability. If a purchaser conducts environmental due diligence before completing the sale, he will receive some protection from Superfund liability if the commercial property he purchased turns out to be contaminated. The due diligence process is codified in the federal regulations as All Appropriate Inquiries (AAI), which is commonly called a Phase 1 Environmental Assessment. To qualify for an ILO, the AAI must be performed or supervised by an Environmental Professional (EP). The qualifications of an EP are codified in the federal regulations. The AAI requires the following: • Interviews with past and present owners, operators and occupants; • Historical documentation reviews; • Reviews of federal, state, tribal and local government records; • Visual inspections of the facility and adjoining properties; • Obtain commonly known or reasonably ascertainable information; • Environmental lien searches; • Assessments of any specialized knowledge or experience of the prospective landowner; and • An assessment of the relationship of the purchase price to the fair market value of the property, if the property was not contaminated. A professionally prepared Phase 1 report will generally cost several thousand dollars or more, depending on the size and history of the commercial property. Unfortunately, low-ball Phase 1 mills are popping up everywhere. These are firms, or sole proprietors, that charge $800 or less to “perform” a Phase 1 assessment for a commercial site. Many buyers, lenders and sellers are hiring these mills because of the low costs. The cheaper product may well cost more in the long run. For instance, the seller can be sued, the lender can be
F
held liable, or the buyer might not be allowed to claim the ILO exemption. On the other hand, paying a lot of money does not guarantee success either. The EP must be properly qualified and the field technicians properly supervised. A recent Michigan case illustrates the risks associated with the failure to conduct proper due diligence. In Alfieri v. Bertorelli, 2011 Mich. App. LEXIS 1796 (Mich. Ct. App. 10/18/11), the buyers purchased a condominium unit in a former factory building as an investment. The factory had been impacted with trichloroethylene (TCE) from its former use. A newspaper article, as well
“
Landowners, who unknowingly purchased contaminated property, were at risk for all cleanup costs.
as the real estate agent’s sales brochure, indicated the site had been remediated despite the fact that the state agency had advised the realtors that the sales brochure was inaccurate and misleading. The buyers relied on the newspaper article and the sales brochure and did not perform their own due diligence before closing the deal. The property turned out to be heavily contaminated. The buyers subsequently filed a lawsuit against the real estate agents on theories of silent fraud and negligent misrepresentation. The jury found that the agents engaged in negligent misrepresentation. However, the jury also determined that the buyers were partially responsible for their damages because they had failed to perform their own due diligence. The jury assigned the buyers 35 percent fault on the negligent misrepresentation claim. Moral of the story? Buyers beware and hire qualified EP to do due diligence. PE

In-Situ Flushing and PRBs This month we look at two more groundwater contamination treatment methods that were commonly used in the past – in situ flushing and permeable reactive barriers. n the past, in-situ flushing was used to clean up harmful chemicals in polluted soil and groundwater by pumping water or chemicals into the ground. The harmful chemicals are flushed toward wells where the materials are pumped out. The process works in situ, which means the polluted soil is cleaned up in place rather than excavating.

(PRB) may require many years. The time period depends on two major factors that vary from site to site: • The type and amount of pollution present in the groundwater • The time required for the groundwater to move through the PRB Groundwater may move a few inches to hundreds of feet per year, depending on site conditions.
Is in-situ flushing safe? In-situ flushing can be quite safe, but there are also some potential hazards. First, workers must wear protective clothing if they handle chemicals and provide protection against exposure to surfactants or co-solvents left behind after cleanup. At some sites, scientists may want to leave small amounts of surfactant or co-solvent in the polluted area to help with bio-remediation.
How long will it take? The duration of the i- situ flushing process typically depends on several factors: • The size and depth of the polluted area • The type and amount of NAPL • The type of soil and conditions present • How groundwater flows through the soil (how fast and along what path?) To properly clean a site, in situ flushing may require months or even years.
Why use in-situ flushing? In situ flushing is also one of the few methods that can help clean NAPL in place. This avoids the expense of digging up the soil for disposal or cleanup. Depending on the number of wells and the amount of surfactant or co-solvent needed, in-situ flushing can be expensive and difficult to use. However, in-situ flushing has successfully cleaned up many polluted sites and has been used, or is being used, at 16 Superfund sites across the country.
Permeable reactive barriers This method uses a trench backfilled with reactive material such as zero valent iron filings, activated carbon or peat, which absorb and transform the contaminant as groundwater flows through the barrier.

Are PRBs safe? PRBs have a proven safety record. Once built, there are no moving parts, equipment or noise. The reactive materials placed in the PRB trench are not harmful to the groundwater or to people. The reaction occurs below ground so that cleanup workers can avoid contact. Some soil, which may be polluted, must be removed when digging the trench. Follow all safety rules. EPA requries air test to ensure that dust and gases are not released.
Why use PRBs? PRBs tend to work best at sites that have loose, sandy soil and a steady flow of groundwater. Since PRBs clean up many types of pollution underground, as long as it is no deeper than 50 feet, there is no need to pump polluted groundwater above ground; therefore, PRBs can be cheaper and faster than other methods. Additionally, very little waste needs to be disposed of in a landfill, which also saves money. There are no parts to break, and there is no equipment above ground so the property can be used while it is being cleaned up. There are also no energy costs to operate a PRB because it works with the natural flow of groundwater. And, since they are so costeffective, PRBs have been installed at more than 40 sites in the United States and Canada thus far. PE
