Water and electricity do not mix. While it was important to ensure the stormwater was removed from the substation, it was also necessary to make certain no oil would escape the site and it all had to be automatic.

Three prominent professionals shared their knowledge of innovative methods of treating contamination in soil and groundwater in place. Read the newest white paper provided by Abanaki. Using existing monitoring wells, oil skimmers alone can often treat water to required levels for far less cost than traditional pump-and-treat methods. A new generation of oil skimmers, some solar powered and fitted with new high-nap skimming media, can even remove light fuel oils. By avoiding pump systems, environmental engineers dramatically reduce project cost and reduce maintenance needs.

EDITOR'SDESK Remediation Review The Georgia Institute of Technology joined with Pollution Engineering for three days of innovative remediation technologies.

I

n the middle of May, Pollution Engineering and the Georgia Institute of Technology joined to bring a collection of presentations to a conference held in Wheeling, Ill., just north of Chicago. The event was called the RemTEC Summit 2011. And I know it’s our own event and all, but the only way to describe the talks is just to say “wow!” Jerry Schnoor, professor at the University of Iowa and executive editor for the journal, Environmental Science and Technology, launched the conference with some of the innovative work he and his students were involved with involving phytoremediation. The quality of the talks continued over the next two and a half days as presentations from academia and industry leaders provided the latest gains in remediation technology. The goal was to provide an atmosphere that was conducive to sharing knowledge. From the comments I heard from some of the exhibitors and people in the aisles, I think we did just that. We were also asked if we could do this again as there is still a lot to learn. We also wanted to know how we could improve the experience next time. I should let everyone know that we are planning to do this again. As soon as we can nail down a date, I will post it. One question I got often was, what was the role of our title sponsor, Arcadis. I really want to give that company a hearty thank you. They lent us the experience of many of their scientists to help us review the mountain of submissions from people wanting to give talks and present posters. They also purchased a Title Sponsorship so their name was prominent but the event was organized by us and Georgia Tech. Arcadis’

involvement was very valuable to us and the event would not have had the quality it did without them. I noticed as I looked at the attendance list that over 90 percent seemed to be from environmental consulting companies. I am not sure why there were not more people from industry there. I know that I used to like to attend similar conferences just to keep up with the latest technologies. I can still recall attending my first presentation some 30 years ago when a professor talked about using plants to remediate contamination from soils. The idea seemed farfetched and the questions flew after the talk. Today, even though there is still a lot to learn, the process is well accepted and utilized around the globe. Anyone who is charged with environmental control for a company should stay up to date on remediation technology so they can properly choose the right technologies and companies for a problem they may encounter during their career. Although we take all the precautions we can and write plans, the unexpected will almost inevitably happen and the environmental engineer will have to make informed, supervisory decisions to ensure things are done properly. The aggravation that can be saved is worth a fortune. PE

Remediation Business on the Up According to the results of an industry survey, there are signs that the remediation market has started to grow. According to the Environmental Business Journal, 2010 witnessed a growth in the United States remediation business segment of 2.9 percent to reach $7.7 billion in total annual revenue. This was the conclusion of a research survey conducted by the company that was published in their EBI Report 319. The federal Department of Defense and Department of Energy were again the strongest customers for remediation projects. Excavation with off-site disposal, and cap and contain methods remain the top technologies used in the majority of projects. Nearly two-thirds of the total revenue was generated by remediation construction with the rest used for consulting, design and analytical work. Commercial and residential work came in at the bottom of the list of consulting work. Fewer than 18 percent of the respondents reported a decline in revenue in 2010. That compares to 31 percent in 2009. It is believed by companies in the industry that revenue in 2011 will mostly be driven by state enforcement activities. A copy of the 605-page report can be ordered through http://ebionline.org/environmental-industry-researchreports/8-report-319.

AIR Natural Gas Can Cut Emissions The Massachusetts Institute of Technology released on June 9, 2011, the results of a study that determined increasing the use of natural gas to generate electricity could cut CO2 emissions. It is estimated that by making the switch, CO2 emissions could be cut by nearly 8 percent, which is half of the unofficial reduction goal planned by 2020. The report replaced coal-fired power plants with natural gas fired facilities. The report stated that renewable sources such as solar and wind would not be capable of providing all of the electrical needs. Natural gas facilities can be brought online much quicker than coal plants as well and make an excellent way to back up renewable energy sources. A copy of the report, The Future of Natural Gas, can be downloaded from MIT’s website at http://web.mit.edu/mitei/research/studies/natural-gas-2011.shtml.

EPA Finalizes GHG Confidentiality Determinations The EPA finalized the confidentiality determinations for certain data elements that are required to be reported under the Mandatory Greenhouse Gas Reporting Rule. The action also finalized amendments to the special rules governing certain information obtained under the Clean Air Act, which authorizes the EPA to release or withhold as confidential reported data under the Mandatory Greenhouse Gas Reporting Rule according to the final determinations for such data without taking further procedural steps. The EPA did not include final confidentiality determinations for data elements that are in the Inputs to Emission Equations’ category.

PEOPLE The Board of Directors of Vanton Pump & Equipment Corp., has appointed Lawrence Lewis as president and Kenneth Comerford as vice president. The original quarry around 1900 that sparked the company’s first invention.

Celebrating 100 Years Viking Pump, a unit of IDEX Corp. turned 100 this year. The company can trace its origins back to Jens Nielsen, an emigrant from Denmark to Cedar Falls, Iowa, in 1870. Nielsen operated a limestone quarry that suffered from water infiltration. To solve the problem, he developed the first rotary internal gear pump to remove the water. A patent application was filed in 1905. In 1911, he joined with P.C. Petersen (machinist), W.L. Hearst (doctor) and George Wyth (shoe salesman) to form the Viking Pump Co. They chose the name as they three of the four of them shared a Danish decent. The company has several events planned to celebrate their centennial birthday. They are planting 100 trees, organizing a 5-K run/walk to benefit United Way and creating a company museum. The company’s world headquarters are still located in Cedar Falls.

WASTE EPA Cuts Chemical Confidentiality Claims The EPA has made public the identities of more than 150 chemicals contained in 104 health and safety studies that had previously been claimed confidential by industry. The June 8, 2011, announcement is another in a series of actions that the EPA is taking in the name of providing the public with greater access to information on the chemicals that are manufactured and used in the United States. For these 104 studies, the chemical identity will no longer be redacted, or kept from view. The chemicals involved are used in dispersant formulations and consumer products such as air fresheners, non-stick and stain-resistant materials, fire resistant materials, nonylphenol compounds, perfluorinated compounds, and lead. “This action to disclose the identity of more than 150 chemicals is an important step in EPA’s commitment to give the American people access to critical information about chemicals that their children and families may be exposed to,” said Steve Owens, assistant administrator for EPA’s Office of Chemical Safety and Pollution Prevention. “A health and safety study with the chemical name kept secret is completely useless to the public.” In 2010, the EPA challenged industry to voluntarily declassify unwarranted claims of confidential business information (CBI). The agency also issued new guidance outlining plans to deny confidentiality claims for chemical identity in health and safety studies under the Toxic Substances Control Act (TSCA). Based on this guidance, the EPA notified a number of companies in February 2011 that the agency had determined that their CBI claim was not eligible for confidential treatment under TSCA and that the EPA intended to make the information public.

New Chemicals Covered in TSCA Listed Section 5 of the Toxic Substances Control Act (TSCA) requires any per-

ENVIRONEWS son who intends to manufacture (defined by statute to include imports) a new chemical (i.e., a chemical not on the TSCA Inventory list) to notify the EPA and comply with the statutory provisions pertaining to the manufacture of new chemicals. The document covers the period from Dec. 3, 2010 to Jan. 31, 2011, and provides the required notice and status report. It consists of premanufacture notices (PMNs) that are pending or expired, and the NOC to manufacture a new chemical that the agency has received under TSCA section 5 during this time period. The EPA classifies a chemical substance as either an “existing” chemical or a “new”chemical as defined by the regulation. Any chemical substance that is not on EPA’s TSCA Inventory is classified as a new chemical, while those that are on the TSCA Inventory are classified as an existing chemical. The EPA is required to publish in the Federal Register a notice of receipt of a pre-manufacture notice (PMN) or an application for a test marketing exemption (TME), and to publish periodic status reports on the new chemicals under review and the receipt of notices of commencement (NOC) to manufacture those chemicals.

The EPA is making it easier to find data about chemicals. Two new databases – the Toxicity Forecaster database (ToxCastDB) and a database of chemical exposure studies (ExpoCastDB) – were released that scientists and the public can use to access chemical toxicity and exposure data. ToxCastDB users can search and download data from over 500 rapid chemical tests conducted on more than 300 environmental chemicals. It includes a tool that can predict the potential tox-

icity of chemicals and provide a more cost-effective approach to prioritizing which chemicals of the thousands in use require further testing. ToxCast is currently screening 700 additional chemicals, and the data should be available in 2012.

11

ENVIRONEWS can obtain summary statistics of exposure data and download datasets. The EPA will continue to add internal and external chemical exposure data and advanced user interface features. The new databases link together two important pieces of chemical research – exposure and toxicity data – both

of which are required when considering potential risks posed by chemicals. The databases are connected through the agency’s Aggregated Computational Toxicology Resource (ACToR), an online data warehouse that collects data on over 500,000 chemicals from over 500 public sources.

Users can now access 30 years worth of animal chemical toxicity studies that were previously only found in paper documents, data from rapid chemical testing, and various chemical exposure measurements through one online resource.

San José, Calif., Mayor Chuck Reed and EPA Regional 9 Administrator Jared Blumenfeld launched the Clean Creeks, Healthy Communities pilot program at a press conference to highlight a significant pollution problem impacting the San Francisco Bay. The pilot program will be aimed at reducing pollution and improving water quality along a 3-mile stretch of Coyote Creek. The program will employ and assist the homeless, deter dumping and litter, and engage neighbors as creek stewards along the waterway. “This pilot program uses an innovative and collaborative approach to restore the health of Coyote Creek,” said Reed. “I’d like to thank the EPA and our other local partners for providing the bulk of the funding necessary to help foster the longterm stewardship of our local waterways.” “Trash pollutes the environment, and it spoils our enjoyment of San Francisco Bay,” said Blumenfeld. “EPA is pleased to augment state and local efforts to improve water quality, providing support for a project that will eliminate a major source of trash reaching the Bay.” Trash, toxic household products and human waste along the creek between Tully Road and East William Street have severely compromised water quality. In the last three years, the water district and the city have pulled approximately 300 tons of trash from homeless encampments and trash accumulations. Of this, approximately 150 tons were from the project area. More information is available at http://www.epa.gov/region9/ mediacenter/cleancreeks/ or use the smartphone mobile tag.

LEGALLOOKOUT By Lynn L. Bergeson

Inter-Atlantic EPA Trade efforts between the U.S. and E.U. should be improved by coordinating regulatory efforts. n an important and under-appreciated May 3, 2011, Federal Register notice, the U.S. Department of Commerce International Trade Administration (ITA) requested public comments concerning regulatory cooperation between the U.S. and the E.U. that would help eliminate or reduce unnecessary divergences in regulation and in standards used in regulation that impede U.S. exports. Of critical importance, ITA acknowledged that the main impediments to greater trade and investment between the nations “are not tariffs or quotas, but rather differences in regulatory measures.” This could be an important opportunity.

I

Background President Obama linked trade to job creation when he announced the National Export Initiative in his 2010 State of the Union address and “set the ambitious goal of doubling U.S. exports in the next five years to support millions of jobs here at home.” Since 2005, the U.S. has worked with the European Commission, within the framework of the High Level Regulatory Cooperation Forum (HLRCF), to strengthen regulatory cooperation, promote better regulation, and reduce or eliminate unnecessary regulatory differences. In December 2010, the Transatlantic Economic Council, comprised of cabinet-level officials from both organizations, endorsed several initiatives intended to promote regulatory cooperation, including directing the HLRCF to develop a process for identifying secto in which the countries “could pursue upstream regulatory cooperation.” According to the ITA, trade between the U.S. and E.U. may be impeded because countries apply different standards or technical requirements to address common environmental, health, safety or other concerns with respect to certain products or product categories. In some instances, the divergences may be arbitrary and could lead to delays, additional costs, and burdens on U.S. suppliers, making it difficult for them to penetrate foreign markets. The ITA states that in other cases, however, the divergences “may be necessary to achieve legitimate objectives such as the protection of the environment and public health and safety.” Cooperation with respect to regulation and standards used in regulation can help reduce unjustified divergences, and lower costs and burdens for businesses, as well as for governments and consumers. ITA used an example of regulators in different countries legally sharing full data, studies and other information on

specific regulatory issues, stating that, in such cases, the regulators “are more likely to reach similar conclusions, such as on the risks associated with a particular product, appropriate measures to mitigate those risks, and the costs and benefits associated with alternative regulatory approaches.” According to ITA, this can lead regulators to adopt regulatory measures that are more aligned with each other, allow producers to develop economies of scale, reduce compliance costs associated with divergent regulatory measures, and pass on cost savings to consumers.

“

This could be an important opportunity.

ITA specifically requests public comment on the following possible types of cooperative regulatory activities: • Information-sharing agreements; technical assistance; memoranda of understanding, mutual recognition agreements; • Collaboration between regulators before initiating rulemaking proceedings; agreements to align particular regulatory measures; • Equivalency arrangements; and • Accreditation of testing laboratories or other conformity assessment bodies. Submitters should be as specific as possible in describing the relevant product or product sector in which they believe there is an opportunity to facilitate trade without undermining U.S. public health, safety, environmental and other legitimate policy objectives. ITA states that it is interested in receiving recommendations concerning any product sector that, due to the volume of trade between the U.S. and EU, “is a justifiable focus of enhanced regulatory cooperation.” Collaborative responses are encouraged.

Save Energy and Lower Carbon Emissions Often the simple overlooked fixes can provide the greatest returns in a relatively short time period. ompanies launch energy-efficiency measures for many reasons, including proactive compliance with the ISO 50001 energy management standard expected later this year. The Pew Center on Global Climate Change’s From Shop Floor to Top Floor: Best Business Practices in Energy Efficiency highlights best practices driven by commitments to reduce their carbon footprints. High energy costs are forcing changes. Start with a comprehensive assessment that identifies potential energy savings. The experience of Sherwin-Williams’ Richmond, Ky., facility demonstrates the value such an assessment can deliver. The plant employs a lean manufacturing business model that promotes process streamlining, quality improvement and waste reduction. In 2008, the plant contacted the Department of Energy’s Industrial Technologies Program (ITP), which provides technical assistance to companies in identifying projects with the potential to improve efficiency. Among the projects were six related to the plant’s boiler steam system. All six projects were implemented. Steam trap surveys were undertaken to identify any leaks in the pipe system and upgraded valves were installed. Heat exchangers were added on all condensate return systems to capture waste heat. Additional heat was captured by using removable steam blankets. The plant’s boiler offered a great opportunity for energy efficiency. Waste heat from the boiler and other utilities was used from November through March to reduce the factory’s heating requirements. It also became clear that the plant’s main boiler had excess capacity for much of the year. To eliminate that waste, the plant switched from its main 700hp boiler to a 300-hp backup boiler for its primary steam production. The plant expects to keep the smaller boiler in use for about 10 months a year for process and facility heat, and bring the larger boiler online when needed. The plant’s insulation, lighting and compressed air system were upgraded. According to ITP’s review of the project, the plant reduced its energy intensity by 26 percent.

One of the more important recommendations flowed from the observation that its natural gas consumption had noticeably dropped. The assessment team recommended an analysis of the boiler stack gases used to heat the chrome tanks and evaporate wastewater. When the analysis revealed that the boilers were burning rich, technicians quickly adjusted settings to achieve recommended burn ratios. Based on the greaterthan-expected savings from the boiler adjustments, company executives implemented a program to ensure proper functioning of the plant’s gas lines. The inspection identified a number of small joint leaks, which were promptly repaired. After implementing the boiler and gas line improvements, the plant’s natural gas use dropped by 12 percent, even as production increased. A comprehensive assessment of a site’s energy needs and potential improvements is always an important step. Facilities that participate in the ITP program save an average of $55,000 a year with a payback period of 12 months. That makes sense, no matter why a company launches the process. PE

Sustainability Jeopardy Finding a clear definition for ‘sustainable’ means being able to answer in the form of a question – or maybe many questions ithout a doubt, we have heard the phrase, “If you have any questions, just ask.” Most of the time, that is easier said than done. As an example, I asked my friend and retired Ohio EPA manager Gerald Rich, “What is sustainability?” Without hesitating he fired back at me with a Socratic machine gun, answering my question with a barrage of what were either questions or a script stolen from Alex Trebek. It was also very enlightening, and so I pass it on to you. It is the definition of sustainability:

• What are the U.S. federal laws, regulations and guidelines pertaining to sustainability? • What are the voluntary programs? • What is the GHG emissions inventory? • What is the carbon neutral program? • What is corporate social responsibility and how does that impact sustainability? • What works and, perhaps more importantly, what doesn’t work? • What are the economics of sustainability? • What are the different solar, geothermal and wind power efforts being used at facilities? • What is carbon accounting? • What are the different strategies for CO2 reductions? • What are the different uses and applications for solar energy? • How can a facility’s sustainable efforts affect electrical power production? • How can you create a sustainability program for your employer? • What are the basic concepts of sustainability? • How is sustainability affecting businesses now? • How will sustainability affect businesses in the future? • What are the current assessment tools? • What organizations are associated with sustainable development?

• What are the government initiatives for sustainability? • What are the renewable energy systems for buildings? • What is sustainable lifecycle assessment? • How do you establish a carbon footprint for your company? • What is green electricity and how can it be used to bring down energy costs? • How do you sell sustainability efforts within your company? • What are the various sustainable building construction methods for a facility? • What is “mitigation banking of credits” for sustainability? • How can sustainability be measured? • Are there metrics for sustainability that can be used across industries? Another adage says “ask a dumb question, and you will get a dumb answer.” While my inquiry was not dumb, it was obviously not as complete and open-ended as I had originally intended it to be. Gerry’s answer was certainly not dumb as he probed to find out exactly what I wanted by my obviously incomplete question. Every day we run into situations where an accident may have occurred or a job does not get completed. Digging into the reasons for the problem, it can usually be found that someone did not ask the right question in the beginning to get the right answer. In the hectic world in which we live, it is important to take the time to carefully construct our questions, so that others can provide the exact kind and amount of information needed to properly formulate a helpful answer.

A group of leaders in the remediation industry talked about properly applying technology to meet cleanup goals. This is part one of a review of the discussion hosted by Pollution Engineering. erhaps no environmental field has witnessed as much radical advancement in the past few decades as in-situ remediation. New treatment techniques are revolutionizing how we approach cleanup of soil and groundwater. Remaining technically masterful of the latest advances – attending all of the conferences, reading all the White Papers – can be time consuming. For this reason, and for those who could not make it to the industry’s premier conferences like RemTEC or Battelle, Pollution Engineering gathered together some of the top scientists behind some new technologies to answer questions about their applications in one 90-minute program. On June 8, 2011, PE hosted a webinar that included three leading experts that are intimately involved in applying science to overcome problems found in our environment. Nearly 200 people attended the free live event online, and hundreds more have signed up to view it later (you can too – use the smartphone mobile tag link to register). Leading scientists in in-situ chemical, thermal and biological technologies, respectively, Dan Bryant of GeoCleanse, Ralph Baker of TerraTherm, and Sam Fogel of Bioremediation Consulting, shared information about each of these technologies in a slide presentation.

there was a question and answer period that lasted nearly 30 minutes. The questions that could not be addressed during the event were saved and sent to the speakers to provide answers back to the participants. The goal of the project was to increase knowledge and application of the science behind each technology. These are not the only technologies, in fact according to a recent report by the Environmental Business Journal ex-situ disposal remains the primary method of remediating contaminated soils. However these technologies are representative of the astounding new in-situ options available today that, if used appropriately, can save site owners millions of dollars and years of non-productivity. Jim Cummings from the EPA’s Technology Innovation and Field Services Division moderated the presentations in a most professional manner. His extensive knowledge of a variety of technologies that are applied to remediation in the United States and around the world was 24

apparent in his comments. He was able present questions from the audience so they were easy to understand and well defined. Cummings started the conference assuring the audience that the EPA does not endorse any specific application for any particular project. This month we will cover the material presented in the webinar itself. Then stay tuned for Part II in our August issue, as we follow up with each of the presenters in a question-and-answer session to supplement the Webinar.

Presented by Jim Cummings There is an increasing trend today toward the use of insitu remedies. In fact, many sites have managed to use a combination of remedies to achieve site closure (or deletion from the National Priorities List for EPA sites) more quickly. Another important trend aside from the kinds of technologies being used is the approaches or techniques that are being used. The industry has seen a marked increase in flexible, adaptive, iterative combinations to address all compartments that are prevalent at these contaminated sites. A couple of the quotations heard around the industry, at trade conferences, etc., highlight the need for such an approach. They note that sources tend to reveal themselves as the remedy progresses, particularly after contamination in the lower zones is addressed. Jim said, “Remedy implementation is just the next phase of site characterization.” Many insitu remedies will involve injection, meaning more holes, thus a greater opportunity to characterize the plume. The last trend involves the use of higher resolution tools in the site characterization phase today. As much as treatment options have grown, perhaps the technology for source identification and plume delineation has come even

further to provide greater accuracy in source and plume delineation. The desired end state for a remediation project means an adequate deployment of robust source term removal technologies, a timely transition to cost-effective polishing steps, reducing the need to pump and treat, and an appropriate reliance on monitored natural attenuation.

ISCO approaches and applications Presented by Dan Bryant Dan’s presentation focused on the chemistry and applications of three of the four primary chemical oxidants available for in-situ chemical oxidation (ISCO) remediation: • Catalyzed hydrogen peroxide (including variations like Fenton’s reagent and percarbonate) • Catalyzed persulfate, and • Catalyzed permanganate. Catalyzed peroxide, the oldest in the suite of oxidants, has been known since 1898 in wastewater applications, and continues to be used as such today. The chemical reaction is fairly simple, a reaction of hydrogen peroxide with ferrous iron to generate a hydroxyl radical: H2O2 + FE2

OH• + OH- + FE+3

It is the second-most powerful oxidizer

available to the industry and can destroy virtually all of the environmental contaminants that we are concerned with today. There are many other reactions associated with Fenton’s reagent that generate a wide variety of other oxidants and compounds to destroy contaminants. In most cases the reaction of the

PART I

a powerful oxidizer, and again there is a wide suite of chemical reactions that are involved that are capable of producing oxidants and reductants, depending on how the chemistry is adapted. When these radicals react with organic compounds the surprise for most people is that the reaction does not produce the same intermediate byproducts we would see with a biological application. Most ISCO intermediate compounds are cleavage products with apparent compounds (see Figure 1) that are hard to detect in the field, being so unstable. “Sometimes I can detect phenol in the laboratory, but that’s it,” said Bryant. For example, PCE will produce dichloroacetic acid and formic acid, attacking that double-carbon bond in PCE and cleaving that to form the intermediate compounds. All that can be detected in the field is the resulting CO2. The last option, permanganate, is not a radical-based system. With permanganate oxidation there are a couple of options: sodium permanganate, and potassium permanganate, basically different salts of the same anion. The anion is really the oxidant in these systems,

“

The industry has seen a marked increase in flexible, adaptive, iterative combinations to address all compartments that are prevalent at these contaminated sites.

hydroxyl radical with organic contaminants will completely mineralize the contamination down to CO2 and water, plus some other basic building blocks of the compounds (chloride, nitrate, etc.) Very similar to this is catalyzed persulfate, the “new kid on the block.” It has been in the market for just the last several years. Like catalyzed hydrogen peroxide, it is a catalyst that produces radicals. For example it will react with ferrous iron to produce sulfate radicals, which in turn can react with other compounds to produce hydroxyl radicals that interact with the contaminant (producing CO2, water and sulfates). It too can be

”

and works by epoxidation or addition. An example of this type of oxidation with ethenes can be seen in Figure 2. The permanganate will attach itself to the contaminant compound, forming a very unstable compound which can then break itself apart through either hydrolysis or carbon bonding cleavage. So how do we determine which oxidant to use? They all have pro’s and con’s. Table 1 shows Bryant’s personal opinion but he admits other scientists could have very different opinions on this, and plenty of individual site characterizations could change the formula for oxidant selection rather drastically.

PERMANGANATE OXIDATION OF ETHENES

For example, with a concentrated source of DNAPL peroxide (the least expensive formula) would also be the most effective, but in a dissolved plume you cannot get the same strength of a reaction with peroxide, but can with persulfate or permanganate. Permanganate’s forte is ethenes (PCE, TCE, DCE) and not much else; because it is not a catalyzed system it is the easiest to apply. In applications involving silt and clay, persulfate and permanganate can diffuse into that the materials, thus lasting longer and not providing the same challenges of peroxide. If used in combination with other treatments or follow-up treatments, the residuals left in the soil – different for each ISCO option – can matter a great deal. For example the sulfate left by persulfate is quite beneficial in a petroleum site if ISCO is to be followed by a bioremediation treatment, but would not help at all with a chlorinated solvent site. See Table 2 for a rundown of the various oxidizers’ respective effectiveness against various contaminants. Bryant noted that contaminant mass distribution – and an accurate conceptual site model – is very important for an ISCO application. In general, moderate to high permeability and moderate 26

to high concentrations will better lend themselves to an ISCO solution. Other considerations including the geology and hydrogeology of the site (e.g. limestone can create problems), and the groundwater chemistry. The cleanup objectives will determine how the application is approached. Typically ISCO is used for source reduction at one to two orders of magnitude, and for rapid NAPL treatment. It is an intense, daily process of constant data collection and audibles. As a combined technology, ISCO works well followed by bioremediation or MNA, or within itself by combining oxidants, or coupling with enhanced recovery (e.g. recovering coal tar). As the technology has evolved it has been expanding into new areas. Examples include the use of manganese to generate oxidants and reductants. Future applications of the technology have shown to be possible in a lab setting for emerging contaminants like PFOA/PFOS, and new oxidant technologies based on ferrate oxidant systems. Coming up in Part II this August: Some great questions were raised during the Q&A session after the webinar, but unfortunately we didn’t have time in the space allotted to answer them all at the time. In August, we will remedy this, as PE catches back up with all three presenters to follow up with both the questions posed during the webinar, and those we didn’t get to. PE

Such substations are constructed with drainage systems that collect rainwater to be channeled away from the electrical transformer and discharged into a nearby creek or tributary to a river. Because these initial distribution transformers deal with massive amounts of voltage, they are encased in several thousand gallons of oil for cooling.

Preventing oil spills Electrical distribution When power leaves any generating plant, it travels to massive substations that begin the distribution process. Electricity arrives at 500,000 volts and must be stepped down to a lower voltage for

In order to devise the most efficient containment system possible to protect against a transformer leak, the utility provided research funds to several engineering firms to design an interceptor and underground oil containment sys-

SAFEGUARDING tem for the two existing 500-kV substations. These computer-controlled substations are unmanned, and therefore the challenge of designing the system lay in its automation capability to sense an oil spill on its own. The electric utility also wanted a pipe material that would be impervious to most of the chemicals with which it could come in contact, particularly oil, and they wanted a joining system that would not leak into the subsurface soils. They chose a design submitted by civil engineers at Davis-Martin-Powell & Associates (DMP) of High Point, N.C. Ben Palmer, P.E., the DMP engineer in charge of the project, worked with Don Joyce of Pomona Pipe Products, Greensboro, N.C., who suggested pipe materials for the project. Both Joyce and Palmer had experience with the joint and chemical resistance of Hobas pipe, and specified it based on that experience. Palmer’s plan to intercept the drainage system involved installing an oil stop valve that would be sensitive to the specific gravity of the liquid in the chamber.

Hobas pipe can be easily modified in the field. Here a worker cuts a hole to provide a connection for a smaller pipe.

Water inside this chamber would cause the valve to float, allowing the water to continue outward to public drainage. If oil

were sensed inside this chamber, the valve would not open because oil is less dense and lacks the buoyancy to lift the valve. “The bank of transformers is situated atop a rock field sump,” said Palmer. “The sump areas are connected to a storm drain pipe that conveys the stormwater runoff off-site and drains these sumps during a rainfall event.” The oil stop valve was installed inline on the storm drainpipe, leaving the site. Inside of the oil stop valve structure, a precast structure houses the oil stop valve along with a diversion pipe leading into the containment system. In the event that the valve sensed oil and remained closed, the oil-contaminated water would be funneled into an underground containment reservoir that was constructed of six-foot diameter pipe, where it would temporarily remain until it could be manually pumped out and properly disposed. “The design capacities for the two sites were based upon containment of a single piece of equipment and the rainfall from a 25-year, 24-hour storm event,” said Palmer. “The concept was very similar to an underground stormwater detention facility, just a different application.”

SAFEGUARDING The containment vessels are made up of custom-made elbows and tees to create manifolds and 90- to 104-foot long straight runs, according to Matt Swenson of Power Consulting LLC, the on-site inspector for the utility. The straight sections used were 20 feet long and weighed about 7,000 pounds. One substation’s containment vessel covers a footprint of 26 feet by 104 feet and is composed of 328 lineal feet of 72-inch pipe in three straight runs for a capacity of 60,750 gallons. The other 500-kV substation’s vessel covers a footprint of 36 feet by 90.25 feet with 383 lineal feet of 72-inch Hobas pipe in four straight runs for a capacity of 81,560 gallons. According to Joyce, the pipe had been pre-ordered and was onsite when the contractors arrived. The installation was performed by different contractors at the two different sites, neither of whom had prior experience with this pipe. Quartermaster Environmental, Shelby, N.C., installed one system and Willis Construction Co. installed the other. Each 72-inch pipe containment reservoir was installed in a 12-foot deep excavation atop a one-foot base of washed stone and topped with five to six feet of cover. There was a learning curve in handling and placing the sections, with correct placement being critical in order to make the straight runs and enable the manifolds to properly join at opposite ends, approximately 100 feet apart, according to Swenson. “As the contractor set each piece, they backfilled a portion to hold the pipe in place so that there would be no need for manipulation when tying into the manifold at the end of the run. “I feel both projects were a success and I understand that both are operating correctly now a year later, namely that they are dry.” PE Kimberly Paggioli, P.E., is vice president of marketing and quality assurance for Hobas Pipe USA. She can be reached at (800) 8567473 or [email protected]. Visit www. hobaspipe.com.

One of the straight stretches of Hobas is installed using an excavator. Lightweight Hobas pipe does not require the heavy machinery needed for concrete pipe. As the contractor set each piece, they backfilled a portion to hold the pipe in place and avoid the need for manipulation when tying into the manifold at the end of the run.

Picking an EPA Protocol Gas

O

ffered by a dozen or so suppliers, EPA protocol gases seem to grow on trees these days. But are they all the same? Not according to EPA blind audits in which historically close to 11% of EPA protocol gases analyzed fail to match the tag values for NO, SO2 and CO2. ACCURACY: EPA mandates that actual contents of a cylinder must be within 2% of what the cylinder’s Certificate indicates (tag value). Calibrating your CEM with an inaccurate mixture can result in either overstating or understating your emissions. If you overstate them, you can lose out on emission trade credits. If you understate them, suffice it to say EPA takes a dim view of understating emissions. BLENDING: Precision blending of mixtures was introduced over 20 years ago when Scott Specialty Gases invented ACUBLEND™. However “Acu-type” blending, from any vendor, is not much of a factor with EPA protocol mixtures. It’s the subsequent accurate analysis that proves challenging. ANALYSIS: It’s the most critical characteristic of any protocol blend, so be sure you understand how your cylinder was analyzed. Analytical methods and data should be clearly indicated on the cylinder’s certificate. Some suppliers use chromatographs instead of FTIR, which is preferable. Those who do use FTIR typically use stock models even though customized FTIR instruments provide more accurate analysis.

CERTIFICATE: A Certificate of Analysis should detail how your mixture was prepared. SCOTT™ brand mixtures are unique in that they ship with a Certificate of Accuracy, because the document exceeds EPA minimum requirements and details all preparation data necessary to validate the mixture’s guaranteed accuracy. Don’t lose the certificate for each cylinder on site. You must show them in the event of an audit. Using a supplier who makes cylinder certs available online can avoid misplaced documents. TRACEABILITY: Your certificate should indicate that your mixture was prepared using standards directly traceable to either a Standard Reference Material (SRM) or a NIST-Traceable Reference Material (NTRM). There are no substitutes. PRODUCTION SPEED: This directly impacts deliverability. The Solutions Center at Air Liquide frequently receives calls from companies unable to get a mixture from their regular supplier. So consider choosing a supplier who can routinely blend and ship a nonreactive in 10 days, and a reactive in 17 (EPA requires 7 calendar days between the first and second analysis for reactive mixtures). EPA PGVP: As of May 27, 2011, the owner or operator of a unit subject to Part 75 emissions monitoring that uses EPA protocol gases must procure the gases from a vendor whose production site for those products is a registered participant in the EPA Protocol Gas Verification Program. Existing EPA protocol gases already on site may be used until the cylinder expiration date is reached or the cylinder pressure reaches 150 psig, whichever occurs first. Be sure to choose EPA protocol gas from a supplier with EPA PGVP registered production sites. All Air Liquide America Specialty Gases EPA protocol production sites are registered participants. Our SCOTT brand RATA Class™ and Compliance Class™ EPA products that are produced in these facilities are certified to be manufactured in strict accordance with EPA protocol requirements.

fter working in the VOC control equipment sector since the early eighties, the founding employees of NESTEC Inc. learned what works when providing VOC Control equipment to industry. They founded NESTEC with intention of truly teaming with their customer to provide custom equipment solutions in today’s cost competitive environment. Seven years later NESTEC is providing OEM Equipment and aftermarket service to companies nationwide, ranging from Fortune 500 companies to privately held stand-alone facilities. NESTEC’s core expertise lies in thermal oxidation for VOC Control. The core group of employees possess more than 100 years combined experience in VOC Control equipment specification, design, fabrication, installation, and service. NESTEC provides a wide range of equipment including: • Regenerative thermal oxidizers (RTOs) – NESTEC designs and fabricates two-canister RTOs with airflows ranging from 1,000scfm to 80,000scfm, NESTEC provides a full range of options including forced or induced draft systems, ceramic media selected specifically for customers processes, and special materials of construction for corrosion protection. Our proprietary design allows us to guarantee 99% VOC destruction efficiency and 95% thermal efficiency with our two-chamber RTOs. • Regenerative catalytic oxidizers (RCOs) provide an effective method of reducing energy consumption while still retaining the system simplicity of a traditional RTO. • Recuperative thermal oxidizers (TOs) have been installed in airstreams where secondary energy is required. Using tube and shell heat exchangers they can be an effective alternative for silica containing manufacturing processes. • Catalytic oxidizers are simple cost-effective abatement solution for removing VOCs from stable, “clean” process exhaust, including some chemical manufacturing, printing, and baking processes. • Concentration systems provide a way to concentrate high-volume, lowconcentration processes to reduce both capital and operation costs, by concurrently reducing overall airflow and increasing the available residual energy in the exhaust to be oxidized, reducing any required fuel.

• Direct-fired oxidizers (DFTOs) are a simple robust system for intermittent or highly corrosive (halogenated) process air streams. The technical team works with customers to assess the process stream and develop and provide the most effective combination of capital cost, operating cost based on both energy use and operational maintenance requirements, and the performance required environmentally. Developing and designing the control equipment is often only half of the challenge. Effectively installing and integrating VOC Control equipment into an existing operating facility requires both experience and employees capable of quickly adapting and effectively working with plant personnel. NESTEC understands the requirement for minimized downtime during installation and start-up and teams with our customers to ensure field installation success. Over the course of thermal oxidation’s history in industrial America, many air pollution control companies, large and small, have left the marketplace. In their wake are hundreds of oxidizers, large and small, with effective useful life. NESTEC’s Aftermarket Services has the experience and capability to do service and maintenance work on these “orphan” legacy units, providing an important service to capital conscious manufacturers in the current competitive marketplace. NESTEC partners with our suppliers to ensure cost-competitive sourcing and fabrication of our components. Our technical team’s ability to work with multiple vendors and controls providers allows us to provide almost any option to a manufacturing facility. Standardizing on a component manufacturer, no problem… integrate, upgrade, or standardize your PLC controls, not a challenge.

F

or more than 16 years REGENESIS has provided the environmental community with the highest-quality remediation products and industry-leading technical support. The Company’s earliest product, Oxygen Release Compound (ORC®), revolutionized aerobic bioremediation of petroleum-based contaminants by providing a cost-effective, controlled-release peroxygen with 12 to 18 months of oxygen release on a single application. From that point forward, REGENESIS embraced the market’s demand for the need to treat a broad spectrum of contaminants and developed an entire suite of in situ remediation products for the lowcost and effective treatment of soil and groundwater. Today REGENESIS manufactures and supports a range of product based technologies, which are categorized into five specific groups:

Accelerated Aerobic Bioremediation • Oxygen Release Compound ADVANCED (ORC Advanced®) • Oxygen Release Compound (ORC®) ORC and ORC Advanced offer unmatched quality and longevity when it comes to oxygen release compounds, both have been proven on thousands of sites worldwide. Typically shipped as a powder, these materials can be mixed with water to form an injectable slurry and applied at pre-determined intervals targeting the main areas of contamination. They can also be applied into excavations, barriers or in filter sock form. Filter Socks are the original method of ORC application (a replaceable, sock-type fabric filled with ORC material that is easily emplaced in wells) and are still widely used today. Accelerated Anaerobic Bioremediation • 3-D Microemulsion® • Hydrogen Release Compound (HRC®) • Extended Hydrogen Release Compound (HRC-X®) • Hydrogen Release Compound PRIMER (HRC Primer®) REGENESIS’ soluble hydrogen sources offer class-leading quality and hydrogen production with a wide array of applications. These materials are typically shipped as a viscous liquid and injected at pre-determined intervals targeting the main areas of contamination. They can also be applied into excavations and barriers to cost-effectively enhance reductive dechlorination.

3-D Microemulsion is shipped as a concentrate then mixed with water on-site into a higher-volume, microemulsion form where it supplies a unique staged release of lactic acid and hydrogen for extended periods of time. Chemical Oxidation • RegenOx® Chemical Oxidation System RegenOx is an advanced, two-part, chemical oxidation system that upon injection creates a chemical reaction that destroys contaminants on contact. This product produces an oxidation reaction as effective as Fenton’s Reagent yet without a substantial exothermic reaction, making it safe and easy to handle. RegenOx is also compatible with bioremediation as its use often creates favorable conditions for follow-on aerobic biological remediation processes. Metals Immobilization • Metals Remediation Compound (MRC®) MRC is a unique product specifically designed for the treatment of chromium in groundwater and soil. Also delivered as a liquid, this material works by means of a proprietary binding agent and by promoting reducing conditions within groundwater. Bioaugmentation • Bio-Dechlor INOCULUM PLUS (BDI PLUS®) When faced with an insufficient quantity of critical dechlorinating microbes, BDI Plus supplies microbial degraders to the subsurface, including the Dehalococcoides (DHC) species, which is required to achieve complete and rapid dechlorination. BDI Plus is a microbial consortium proven to promote the complete degradation of chlorinated solvents such as cis-1,2dichloroethene and vinyl chloride.

ith the increasing need to contain and treat wastewater comes a growing requirement to pump unknown pollutants from collection pits and transfer corrosive chemicals to wastewater treatment areas. Caustic and acidic wastewater treatment chemicals commonly attack pumps constructed of stainless steel or high alloys – all of which have annual corrosion rates – and can cause plastic lined pumps to delaminate, and fiberglass pumps to wick the fluid. In many cases, wastewater containing abrasives, cause metal, lined-metal and fiberglass pumps to wear, compromising efficiency and longevity. Corrosion-related pump problems can be eliminated, says Vanton Pump, by isolating

the fluids being pumped, from any metal or fiberglass component. The company injection molds all wet end components of PVC (polyvinyl chloride), PP (polypropylene) and PVDF (polyvinylidene fluoride) which are abrasion resistant, and 100% inert relative to the fluid(s) being handled. The parts are molded thicksectioned, stand-alone, replaceable components, and have smooth, tight-tolerance surfaces. In addition, they are virtually unaffected by wear, and are not subject to delamination. All wetted components of Vanton's SUMP-GARD® Vertical Centrifugal Pumps are of solid thermoplastics to resist the broad range of chemicals that can enter a sump pit during its life, significantly reduc-

ing the possibility of pump failure. CHEM-GARD® horizontal centrifugal pumps feature thermoplastic wet ends encased by structural metal armor, enabling them to handle the same nozzle loadings as metal pumps.

The rugged construction is suitable for direct or panel mounting and gives readings that are independent of barometric pressure. Within the gauge is an evacuated and hermetically sealed aneroid capsule. Variation of pressure causes deformation of the capsule, and this movement is transferred to the pointer by a mechanical linkage with a jeweled movement. Since the gauge gives a direct pressure measurement, it is independent of the composition of gas or altitude.

The Dart system quickly identifies the presence of petroleum, coal tar or creosote NAPLs in sediments and soft soils. The system reduces the time and cost of locating contamination, and can be deployed in areas where mechanized soilboring techniques are not practical or feasible. The probes can be inserted into a shoreline or sediment under an adjacent water body. The special solid-phase extraction coating will sorb any existing PAHs over a 24 to 48 hour period for evaluation at the jobsite with laser-induced fluorescence.

With the sensor’s high tolerance for a broad range of temperatures, humidity levels and shortterm high H2S concentrations, the gas sensor is ideal for use in oil and gas applications, chemical plants or a variety of other important industrial applications.

Product Focus: Chemicals Portable Emission Testing The company introduced three highspeed PULSAtron A Plus series products. The products were extensively tested to deliver performance in the most demanding a p p l i ca t i o n s . Maximum stroke speed is doubled to reach 250 strokes per minute to provide greater flow at higher pressures. The new models use the same KOPkits as before. Optional control features of external pace and external stop are available throughout the line, but for something special, the new sizes also have a 1,000:1 turndown ratio option for more demanding metering applications.

Baghouse Leak Detector The company has launched the CCP Series Tank-Tite Compression Fittings for bulkhead fittings and tank accessories. The PVC fittings provide a constant load on the bulkhead gasket to overcome and compensate for tank wall expansion/contraction due to changes in temperature and/or pressure within the tank. It also imparts a constant load on the bulkheadfitting nut to reduce the possibility of loosening due to vibration. Typical applications or installations include water and wastewater treatment, chemical processing, food & beverage, marine or corrosive environments, metal finishing/plating, and agriculture/irrigation.

AL – NEW STORMWATER CONSTRUCTION GP

The DEM released a new Construction General Permit. The permit applies to discharges from construction activities that result in a total land disturbance of one acre or greater and sites less than one acre but are part of a larger common plan or development. Officials said that the GP will replace the permit-by-rule program. The effective date of the GP was April 1, 2011.

IL – PERC BANNED

The state seeks to become the second to phase out the use of perchloroethylene (perc) in dry cleaning. Beginning in 2030, Senate Bill (SB) 1617 prohibits the use of perc, a VOC that has been detected in groundwater and in community drinking water systems. Under the bill, new fourth- and fifth-generation equipment could continue to be sold for as long as perc is permitted in the state. Third-generation equipment could continue in operation only for the remainder of its useful life and only in the facility where it is located.

KY – SIP MAINTENANCE PLANS APPROVED

Effective May 16, 2011, the EPA approved revisions to the state’s SIP that include maintenance plans addressing the 1997 8-hour ozone NAAQS for four state attainment areas: Edmonson County; the portion of Greenup County that was previously a part of the Huntington-Ashland, West Virginia-Kentucky 1-hour ozone maintenance area; Fayette and Scott counties; and Hancock County and

42 PLE01094Airg.indd Pollution Engineering JULY2011 1

the portion of Daviess County that was previously a part of the Owensboro 1-hour ozone maintenance area. These were 1-hour ozone maintenance areas that were designated as attainment areas for the 1997 8-hour ozone NAAQS.

MI –PESTICIDES NPDES POSTPONED

The DEQ said it has postponed implementation of the new NPDES permit slated for implementation this year. As such, pesticide applicators in the state will continue operating this season under existing guidelines. Extended federal court cases, continued language revisions to the new permit system, and uncertainty surrounding the fate of the NPDES pesticide permitting program in general were contributing factors.

5

NH –REPEALS GHG CAP AND TRADE

The state’s House of Representatives passed HB 519 that would repeal the regional greenhouse gas (GHG) initiative cap and trade program for controlling CO2 emissions. HB 519 also clarifies how the monies in the GHG emissions reduction fund may be used. The bill is currently being considered by the Senate’s Energy and Natural Resources Committee.

6

OH – SHOPPING FOR BROWNFIELDS

The state EPA recently announced the availability of an online brownfields database that lists abandoned, idle

or underutilized industrial properties that are ready for redevelopment. The goal is that the online tool would help businesses identify and evaluate potential properties, and help communities promote redevelopment of local brownfield sites.

7

TX – TITLE V FEES TO RISE

The state CEQ proposed raising emissions fees for Title V sources. The proposed amendment would increase the base rate for such fees from $25 to $35 per ton or as needed and allow annual adjustments up to a cap of $45.

UT – DEQ CONSOLIDATES ADMINISTRATIVE RULES

The state DEQ is consolidating its administrative procedures into one rule. State law requires the DEQ to use administrative law judges for most administrative proceedings. Many of the updates are needed to incorporate that statutory change. Rule updates also make clarifications and improvements in administrative procedures. The purpose of specifying administrative procedures is to ensure participants have information about how proceedings will be conducted and ensure they are conducted fairly and efficiently. Future rules will repeal the current rules and change references to the new rule. This update is provided by Business & Legal Reports Inc., practical EHS publishers since 1977.
