When do the costs of environmental regulation actually exceed the benefits?

T

he comedy duo of Laurel and Hardy may not be remembered by many in this generation but they once led audiences to thunderous laughter and applause when they appeared on the silver screen in the 1920s. In nearly every one of their movies, Oliver Hardy’s most famous line was used whenever he would lash out at the lanky Stan Laurel and proclaim, “this is another fine mess you have gotten me into.” About a year ago, President Obama issued an Executive Order to all of his agencies to review their regulations and decide which were costing too much money without offering many benefits. EPA has taken much criticism from industry for costly regulations that not only damages their bottom lines but also results in less monetary assets that can be used for future investment in human resources. The agency did release a list of regulations they thought could be shelved to save money. However, industry pundits soundly criticized them as being too few and unaccommodating. A few weeks ago, Obama released a statement that his office was ordering the agency to shelve its recent ozone standards until further studies were completed. Just a week later, EPA released a press release that they were still approving the new standards for an area in California. Currently, the regulation of emissions that cross state borders is a significant air issue that cannot be ignored. The Clean Air Interstate Rule (CAIR) attempted to address this issue. The rule was challenged for years in the courts and, in 2008, the courts ordered EPA to develop new regulations. EPA was ordered to maintain CAIR until new regulations were approved. The effort resulted in a regulation that the agency calls the Cross-State Air Pollution Rule (CSAPR), which the industry immediately dubbed the “Casper rule.” The rule,

which primarily targets emissions from coal-fired power plants, is scheduled to begin implementation in January. According to EPA, the rule is expected to cost industry about $800 million per year, as well as $1.6 billion in annual capitol expenditures. However, they also forecast the rule will yield health savings benefits of $120 to $280 billion per year by 2014, while also reducing health and environmental costs. Meanwhile, Energy Future Holdings Corp. is taking a different approach to EPA’s suggestion. They have filed a lawsuit that challenges the agency rule, claiming the costs are too prohibitive at an estimated $1.5 billion per year through 2020; 500 industry jobs may also be lost. They are asking the courts to stop the implementation of the rule until a more complete study can be conducted. Their claim is that they would be forced to shutter 1,200 megawatts of power generation and halt all mining operations that provide coal to those plants. They said they were already looking to spend $280 million by the end of 2012 and $1.5 billion by 2020. Any additional costs would likely be devastating to the company. They also objected to the agency’s plan to add Texas plants to the new rule as previous versions of the regulations had excluded the state. On the face of the argument, the returns seem to be worth the investment. Two questions come to mind though. First, can we afford to spend this much right now? Also, are the returns even real? PE

EPA Proposes To Revise Tier I and II Forms The EPA is seeking comments in regards to its proposal to eventually revise information to the Tier I and Tier II forms that businesses are required to submit each year. On Aug. 8, 2011, the EPA proposed to revise the Emergency and Hazardous Chemical Inventory Forms (Tier I and Tier II), under Section 312 of the Emergency Planning and Community Rightto-Know Act (EPCRA), to add new data elements and to revise some existing data elements. Under the proposal, the EPA is seeking the following changes: add new data elements for facility phone numbers, as well as latitudes, longitudes and numbers of full-time employees; add data elements for facility identification numbers that are assigned under the Risk Management Program, which is implemented either under Section 112(r) of the Clean Air Act (CAA) or the TRI Program under EPCRA Section 313, and require facilities to provide information on the facility’s parent company and the owner or operator of the facility, such as name, address, and phone number, as well as the Dun and Bradstreet number of the facility’s parent company. In addition, the EPA desires further changes, including providing the name and contact information of a facility representative, who will participate in the emergency planning process as a facility emergency coordinator, to the local emergency planning committee (LEPC); requiring facilities to notify LEPCs of any changes relevant to the emergency planning within 30 days (the agency believes this information should also be provided on the facility’s annual inventory form since LEPCs and other emergency response coordinators may need this information during an emergency) and requiring the name, title, phone number, and e-mail address of the person knowledgeable or responsible for completing the information on the Tier I and Tier II forms. The EPA also wants to implement three more changes, including adding a new data element to indicate if facilities are subject to the emergency planning notification under EPCRA Section 302; adding a new data element to both the Tier I and Tier II forms to indicate whether the facility is subject to chemical accident prevention under CAA Section 112 and expanding the ranges for the reporting codes for the maximum amount,

AIR EPA Accepts First GHG Reporting Data The EPA announced that it has launched a new tool to allow 28 industrial sectors to submit their 2010 greenhouse gas

(GHG) pollution data electronically. Prior to being finalized, more than 1,000 stakeholders, including industry associations, states and NGOs, tested the electronic GHG Reporting Tool (e-GGRT) to ensure clarity and user-friendliness. All data collected with e-GGRT will provide the public with important information about the nation’s largest stationary sources of GHG pollution. Industries and businesses can also use the data to ultimately decrease carbon pollution, increase efficiency and save money. The EPA expects to receive 2010 GHG data from approximately 7,000 large industrial GHG emitters and suppliers, including power plants, petroleum refineries and landfills. EPA’s GHG Reporting Program, launched in October 2009, requires GHG data from large emission sources to be recorded across a range of industry sectors. Suppliers of products that would emit GHGs if released, combusted or oxidized are also required to report GHG data. Under this program, covered entities are required to submit GHG data annually to the EPA; the first round of data will be submitted electronically by Sept. 30, 2011. The agency plans to publish non-confidential GHG data that is collected through the GHGRP by the end of 2011. For more information on the GHG Reporting Program, visit the following link on EPA’s website: www.epa.gov/climatechange/emissions/ghgrulemaking.html.

EPA Fugitive Slapped with Seven Years The former owner of the country’s largest asbestos abatement training school was sentenced to prison, after having fled the United States following her trial in November 2008. U.S. District Judge Nathaniel M. Gorton sentenced Albania Deleon, 41, formerly of Andover, Mass., to 87 months in prison, which will be followed by three years of supervised release. She was also ordered to pay more than $1.2 million in restitution to the IRS and $369,015 to AIM Mutual Insurance Company. No level of exposure to asbestos is safe; any removal by untrained workers, performed without the necessary safeguards, threatens the health of those workers and the public. In November 2008, following a three-week trial, Deleon was convicted of a broad range of charges, including the sale of training certificates to thousands of illegal aliens who had not taken the mandatory training course. Deleon then placed these unqualified individuals in temporary employment positions as certified asbestos abatement workers; for months, they served in public buildings throughout New England. Deleon

ENVIRONEWS was also convicted of encouraging illegal aliens to reside in the United States; making false statements about matters within the jurisdiction of the Environmental Protection Agency (EPA); procuring false payroll tax returns and mail fraud. “Today, justice was served, and Albania Deleon has finally faced the consequences of her crimes. I hope that this sentence sends a strong message to anyone who might contemplate fleeing to avoid punishment, that we do not give up on fugitives, and we will take all necessary means and resources to apprehend and prosecute them,” said United States Attorney Carmen M. Ortiz.

ENVIRONEWS WASTE EPA Excludes Carbon Dioxide as Haz Waste The EPA is proposing to revise the regulations for hazardous waste management, which are included in the Resource Conservation and Recovery Act (RCRA), to conditionally exclude CO2 streams that are hazardous from the definition of hazardous waste, provided these hazardous CO2 streams are captured from emission sources, are injected into Class VI Underground Injection Control (UIC) wells for purposes of geologic sequestration (GS) and meet certain other conditions. The EPA is revising these regulations because it believes the management of these CO2 streams under the proposed conditions does not present a substantial risk to human health or the environment, and therefore, additional regulation pursuant to RCRA’s hazardous waste regulations is unnecessary. The agency believes this amendment will substantially reduce the uncertainty associated with identifying these CO2 streams under RCRA subtitle C, and will also facilitate the deployment of GS by providing additional regulatory certainty. Comments must be received on or before Oct. 7, 2011.

EPA Modifies Chemical Data Reporting Rule New reporting requirements will lead to novel definitions and, ultimately, further attention to details. n Aug. 2, 2011, EPA released the final Toxic Substances Control Act (TSCA) Chemical Data Reporting (CDR) Rule, which was previously referred to as the Inventory Update Reporting (IUR) Modifications Rule.

O

Background For years, EPA has continued to revise TSCA Section 8 IUR reporting so that it would provide more detailed chemical production, processing and use information. Earlier this year, as the IUR reporting cycle ended, EPA suspended the reporting requirement, pending issuance of the final rule. The final rule, which was released on Aug. 2, 2011, did not offer any surprises, and EPA properly balanced a variety of significantly disparate views regarding the ways in which it should have modified the rule. The CDR Rule will be effective 30 days after its publication in the Federal Register. For more information, please visit http://www.epa.gov/cdr/.

Key provisions The name was changed from IUR to CDR in order to reflect the distinction between subsequent data collections and the TSCA Inventory itself. Who Is Required to Report? EPA states that entities may be affected by the CDR Rule if they manufacture (manufacture can mean byproduct or import) for commercial purposes, chemical substances, listed on the TSCA Inventory and produced in volumes of 25,000 lbs. or more at a site during the principal reporting year. At the same time, EPA’s definitions of and interpretative guidance statements on words such as “manufacture” and “byproduct” may sigwww.regulations. nificantly impact certain industries. gov/#!docketDe The agency said that it is currently tail;dct=FR+PR+ N+O+SR;rpp=10; providing “additional information on po=0;D=EPA-HQbyproduct reporting” because “the OPPT-2009-0187

scope of the CDR obligation to report byproducts is not well understood by industry.” EPA’s guidance and interpretation of byproducts raises many concerns, including possible notice issues, and it is not apparent whether certain byproducts should be listed on the TSCA Inventory and/or subject to CDR reporting. It is also unclear that EPA has interpreted such terms consistently. When Is Reporting Required? The 2012 submission period, during which 2011 manufacturing, processing and use, as well as 2010 production volume information, would be reported, is scheduled to occur from Feb. 1, 2012 to June 30, 2012. Subsequent recurring submission periods will last from June 1 to Sept. 30 at four-year intervals, beginning in 2016. What Will Change for 2012? Manufacturers, including importers, are obliged to report the production volume of a chemical substance that meets or exceeds the 25,000 lb. threshold per site during the principal reporting year. They are also required to provide upfront substantiation for each data element that is claimed as confidential business information. EPA said that submitters cannot claim data elements as confidential if they are identified as “not known to or reasonably ascertainable by.” Submitters are required to use e-CDRweb, which is EPA’s electronic reporting tool. What Changes are Planned for the 2016 CDR? EPA is

delaying implementation of certain requirements until the 2016 submission period. For the 2016 CDR, the agency will determine if it needs to report further findings, for any calendar year since the last principal reporting year, according to the size and types of chemical substances that are manufactured and imported; if substances are manufactured in volumes of 25,000 lbs. or greater, the agency will likely report such importation. EPA will provide guidance materials with reporting instructions, questions and answers, and case studies prior to the start of the submission period. The agency has also developed two documents to provide detailed instructions for reporting.

Regenerative

TURBINE Aeration TECHNOLOGY By applying the laws of physics while regularly utilizing properly sized bubbles, managers and technicians can achieve consistent wastewater treatment system results. By STUART WARD, General Manager of Process Engineered Water Equipment

I

n order to acquire precise control of input and output fluid/gas parameters, wastewater managers and technicians can utilize a regenerative turbine pump, which fully optimizes the gas dissolution process that properly treats wastewater, time after time. Once such parameters have been completely controlled, a well-designed wastewater treatment system should be able to initiate all necessary operating duties after each start-up. To enlighten wastewater professionals as they discover and use such gas-dissolving technology, this feature will focus on the various potential benefits that regenerative turbine technology may offer.

Gas dissolution and regenerative turbines During the first step of the regenerative turbine process, gas is dissolved into a fluid solution through the application of a predetermined amount of pressure. The regenerative turbine pump applies such pressure, through a combined triple-action force (centrifugal, axial and friction), to the gas and fluid during a single pass through the pump head. Whether dissolving compressed or atmospheric air, nitrogen or other gasses to the fluid, the regenerative turbine pump

will always achieve the highest possible saturation level at a given temperature.

Gas solubility air example A common application for such pump technology is the dissolution of air into water. The volume of air that can be dissolved in water increases with the system pressure and decreases as the temperature lowers. While using air as an example, regenerative turbine pump gas dissolution can be calculated. The solubility of air in water can be expressed as a solubility ratio. Sa = ma / mw Where: Sa = solubility ratio ma = mass of air (lbm, kg) mw = mass of water (lbm, kg)

Solubility: Henry’s Law Meanwhile, Henry’s Law states that “the amount of air dissolved in a fluid is proportional with the pressure of the system.” Therefore, while fully utilizing Henry’s Law, the following symbols will be used: c = pg / kH Where: c = solubility of dissolved gas kH = proportionality constant depending on the nature of the gas and the fluid

pg = partial pressure of the gas Please note that the solubility of oxygen in water is higher than the solubility of nitrogen. Air that is dissolved in water contains approximately 35.6 percent oxygen; in comparison, ambient air only contains 21 percent oxygen.

Solubility calculation According to Henry’s Law, at a system temperature of 77°F the volume of air dissolved in water can be calculated as: Oxygen as O2 : 756.7 atm/(mol/liter) Nitrogen as N2 : 1600 atm/(mol/liter) Molar Weights: O2 is 31.9988 g/mol N2 is 28.0134 g/mol Partial Fraction in Air: O2 is about 0.21 N2 is about 0.79 The O2, which is dissolved in the water at atmospheric pressure, can be calculated as: co = (1 atm) 0.21 / (756.7 atm/(mol/ liter)) (31.9988 g/mol)= 0.0089 g/liter, ~ 0.0089 g/kg The N2, which is also dissolved in the water at atmospheric pressure, can be calculated as:

TURBINE Aeration

cn = (1 atm) 0.79 / (1600 atm/(mol/ liter)) (28.0134 g/mol) = 0.0138 g/liter, ~ 0.0138 g/kg Since air is the sum of nitrogen and oxygen, the following results can be obtained: ca = (0.0089 g/liter) + (0.0138 g/liter) = 0.0227 g/liter ~ 0.023 g/kg By applying such results to the regenerative turbine pump, a performance curve can be graphed. Note that the gas dissolution for air peaks at 10 percent by volume given normal system operating conditions with temperatures that do not exceed 100°F. The regenerative turbine pump discharge pressure meets or exceeds discharge requirements for most dissolved air flotation (DAF)

• Provides high efficiency without causing cavitation. • Presents safety and control features that assure reliability.

Design and applications Typically, a regenerative turbine pump is sized in saturation applications to just 20 percent of the total system flow. Therefore, the pumps are well suited for DAF membrane and oil recovery systems. Wastewater technicians will recognize that these pumps are useful in the food and beverage, laundry, pulp and paper, brewery and petroleum industries. Through further observation, they will also realize there are many other special process applications available as well.

requirements. Such a design optimizes the fluid pumping dynamics within the interior passageway to improve the efficiency and overall pressure that users hope to achieve. Consequently, near complete dissolution of entrained gasses can be acquired at the highest volume possible during the pump cycle. This process is completed during a single pass, which leads to minimized horsepower requirements.

Impeller tuning Each regenerative turbine impeller has a profile that is uniquely performance tuned. Tuning is based on engineered and field testing by optimizing the width and length of the impeller vanes. To efficiently

Why change? Of course, wastewater managers and technicians may use several older technological options as well in order to dissolve gasses into a liquid. In comparison to other options, the pump offers a competitive alternative for the following reasons: • Generates 20 to 30 micron sized bubbles. • Consumes less energy. • Dissolves gas at modest pressures. • Offers users a low wear pump fluid interface. • Utilizes a simple design that is easy to implement. 20

Close coupled pump can lower flows. Flex coupled pump provides higher flows.

Pump features Regenerative turbine pumps also have a robust construction. According to the list below, managers and technicians may consider the following reference points as they determine which quality pump design they will actually choose: • Materials: stainless steel, iron, brass • Close and flex-coupled models • May be mounted in many locations • Capacities of five to more than 120 GPM • Pump heads in excess of 200 feet • Economical seals

dissolve gas into the fluid, horsepower must be reduced; such reduction usually improves off-peak horsepower requirements as well.

Blade efficiency Impellers are built with blade profiles and counts, which have been engineered for their particular fluid passageway crosssections. Impeller blade counts increase efficiency without leading to complex blade contours. Thus, the regenerative turbine pump yields high-performance characteristics that typically exceed those of more expensive units.

Hydraulic design Regenerative turbine pumps can also be offered in single- or dual-impeller mechanical units. The internal hydraulic cavity is engineered to achieve maximum capacity and pressure while minimizing horsepower

Adding it up While examining the air solubility calculations and also applying the regenerative turbine pump design, it appears that the results are within the expected

efficiency range. Each of these results can be verified by using an air rotometer indicator, which should match the calculated volume. Accordingly, the net result equals a dissolved air release with 20 to 30 micron bubbles. Picture 4 vividly illustrates those bubbles within a DAF vessel; such bubbles are often referred to as “whitewater.” Picture 2

Setting up gas dissolution systems Wastewater technicians should select pumps and piping materials according to the fluid type and temperature they expect to encounter. Operators must have full control of the system, as well as all builtin automatic safety features. The system should be also piped so that saturation time is maximized. The regenerative turbine pump ought to also match the overall system flow and hydraulic capacity. Of equal importance, technicians should also consider the following system limitations: Discharge Pressure 125 psi Seal Pressure 200 psi Suction Vacuum 26 inches Hg Speed (Flex) 1,750 rpm Speed (Close) 3,450 rpm Temperature -20°F to 150°F

System components A well-designed gas dissolution system will also have a number of components beyond just the pump itself. These items, which are usually either schedule 80 PVC or stainless steel, include the following:

Example setup The following pictures illustrate a typical DAF system upgrade. In Picture 1, a regenerative turbine pump is fed clarified effluent water through a control valve with air injected via an acrylic rotometer. A slight vacuum is applied when atmospheric air is utilized. Wastewater technicians may find more controllable results by using compressed air pressures that range from 10 to 20 psi. Such pressures assure a more even flow and discourage fouling of the airline and rotometer. In Picture

2, a 125-psi safety and pump discharge pressure gage are shown. In Picture 3, the whitewater is introduced to the incoming system flow.

Regenerative turbine results As a result of these efforts, a fully operable gas dissolution system can be developed. Over time, treatment operators will discover that they not only have a low maintenance unit, but reliable efficiency as well. Picture 4 shows the whitewater that

is produced by 20 to 30 super saturated micron bubbles, as well as the formation of a dry sludge layer on the surface of the water. The final results are depicted in Picture 5 with the spillage of clarified water over the DAF effluent weir. PE Stuart Ward is the general manager for Process Engineered Water Equipment LLC.

Treating a CVOCS Groundwater Plume Using Multiple Reductive PRBs in Brazil

ADVERTORIAL

The Authors: Sidney Aluani, Eduardo Pujol, Fabiola Tomiatti and Ricardo Martini of SGW Services, São Paulo, Brazil Jim Mueller and Alan Seech of The Adventus Group, USA Josephine Molin and Edson Marcus Bucci of Adventus Brasil, Brazil Background: Groundwater at an active industrial facility in São Paulo, Brazil, is impacted with CVOCs, including chlorinated ethenes, ethanes and methanes. There are two separate plume areas: the first measures 50 m long by 50 m wide by 4 m deep (from 14 to 18 mbgs) with baseline total CVOCs concentrations up to 7,926 μg/L; the second plume measures 180 m long x 100 m wide x 5 m deep (from 18 to 23 mbgs) with baseline total CVOCs concentrations up to 1,099 μg/L and lower levels of zinc and cobalt.

adjacent coastline and access was therefore restricted in some areas. Silt is the predominant lithology and the linear groundwater velocity has been estimated at 18 m/year. Groundwater level varied across the site from 10 to 20 mbgs. Baseline conditions were relatively oxic with a DO of 1.2 to 5.1 mg/L and ORP generally ranging from 100 to 130 mV. Groundwater pH ranged from 4.6 to 6.7. The goal is to treat the CVOCs without mobilizing metals present in the soil. Challenge: The coastline is an environmental protection area, next to the city water supply source. In this particular area, the organic matter is high. Remediation Approach: Considering the plume extent areas, access restrictions and relatively low concentrations, a passive treatment approach using multiple Permeable Reactive Barriers (PRBs) was selected. The PRBs were installed across the plume areas via injection of EHC® to promote In Situ Chemical

Site Characteristics: The site heavily slopes towards the

Reduction (ISCR). EHC is a solid amendment composed of controlledrelease, complex organic carbon plus ZVI that quickly establishes reducing conditions and promotes abiotic and biotic degradation of CVOCs. EHC was injected as slurry via direct push in December 2009. Very limited access areas required manual application. Results: Subsequent performance monitoring conducted in January, February, March and April 2010 showed up to 99.8% total CVOCs removal measured within the PRBs. Results in downgradient wells vary with distance from the PRBs. In Area 1 Plume, the average CVOC concentrations measured within the targeted area decreased by 90% in 120 days (from a baseline of 2,823 μg/L to a current average of 289 μg/L). In Area 2 Plume, the remedial goals have been met in 6 out of 8 wells, however, concentrations remain unchanged in two of the central wells. The PRBs were spaced between 25 to 90 m apart based on access; therefore, considering a linear groundwater velocity of 18 m/

year, complete plume cleanup would be expected first after approximately 5 years. Continued monitoring is expected to show a decrease in CVOCs in downgradient wells.

Chemical Range Above is a cut away view of the Vanton Chem-Gard CGA unit used in the project.

By KENNETH COMERFORD, Vice President of Vanton Pump and Equipment Corp.

The system primarily handles acidic and alkaline waste streams at a petrochemical plant located in Neijing, China. s the designers of a sophisticated petrochemical manufacturing plant in Neijing, China began to develop an environmentally safe, minimum maintenance, and versatile neutralizing system, they encountered certain requirements that would ultimately need to be fully implemented. First, the system would need to handle corrosive and hazardous acidic and alkaline chemical waste fluids. Also, each of the fluids would have to regularly endure a harsh outdoor environment. As a result of such demands, the designers decided to utilize the expertise of well-experienced engineers at Digital Analysis Corporation, which is located in Skaneateles, N.Y. The corporation provided is specifically comprised of specialists who design packaged and customized pH adjustment systems for worldwide organizations.

A

The criteria for the proposed pH adjustment systems include each of these difficult fluid-handling scenarios: • The system’s flow must average 50 GPM (11 m3/h), with a peak flow of 100 GPM (23 m3/h); • The pH should range from highly acidic (0.5) to highly alkaline (13.0); • Temperatures could fluctuate from 50°F (10°C) to 150°F (66°C); • Total suspended small solids (salt precipitates) can be as high as 5,000 mg/L The original specifications for this system indicated the usage of type 304 stainless steel. Based on more than 20 years of experience using highly corrosive fluids in industrial processes, the engineers designing the system concluded that the recommended metal would not be suitable, and that the use of higher alloy materials or exotic metals was problematic and costly. Instead, they suggested to selectively use diverse thermoplastics for the pumps, pip-

ing, tank and other fluid-handling components. They then implemented each of these specific recommendations: a) Polypropylene for the four horizontal centrifugal pumps. The designers selected Vanton Chem-Gard CGA units that included all fluid contact components (casing, flanges and impellers); the components were furnished in solid, virgin polypropylene and met both ANSI B73.1 and international process pump standards (see Figure 1). b) Polypropylene for the customerfabricated treatment tank. Epoxycoated steel reinforcement ribs were encapsulated in polypropylene and incorporated around the perimeter of the tank to provide additional wall support. c) Chlorinated polyvinyl chloride (CPVC). The CPVC would be used for all of the pipes and fittings.

Above is a photograph of the spent chemical pH neutralization system That was designed for this project.

According to Richard Pinkowski, CEO of Digital Analysis, “in the opinion of our engineering department, since this application involved exposure to both highly acidic and highly alkaline discharge flows, and subjection to sudden temperature and pH changes, as well as harsh outdoor conditions, no other materials of construction would offer the long term reliability, safety and minimum maintenance required.” The installed system can rapidly neutralize hot caustic concentrations – as high as five percent in a brief period of time – and can handle 98 percent sulfuric acid as it is injected into the caustic stream, which undergoes rapid and significant temperature elevation. This spent chemical neutralization system can also be supplied as a completely fabricated, skid-mounted turnkey package (see Figure 2).

Process Cooling of Engine/Generator Sets with Reuse Water WWTP Produces Electricity While Saving Enough Potable Water in Cooling Process to Supply 500 Area Homes By Dr. Marcus N. Allhands, PE, Vice President of Business Development, Orival, Inc.

One of several municipal waste water treatment plants (WWTP) in St. Louis is located along the banks of one of the largest tributaries to the Mississippi River. This 100 MGD (million gallons per day) facility has a large demand for service water with low suspended solids. Nearly 3 MGD of water are needed for various on-site services but perhaps none as important as cooling large V-12 internal combustion engine/generator sets (Figure 1). These engines run off of methane gas produced on-site from the anaerobic sludge digestion process. The cooling process passes water one time through the engine blocks and then discharges the water back to the head of the WWTP. Therefore, this cooling water must be free of organic and inorganic particles that could interfere with heat transfer at the engine wall/water interface. The power produced by these engines can supply nearly all the electricity needed to run the entire wastewater treatment plant. However, if the engines overheat, safety controls shut down the engines and stop electricity production until the cooling problem can be solved. This immediately switches all power necessary to run the myriad of motors on pumps, aeration blowers, sludge presses and automated treatment equipment to purchased electricity. If this cooling process were to use potable water, as in many other facilities, the cost of this cooling water would nearly offset the savings of on-site power generation. An automatic self-cleaning screen filtration system provided by Orival, Inc. was installed recently using effluent from the wastewater treatment process for this non-potable cooling requirement saving enough potable water each day to supply an additional 500 homes in the area.

About Orival, Inc.: Orival filters have been installed on process cooling applications worldwide for over twenty years. Industries such as Petrochemical, Food & Beverage, Steel, Mining, Automotive, Paper, Power Generation and Ethanol production are just a few industries using Orival filters for water treatment in process cooling systems. Orival, Inc. provides a complete line of automatic self-cleaning filtration systems with sizes ranging from ¾” to 24” and filtration degrees from 3000 microns down to 10 microns. Orival filters are used to protect cooling towers, chillers, membrane systems, heat exchangers, spray systems, furnaces, internal combustion engines, mold jackets and more. Please visit www.orival.com or contact us by emailing [email protected] or by calling (800) 5679767.

Figure 2 shows the operating installation of the reuse system provided by Orival, Inc. as a complete package with filters, controls, manifold and valves. The controller initiates a cleaning cycle when a preset pressure loss occurs across the filtration system or by a manually set timer in the control panel. The pressure in the filter rinse chamber is greatly reduced by opening a valve to atmospheric pressure. The differential pressure between the water being pumped through the filtration system and atmospheric pressure causes a high velocity flow of water to pass through the screen cleaning mechanism called the dirt collector. The dirt collector rotates and moves linearly using the hydraulics of the water flowing in the system. This mechanism thoroughly vacuums debris from every square inch of the screen’s surface in less than 15 seconds without interrupting the filtration process. There have been no engine cooling problems since the Orival automatic filtration water reuse system began operating.

Heavy Metals By ROB ALDAVE, President of Valkyrie Environmental Water and STEVEN BUDAY, Technical Manager for Plymouth Technology Inc.

Copper is increasingly becoming a heavy metal of concern. A new technology was recently developed to handle it without chemicals or pretreatment. eavy-metal residuals in cooling tower blowdowns are quickly becoming an issue of great concern for nationwide industrial manufacturers and utilities. One of the common metals of concern is copper, which can be released as a result of metal corrosion in the cooling tower system (pumps, condenser coils, heat exchanger surfaces, etc.) and can be contained in biocides such as isothiazoline. Residuals of copper tend to be low, but are concentrated by cycling the cooling tower water. Federal and state regulators continue to lower the levels of copper that can be discharged to surface waters. Multiple users are now being held to allowable discharge limits of less than 10 μg/L. Additionally, local municipalities are concerned about the impact that copper from cooling tower discharges have on sanitary sewer systems. One municipality recently completed a survey that found an estimated six percent of the copper that is delivered to the Publicly Owned Treatment Works (POTW) is actually from cooling tower discharges. Consequently, Valkyrie Environmental Water, Rochester Hills, Mich., was asked to remove copper from a cooling tower blowdown by a Midwestern coal-fired power plant. The plant was preparing for a new copper permit discharge limit of 12 μg/L (reported as a monthly average). The cooling system had a copper throw that averaged more than 70 μg/L in the blowdown. The utility had been using surface water for cooling tower makeup with a copper background that ranged from nine to 20 μg/L. At that level, the tower could not achieve two cycles and maintain compliance. Even with once-through cooling, the inbound water still would not have always complied with the new permit limits.

REMOVING

Several options, including the following, were reviewed prior to removing copper from the water: • Membrane Filtration. Some operators may apply RO or UF membranes to remove copper. This technology has been demonstrated to produce good quality effluent, but it also creates a concentrated waste stream that must be treated with a physical or chemical process to precipitate the copper. Typically, additional chemistry is needed to remove any oxidants, such as chlorine or bromine, which can degrade the membranes and may require reduction with carbon or bisulfite prior to the membrane treatment. • Physical or Chemical Removal. Traditional hydroxide precipitation methods to remove dissolved copper can be applied. This method is chemistry intensive as it requires clarification aids, flocculants, pH adjustment and metal precipitants. In addition to the chemistry and equipment handling needs and sludge that will be generated, this method does not always consistently meet discharge requirements regarding low ppb discharge levels. • Ion Exchange. Several ion exchange resins can decrease copper concentrations to required discharge limits by using technology such as chelation or weak acid cation (WAC) resins. However, calcium or magnesium will compete with WAC resins. On the other hand, chelating resins do not compete with calcium or magnesium, but require a low pH (4.0 is typical) for optimal functionality. Most users would then need to lower the pH ahead of the resin and then increase it to meet discharge permit requirements. When the resins are exhausted, they will need to be regenerated. The regeneration process will create a concentrated waste stream, which will then need to be removed or treated. • Cooling Equipment Modification. By changing the metallurgy of heat

exchanger surfaces to low copper metals – such as stainless steel – facilities can decrease the copper concentration in the discharge. Still, this process requires significant capital investment and potential downtime for installation.

• Cooling Tower Operation Modification. By decreasing the cycles of operation, the inbound copper will be at a lower level in the blowdown. Yet, the contribution of copper corrosion is not considered during this process. Also, this method generally increases water usage.

Each of the above choices had drawbacks, such as the creation of a significant waste stream, which have required either a significant application of chemistry or a major capital expense. Due to the plant’s high flow rate of 7,000 gallons per minute, the operators did not want to adjust pH or add any precipitation chemistry. An alternative choice to the traditional methods mentioned was actually chosen for the pilot study. An adsorption system of three pressure vessels was set up in series and each was loaded with proprietary metals removal media. The approach utilized an adsorptive media that was comprised of organic and inorganic crystals. The media (in this case actiVE V-100) was chosen due to its high affinity and capacity for copper. Once adsorbed, the copper becomes part of the crystal structure of the media. The media does not require regeneration. As such, the media typically will pass a toxicity characteristic leaching procedure

(TCLP) as required by the EPA; in doing so, the metals will qualify for disposal as non-hazardous solids. Common cations, such as sodium, calcium or magnesium, are pass-through ions and do not react with the media. The average removal rate for copper remained above 85 percent throughout the trial (see Table 1). The goal of maintaining concentration levels of less than 12 μg/L was also achieved (Table 1). Additionally, the plant employed a pilot test with ion exchange resin. Although acceptable removal rates were obtained with this method, a pH adjustment was required to achieve low copper residuals. By using the metal removal media, the pH adjustment, ORP adjustment or other chemical pretreatment steps were not necessary. As a result of this increased regulation, multiple facilities will now need to begin treating their cooling tower blowdown. Many, especially small to mid-

sized manufacturers, do not currently have an existing waste treatment system in place. Therefore, a simple solution, that is not chemical treatment intensive or that creates a separate hazardous waste that will then need to be treated is available to treat these waste streams. In such cases, the use of metals removal media will be a simplified solution. The use of the media is not equipment intensive and can easily be ramped from low flowrates of five gallons per minute up to the high flowrates that are common at large utilities. PE

Boiler MACT Rules Remain UNCERTAIN By SARAH SAJEDI, LAURA WEINKAM and ALEX CHAMBERLAIN

A brief discussion on the recent history of the boiler MACT regulations and a look at more changes down the road.

F

ollowing a lawsuit from the Sierra Club, the EPA was originally directed by a court order tto finalize rules for new and existing sources of toxic air pollutants, specifically from boilers, by Dec. 16, 2010. After the proposed rule was publicized, the EPA received nearly 5,000 comments from industrial groups and fuel industry advocates who argued that the agency’s method of selecting the top 12 percent of existing sources was flawed and unfair. Several groups claimed that the boiler’s maximum achievable control technology (MACT) rules were developed based upon a hypothetical boiler model that did not actually exist, and that the costs of compliance would be extremely high and detrimental to all affected industries. Based on the feedback received from the public, the EPA requested a 15-month deadline extension in order to issue final Boiler MACT rules, but the request was denied by the U.S. District Court. On March 21, 2011 the EPA published national emission standards for hazardous air pollutants (NESHAP) for industrial, commercial, and 30

This legislation would extend compliance deadlines for new major sources for an additional three to five years.

to the publication of these rules, the agency also published a proposed notice of selected reconsiderations for both. The EPA cited a process outlined in the Clean Air Act as the basis for reconsideration of these rules to ensure additional opportunities for public comment and review. The EPA reopened the public comment period following its publication of the final rules in March. Despite industry group criticisms, the agency defended the methodology for the creation of the final

”

Despite publication of the final rules for major and area sources, the EPA has delayed the effective dates for major source boilers until the proceedings for judicial review of the rule are complete or until the agency completes its reconsideration of the rule. The EPA will publish an announcement in the Federal Register regarding the effective dates once delay is no longer necessary. The rule for area source boilers, however, is currently in effect, despite the notice of reconsideration published by the EPA.

NEW APPROACHES to

Emissions and Energy Management

By ALVIN HAYES, Communications Manager for IHS

Gathering data from multiple sources can be tedious and may lead to omissions and errors. This company’s innovative system minimized such missteps while also providing details only imagined in the past. s it began its independent operations in 2009, Cenovus Energy Efficiency, a Canadian oil company headquartered in Calgary, Alberta, was committed to establishing industry-leading, novel ideas and approaches. To this day, the company is still focused on applying fresh, progressive thinking to safely and responsibly unlock energy resources that the world needs. Its operations include oil sands projects in northern Alberta that use specialized methods to bring oil to the surface. At the same time, it also owns wellestablished oil and natural gas properties in southern Alberta and Saskatchewan, as well as interests in two major U.S. refineries. The company is currently demonstrating a commitment to innovation and responsibility while also addressing the interrelated challenges of environmental compliance, greenhouse gas (GHG) emissions and the improvement of energy effi-

“

process that involved the collection and aggregation of data from multiple sources across many facilities. Much of the data would require additional pre-calculation or other conditioning in order to be suitable for emissions calculation and compli-

If you don’t measure it, you can’t control it.

“Conventional upstream oil and gas production operations are characterized by many small emissions sources. Some of the emission sources are supplied by measured fuel streams, but many are not,” said Lee Wagner, coordinator for the energy company. Initially, the company created numerous spreadsheets and systems to compile emissions data and to produce reports. It was an onerous and labor-intensive

ance report compilation. The company envisioned a single, automated and integrated enterprise-wide solution to help manage air environmental reporting. “We wanted to transition to a selfcontained, all-inclusive internal reporting system that would be much more granular in terms of emissions data. We wanted an emissions reporting tool that provided a lot of detailed output with minimal effort on the data input task,” said Wagner.

NEW APPROACHES to Emissions and Energy Management

The system would use “more science and fewer estimates,” and receive physical operating data directly from existing platforms wherever possible. All necessary calculations, such as fuel apportionment between multiple consumers from a single metered source, would be totally accomplished within the system, and based on traceable operational measurement. Today, Wagner and his team are saving time by using their enterprise-wide opsInfo platform to aggregate data from the bottom up – including public databases, data from internal measurement systems and from production accounting systems – and automatically integrate all of that information into a single detailed emissions data set, with no additional calculations, conversions, or conditionings required outside of the application. Therefore, operators can enter operational measurements, while the system provides up-to-date air emissions statistics. “Now all of our data is in one place. We have production data and emissions data in one system. This gives us a more complete picture of air emissions and many aspects of facility operational efficiency,” said Wagner. “We have the detailed data for each individual emissions source within each facility – the emissions, fuel, vent, flare volumes, efficiency trends and more – derived from science, with less reliance on bulk estimates. It was important for us to have an accurate and standardized methodology for all facilities. The standardization and detail allows us to compare facility to facility emissions intensity and other efficiency measures regardless of facility type or size.” “Beyond just reporting, we wanted to build a total emissions management tool. So we went extremely granular on our input data. The software allows us to reasonably trace facility emissions to each individual piece of equipment,” said Wagner. “Knowing that a facility has a high volume of CO2 emissions is one thing, but knowing exactly how much is being emitted by each specific equipment type and processes is another. If you don’t measure it, you can’t control it.” The new emissions and energy management system supports a strong corporate

THE CHALLENGES • Obtain a detailed emissions reporting system across widely dispersed facilities. • Monitor company air emissions and identify potential improvement areas. • Streamline the data input and reporting process while also providing more detailed data. • Finally, the company aspired to improve its energy efficiency and to implement benchmark improvements across multiple facilities.

THE SOLUTION Environmental compliance, GHG and energy management, with the utilization of both data collection and reporting software, would need to be implemented.

THE RESULTS • The company established one integrated, automated emissions system across more than 1,000 facilities. • The system eliminated the old input spreadsheets and legacy systems. • The system now traces emissions to individual equipment sources. • The company can now incorporate energy-efficiency and facility operations efficiency metric reporting. • Such metric reporting saves the company time by automatically downloading data from internal measurement systems, which eliminates the need for manual data conditioning. • Company forecasting and what-if scenario generation facilitates future planning. • The company now has increased confidence in its emissions program through standardization, integration and transparency

culture of continuous improvement. Wagner said, “Our business planners are very interested in what we can provide because it’s much more data than we’ve ever had and it tracks emissions and processes at a much lower level. It allows them to do a much better job in forecasting their future.” Company staff can also develop what-if scenarios within the solution; forecasts that can help them determine the overall impact of production and facility growth, or forecasts that show the effect of facility optimization and energy-efficiency initiatives. Now staff members can ensure greater accountability and data integrity, because the software tracks all edits to the data. If data required change, the system has an automatic audit trail that shows when the change was made and who made it. By implementing its new information system,

the company was able to achieve a higher level of confidence in its own emissions and energy management capabilities. “From a process measurement of pressure or flow to an air emissions volume, every calculation from end to end is in one place and visible. That transparency has increased the comfort factor of the transition,” said Wagner. “It’s a quantum leap to be able to quickly go from a facility emissions overview to drill down to a very, very granular look at each emissions source. You can see the trends and you know where you’re going.” PE Alvin Hayes is the communications manager for product marketing, EHS and sustainability at IHS and is based in Engelwood, Colo.

Groundwater Remediation – Part 1 As groundwater remediation methods continue to increase, the choices may seem complex. So what is the most sensible option? o remove hazards or contaminants from groundwater, scientists and engineers have a number of choices. Remediation is typically required when concentrations of contaminants exceed, or are expected to exceed, predetermined levels set by either the EPA or by local environmental authorities, depending on the type of resource that is impacted. For example, lead levels in drinking water should never exceed the EPA action level of 0.015 mg/L. Remediation generally involves removing or containing contaminants within an area. A range of methods have been devised to treat various contaminants in many types of aquifers over the years. Eight of the more common remediation methods will be discussed. Also, it is important to realize that remediation methods depend on several factors, including: • Hydrogeologic setting • Contaminant characteristics • Physical properties • Chemical properties (solubility, sorption) • Subsurface access and land use • Toxicity risk • Cost Some of the most commonly used methods include: • Phytoremediation, which takes advantage of a plant’s natural affinity for specific chemical constituents. • Pump and treat, which involves the removal of contaminated water by strategically placed wells and treating the extracted water. • Air sparging and vapor extraction, which treat groundwater contaminated with VOCs. • In-situ flushing, which uses solvents or detergents to wash contamination to a collection system. • Permeable reactive barriers, which passively remove contamination as water naturally flows through the system. • Monitored natural attenuation, a technique in which nature actually destroys all of the contamination. • Intrinsic and enhanced bioremediation, which utilizes bacteria to break down carbon-based contamination. Since some groundwater remediation situations may require the utilization of more than one technique to solve the problem and to reach desired cleanup levels, I will describe each of these methods in upcoming columns so that the reader may be prepared to make a more educated decision.

T

At the same time, learning should never cease. By discussing each of these applications, additional conversations may be sparked with colleagues that possibly result in the development of innovative ideas for new methods. For now though, let’s start such a discussion by focusing on phytoremediation.

“

Remediation generally involves removing or containing contaminants within an area.

”

Quite often, EPA will use phytoremediation since it takes advantage of natural plant processes. It requires less equipment and labor than many other methods since plants perform most of the work. Such a process allows workers to avoid contact with harmful chemicals. Phytoremediation has been successfully tested in many locations, and is currently being employed at several Superfund sites. The time spent during the clean up process while using phytoremediation depends upon several factors, including: • The types and number of plants that are actually used. • The types and volumes of harmful chemicals present. • The size and depth of the polluted area. • The types of soil and conditions that are present. Remember, each of these factors tend to vary from site to site. Plants may have to be replaced if they are destroyed by animals or unpredictable weather conditions. If plants are destroyed, the cleanup process will, of course, be lengthened. Often, site clean up may occur for many years while using a process such as phytoremediation. PE

CA –TOPS IN GREEN JOBS

Los Angeles has recently surpassed the Bay Area as home to more green jobs than any other region in the nation. Such jobs will more than double in the next 30 years, according to a study by Californians for Clean Energy and Jobs (CCEJ) Network. The report is available at www.cabrightspot.com/images/stories/ GreenJobsintheLosAngelesRegionReport.pdf.

LA – DEQ JOINS TRI DATA EXCHANGE

As of late, the DEQ announced its membership in the Toxic Release Inventory (TRI) Data Exchange. The TRI exchange allows facilities to meet federal requirements regarding annual TRI reports that are presented to state agencies upon submitting all data to the federal agency itself.

NH – NEW GENERAL PERMIT FOR POTWS

The EPA recently released a notice of availability of the final NPDES General Permits for certain Publicly Owned Treatment Works Treatment Plants (POTW) and other treatment works for domestic sewage in New Hampshire and Massachusetts. The permit replaces the prior POTW GP that had been implemented in previous years.

OR – TITLE V PERMITS NOW ONLINE

One hundred and twenty sources are currently permitted under the state’s Title V Operating Permit Program; all permits can now be accessed online. The DEQ believes online permits will allow citizens to learn more about the companies that are operating in their neighborhoods – through a faster, more efficient process. The permits are available at www.deq.state.or.us/aq/permit/ alphalist.htm.

VA –RULES FOR ELECTRIC GENERATING FACILITIES

The state’s Air Pollution Control Board is currently required to develop a general permit for the construction, installation, and operation of distillate oil, natural gas, liquid propane gas, and biodiesel-fired electric generating facilities that participate in a voluntary demand response program (i.e., load curtailment, demand response, peak shaving or similar program). Such facilities must also qualify as “nonmajor” under the federal CAA. The new regulations, which became effective Aug. 17, 2011, are now addressing this requirement.

WI – CLEAN DIESEL GRANTS ARE GREAT!

According to a new report released by the DNR, the state is currently benefitting, and will substantially benefit more in the future, from the pollution reduction, health cost savings, and local economic incentives provided through clean diesel grants. The grant programs offer financial assistance to diesel equipment operators to purchase and install technologies that will reduce emissions from older diesel equipment, while also often improving their bottom lines.
