K%deptlagenda\Boartl Agendas\2D07 Board Agendast091907 workshop agenda.doc Orange County Sanitation District \WWI Setting Level of Service for Air Quality September 19, 2007 Policy Issue: OCSD expects the South Coast Air Quality Management District (SCAQMD)to amend existing regulations to require significant reductions in common pollutants (smog, visibility impairment) in December 2007. A secondary public health benefit of this regulation is the reduction in air toxic emissions. The estimated capital improvement cost to meet the new requirements is $29 million. 1. If the new regulations are not approved then OCSD will be required by 2012, under the existing regulations,to notify all affected residents and business surrounding our facilities of health risks associated with our emissions. 2. OCSD can avoid issuing notifications by proactively installing air pollution control equipment to reduce the air toxic emissions below the notification level. 3. In addition, approximately$2 million will be required to install air pollution controls to lower the risk to employees below the notification level. The SCAQMD does not require notification for employees. Analysis: Currently, state law and the SCAQMD require facilities to inventory their air toxic emissions and conduct a Health Risk Assessment of the health risk impact of their emissions to surrounding residents and businesses. Public notification is required if the cancer risk exceeds ten in one million and non- cancer risk exceeds one. This means that ten out of one million residents exposed to OCSD air emissions, over a 70-year period, can contract cancer. It is anticipated that after completion of full secondary facilities in 2012, OCSD will exceed the threshold established by SCAQMD and OCSD will be required to notify affected communities. New regulations proposed by the SCAQMD would require OCSD to make significant reductions in common pollutants. The most technically feasible and lowest cost solution will be to add air pollution controls to the existing engines, which would provide the added benefit of reducing air toxic emissions below levels that require public notification. However, additional controls would still be necessary to reduce risk to OCSD employees below the level of public notification. `v� Alternatives: (lithe new regulations are not enacted) t. Notify the affected public of the potential health risk from OCSD's toxic air emissions. OCSD would notify the public via direct mailings to the residents, businesses, and schools followed by public meetings. The corresponding materials will also be listed on the SCAQMD web site and, possibly, printed in local newspapers. 2. Add air pollution controls to reduce risk to community below public notification level. - and - Option A Install additional air pollution controls to lower the risk to employees below the notification level. - or- Option B Do not install additional air pollution controls to lower the risk to employees below the notification levels. Note: if the SCAQMD rule amendments are approved, the Board will still need to decide whether to expend the $2 million to lower the heakh risks of the employees. Staff Recommendation: OCSD should apply feasible and cost-effective controls in order to reduce the air toxic emissions below the health risk notification level to the surrounding community and OCSD employees. exx� Answers� to questions about... Central Power Generation System • Background 1 The Orange County Sanitation District(OCSD)is a public agency that provides wastewater collection, treatment and disposal services for approximately 2.5 million people in central and northwest Orange County.We operate two facilities- Reclamation Plant No. 1 in Fountain Valley and Treatment Plant No. 2 in Huntington Beach-and treat an average of 240 million gallons of wastewater each day. The energy cost to run our treatment plants is a significant part of our annual operations and maintenance budget. As such,we continuously strive to improve the efficiency and cost-effectiveness of our operations, while ensuring compliance with strict environmental regulations as well as conservation of natural resources. Consistent with these efforts,we have for more than 30 years used digester gas, also called biogas, a natural by-product of the treatment process, as a fuel at our plants to save energy. The Central Power Generation System helps us achieve our productivity and energy conservation goals by using all of the biogas we create. It allows us the option to r;.:r operate independent from the electric company while increasing operational reliability. And, because we have been able to substantially reduce energy costs, we are able to save millions of dollars each year and pass those savings on to our ratepayers, e a How Does the Central Power Generation System Work? Eight state-of-the-art, clean burning, internal combustion engines drive generators that produce electricity to run our two treatment plants. The three engines at Plant No. 1 Orange County and the five engines at Plant No. 2 were designed to minimize the emissions from Sanitation District engine exhaust and are fueled by natural gas and digester gas. Currently the District is reevaluating the engines to meet more stringent air quality regulations. Vision- To maintain world-class Digester gas is produced during the treatment process by the anaerobic (not requiring leadership in wastewater oxygen) bacteria in the digesters. The bacteria convert about 50 percent of the solids and water resource to digester gas. This biogas is approximately 65 percent methane and 35 percent management carbon dioxide and is an excellent fuel. • What Are the Benefits of the Central Power Generation System? We are able to improve plant reliability, and save ratepayers money by producing our own electricity. In the 1990's, Central Power Generation replaced 23 old internal combustion engines with eight new, state-of-the-art engines. These new engines greatly reduce emissions of oxides of nitrogen and carbon monoxide because digester gas has a low heat value, approximately one-half that of natural gas, burns slower and thus produces less of these air emissions; however in the future these engines may require modifications to meet more stringent air quality requirements. Fount Ellis Avenue o How Does This Project Improve Reliability? Fountain Valley, CA I P tY 92708-7018 The Central Power Generation System, along with the Southern California Edison grid, are two sources of power. Our major plant processes require continuous, reliable, for more information uninterrupted operations. One engine at Plant No. 1 and two at Plant No.2 are on call (714) 962-2411 standby, providing even greater reliability. The water pumping system and critical unit or visit our web site processes have a third source of electricity from emergency generators. v .ocsd .-continued on otherside j_jOCSD/091aW/C.nemudr P.Y.r • How Much Did the Central Power Generation System Project Cost and How Will It Be Paid For? _s This project cost was approximately$75 million to plan, design and construct, ,« and was financed through borrowing. It is estimated that it will pay for itself in less than 20 years through deferred electrical casts. • How Does Central Power Generation System Help the Organic solids are processed Current Energy Crisis? in digesters.each with an average 9y holding capacity of 2 million gallons The District cannot reduce power to the plant without affecting the treatment quality. This has become even more difficult as the District approaches secondary treatment goals and begins to supply high quality effluent to the _ Ground Water Replenishment System project. Fortunately, the Central Generation facilities at each plant provide a significant amount of the power required for operations. Newer air quality limitations have restricted use of the generators but they are ramped up to the maximum allowed during the hot summer days, both to save on energy costs and to support the _ State's utility grid. At Plant 2, we are able to supply the entire plant load and eliminate any imports of power, significantly helping conserve power and making Headworks mom sewdye pumpsr more available for community needs year round. The District continues to design a critical water pumping system energy efficiency into all new and rehabilitation projects, which help to reduce the for Plant No. I impact to the statewide power limitations. • How Much Does It Cost to Operate the Central Power onGeneration System? For the fiscal year July 2006 through June 2007, the combined costs for the Central Power Generation Systems at both treatment plants were as follows: �` Fuel Costs $ 1,279,555 Operating and Maintenance Costs 3,676,213 Iota/Costs $4,955.768 Electricity is used to operate ocean outfall booster station Income from Sales of Excess Power $ 44,152 motors at Plant No.2 Net Costs $4,911,616 The treatment plants produced an average of 11 MW during the year, or enough to power about 11,000 homes. Because we only pay for the natural gas and not the digester gas, our cost to produce power is only 4.7 cents per kWh.

Under current operating procedures, OCSD's goal is to contain odor nuisances within our property boundary. Currently, OCSD bases the level of odor subjectively with complaints received. This is not an accurate accounting of actual odors since most businesses, residents, and commuters do not call to complain and a resident may call and complain about a persistent odor over several days or weeks and this is counted as one complaint. To gauge odor nuisances accurately, OCSD Is changing to a scientifically based level of odor detection to determine accurately the Level of Service (LOS) it wishes to achieve for communities surrounding our treatment plants. The Board must then choose the desired LOS. Analysis: In 2002, OCSD completed the Odor Control Master Plan, which provided speck recommendations and measures to control and reduce odors. Staff conducted an extensive evaluation of OCSD facilities by collecting and analyzing odor samples from the plant processing equipment. The District used a panel of 6-8 people, with average olfactory sensitivity, to determine the odor detection thresholds scientifically based on the number of times the sample needed to be diluted before the panelist detected odor. Staff then assigned an odor unit to the sample -the higher the number of dilutions needed to achieve the threshold, the stronger the odor. Staff then fed the data into a computer model to predict the impact to the community. With the modeling analyses completed, staff concluded that under normal operation conditions, by using a guideline of 10 D/T (dilutions to threshold) OCSD would eliminate odor to the surrounding community. OCSD currently meets a 40-50 D/r,which is 4 to 5 times greater than 10 D/r. After the currently approved CIP projects are constructed, OCSD is estimated to reach a level of 25-30 DR (2.5 to 3 times greater than 10 D/r). Alternatives: 1. Adopt a treatment plant LOS of 25-30 dilutions/threshold. LOS will be achieved when the projects approved in the current CIP are constructed. Design and construct all future projects to a service level that will keep odors from that project on District property. Staff believes this level is 10 Drr but rase-by-case modeling for the projects will be required. The result is no cost Impact to the current approved CIP. 2. Adopt a treatment plant and future project design and construction LOS for odor control of 10 dilutions/threshold (within the fence line of OCSD) and incorporate into the CIP beginning in FY 2008-2009 implemented over an 11 year period to reduce the impact on rates. The result is an increase of$69.6 million to the CIP and $648.000 for O&M. Staff Recommendation: Staff is proposing that all new processes, structures and equipment at the wastewater treatment plants be designed so that the effect of odors from these new facilities, when combined with existing facilities, are contained within the facility property line. Staff proposes that the Board of Directors approve Alternative 2 and phase odor reduction capital improvements over 11 years to minimize financial impacts to ratepayers. o,HEE EEXI r4j Answers to questions about... Odor Control Program Who is the Orange County Sanitation District? The Orange County Sanitation District (OCSD) is responsible for safely collecting,treating, and disposing of wastewater generated by more than 2.5 million people living and working in Orange County. OCSD operates the third largest wastewater system on the West Coast, consisting of over 580 miles of sewers and two regional wastewater treatment plants in Fountain Valley and Huntington Beach. �. What causes odor from a wastewater treatment plant? Wastewater creates odor nuisances from a variety of sources, such as odors escaping from sewer maintenance holes and wastewater treatment facilities. The major cause of odors is sulfide compounds. When oxygen is not present in the trunk sewers, hydrogen sulfide can form. Hydrogen sulfide, easily detected in low concentrations, is quickly recognizable by its characteristic _ rotten egg smell. Its creation in wastewater systems occurs primarily in the slime layer that accumulates on pipe walls,in the sludge blankets of clarifiers, and other solids processing - units. At high concentrations hydrogen sulfide can be damaging to pipes and wastewater treatment facilities. Controlling Odors Currently,we remove odors by focusing on the treatment of hydrogen sulfide, but with the identification of odorous sulfur-and nitrogen-based compounds later in our process,we are beginning to focus on a comprehensive odor measurement program that will allow us to more effectively treat all types of odors emanating from our plants. OCSD controls odor in the collections system and the two treatment plants through three i/ methods: gas flaps, chemical dosing, and air scrubbers. - Gas Flaps— Placed inside a pipe or other structure, a gas flap is a piece of rubber,which >- allows the sewer water to flow through the pipe, but restricts air movement that causes ;;C �,"�i c• odors to escape. Chemical Dosing— In an effort to reduce odors throughout our service area and extend the useful life of OCSD's trunk line assets, chemicals are added to key trunk lines. Currently,four Orange trunk lines receive continuous treatment and eight trunk lines receive intermittent treatment Sanitation County Districtusing caustic soda dosing. Seven dosing stations in central and northern Orange County provide a continuous chemical feed to control odors. Additionally, as the wastewater enters the plant, the District adds odor control chemicals to react with sulfides to assist with odor control. Six trunklines at Plant No. 1, five trunklines leadership in uxatmater at Plant No. 2, and various sites throughout the treatment plants also receive chemical andwwramme treatment to control odor. mawgewni Air Scrubbers—While chemical dosing reduces odors, it does not eliminate it.As a result, OCSD covers most of the plant processes so odors cannot escape into the surrounding community.The covered processes include the screening areas,the grit chambers, rag and grit collection bins, flow splitter boxes, primary settling basins, dissolved air flotation thickeners, dewatering facilities, and solids storage areas. The air captured from the covered structures is forced into two-story tall towers called air scrubbers. OCSD currently uses two types of air scrubbers: chemical and biological. A carbon scrubber will be added in the near future,giving us a third type at our facilities. Chemical air scrubbers use chemicals to strip hydrogen sulfide and other odorous gases 10844 Ellis Avenue from the air.The odorous compounds from the foul air is adsorbed into the scrubber liquid Fountain Valley, CA and the clean air is released though the top of the tower. 92708-7018 The biological scrubbers utilize a biological process, meaning there are no chemicals used for _ information to strip the gases from the air. The air scrubber media contains small foam cubes where microorganisms attach to the foam media and consume the undesirable gases. or visit our web site ...continued on other side OCSa/091709/0d.,N, Pagel rOCSD also operates biofilters, another type of biological air scrubbers that contain rock-type media. Biofilters require much less liquid solution than the scrubbers; however, a larger f space is necessary for the same level of treatment. Plant 1 operates 12 tower chemical scrubbers, 1 biological scrubber, and 1 biofilter for odor control. Plant 2 operates 12 tower chemical scrubbers, 4 biological scrubbers and 1 biofilter i, for odor control. Characterizing Odor Since all people perceive odor differently, a chemical Lob staff collecting analysis does not necessarily provide information on how odorous a certain process is. a nao-undmismanalne In order to better understand and eliminate odors from our processes. OCSD periodically collects samples for analysis by an eight-person odor panel.The panel member uses an olfactometer, a device that takes a small portion of the odorous sample and delivers it in different ratios through a nosepiece, to a panel member who sniffs it. Based on the results, OCSD can understand the strength of the odor. Odor Complaint Process OCSD takes odor complaints very seriously and has a crew available 24 hours a day to respond to complaints. When the control center receives a complaint regarding the odor, the clerk will ask the caller for information to help OCSD identify the odor source. If the odor is currently occurring, OCSD will investigate the odor by going to the reported area of the odors, check the wind direction, and potential sources Air strabbers of odor in the area. Once staff determines the source of the odor, they will make changes to address the source of the odor. Staff completes a report to document the complaint and any actions taken. If the problem is not immediately obvious, further investigation may be necessary, such as smoke testing and monitoring of odors in the area. More Information OCSD is working on several capital projects to add additional odor control systems or to replace existing ones, which will provide a better means of controlling odors. However, if you encounter smells, even if you are not certain the odor is coming from the sewers or one of the OCSD plants, please contact us immediately at the Odor Complaints Hotline (714) 593-7025.
