BOARD MEETING DATE: June 11, 1999 AGENDA NO. 5

CARB and the AQMD have mutually agreed to a list of projects related to FY 93-94 AB2588 funds. This action is to release RFPs for improved developing emission factors for cadmium from metal plating ($40,000); developing a more comprehensive emission inventory, risk assessment, and risk reduction guideline for motion picture film laboratories ($75,000); and developing enhanced emission inventories for rubber ($50,000); welding processes ($50,000); and furniture stripping and other small uses of methylene chloride ($100,000). These five RFPs represent some of the projects that AQMD and CARB have agreed to that will improve information on many AB2588 sources, which will benefit industry and agencies throughout the state. Other projects include development of: cumulative risk methodology and mapping, risk assessment tracking database, and bridging Title III with AB2588. Some of these will have RFPs in the future.

The Air Toxics "Hot Spots" Information and Assessment Act of 1987 (AB2588) requires certain facilities to submit comprehensive air toxics emission inventories to local air pollution control districts. AB2588 requires districts to use the data in these inventories to evaluate if a Health Risk Assessment (HRA) should be prepared to characterize the risk their toxic emissions pose to the surrounding community. This information also assists the AQMD in assessing the risks of toxic air contaminants for specific industries.

Staff proposes to release five RFPs and competitively select qualified contractors to conduct source tests and develop improved emission inventories for specific toxic air contaminants and specific industries within the South Coast Air Basin (Basin). The information and data collected through these projects will help companies comply with AQMD air toxics programs, such as the California Air Toxic "Hot Spot" program and AQMD Rule 1401 - New Source Review for Toxic Air Contaminants. The proposed RFPs entail the following projects:

Source Test and Develop Improved Emission Factors for Cadmium From Metal Finishing Processes:

The purpose of this RFP is to perform source testing of cadmium emissions from metal finishing operations and develop better cadmium emission factors for these processes.

Cadmium is classified as a Hazardous Air Pollutant (HAP) by EPA and a Toxic Air Contaminant (TAC) by the State of California. It affects the kidney and respiratory system. Cadmium’s main use is in electroplating or galvanizing because of its non-corrosive properties. Source tests are needed to refine existing and develop new cadmium emission factors from metal finishing operations.

Development of Refined Emission Inventory and Risk Reduction Guidelines for Motion Picture Film Processing:

The purpose of this RFP is to develop a more comprehensive emission inventory and risk reduction guidelines for better characterization and risk reduction from the motion picture film processing industry.

The motion picture film processing industry is primarily located in and around the Hollywood and Burbank areas of the Basin. This industry includes large, medium, and small processing labs. Based on industry information and health risk assessments, larger motion picture film processing labs may each create cancer risks to the surrounding community in the range of 5 to 70 in one million. Percholorethylene is the chemical causing most of the risk. Percholorethylene is classified as a HAP by EPA and a TAC by the state of California. It affects kidney, liver, and gastrointestinal system. Although some film printing equipment have permits, primarily because they are vented to permitted control devices, they were until recently exempt from permit requirements under Rule 219 – Equipment Not Requiring a Permit Pursuant to Regulation II. Therefore, the number of film printing equipment in the Basin is not precisely known, and an improved emission inventory from this source category is needed. This effort will also evaluate risk reduction methodologies. Smaller film processing labs may benefit from the risk assessment guidelines that may identify strategies such as alternative chemicals or processes, or control options.

Development of Improved Emission Inventory for Rubber Product Makers and Processors:

The purpose of this RFP is to develop a more refined emission inventory of criteria and toxic emissions for rubber product makers and processors. Two criteria pollutants, volatile organic compounds (VOC) and PM2.5, are included since many of the toxic air contaminants are also VOCs or particulate matter.

Many of the 188 HAPs in Title III of the Clean Air Act Amendments of 1990 are used in the manufacturing of rubber. In 1997, the AQMD identified approximately 225 facilities in the Basin with Standard Industrial Classification codes related to rubber manufacturing. Because many of these facilities have equipment exempt from permit requirements under AQMD Rule 219, emissions are not specifically identified or quantified. An improved emission inventory is needed to identify rubber manufacturing facilities in the Basin and their associated criteria and toxic pollutants.

Development of Emission Inventory for Metal Welding, Cutting and Spraying Operations:

The purpose of this RFP is to prepare better emission inventories for specific toxic metals (chromium, nickel, lead, zinc and cadmium) from metal welding, cutting and spraying operations. The contractor will be responsible for gathering emission factors, surveying applicable facilities and compiling emissions data.

Metal welding, cutting and spraying operations generate particles and fumes which contain toxic metals such as hexavalent chromium, nickel, lead, cadmium and zinc. The amount of toxic emissions from these sources, however, is not well documented. Thus, an emissions inventory is needed from metal welding, cutting and spraying operations.

Development of Improved Emissions Inventory for Furniture Stripping, and Other Small Uses of Methylene Chloride:

The purpose of this RFP is to develop a better emissions inventory for furniture stripping and other small uses of methylene chloride. The contractor will be responsible for gathering emission factors, surveying applicable facilities and compiling emissions data. A more detailed population database will be developed.

Methylene chloride is classified as a HAP by EPA and a TAC by the state of California. It affects the central or peripheral nervous systems, gastrointestinal system and liver. Methylene chloride is used in many applications. The largest use of methylene chloride is as the principal active ingredient in organic-based paint strippers in the furniture stripping industry. It is used in both consumer and industrial paint removers, where it is commonly present in 60%-80% concentration. Other applications of methylene chloride may include, but are not limited to, chemical processing, foam blowing, metal cleaning and finishing, aerosols, adhesive and coating, and electronics. Since methylene chloride has such a diversified usage, an improved emission inventory is needed to identify the major sources of methylene chloride emissions in the Basin.

Selection Process – Upon the Board’s approval, AQMD staff will distribute the attached RFPs and evaluate the proposals received. The evaluation will be based on Board-approved guidelines and include technical merit, contractor(s) qualifications, previous experience, and cost-and time-effectiveness.

In accordance with the AQMD’s consulting and contracting policies, a public notice advertising the RFP and inviting bids will be published in the following publications:
