According to the California Air Resources Board (CARB), diesel particulate constitutes approximately 70% of the statewide health risk associated with air toxics. The GARB is implementing a diesel particulate Risk Reduction Plan (RRP). The RRP includes establishment of new emission standards for new diesel engines, retrofit programs for existing engines, programs that facilitate conversion to reduced-emission diesel equipment, and limitations on sulfur content in fuel, among others. CARB projected that the RRP would generate overall reductions of 75% in diesel PM by 2010 and by 85% in 2020 with additional reductions expected in the longer term. The CARB has also published an Air Quality and Land Use Handbook that addresses air toxics risk with siting recommendations for air-pollutant-sensitive land uses. The scope of the Handbook includes a range of major potential TAC sources including freeways, distribution centers, rail yards, ports, refineries, chrome plating facilities, certain dry cleaners and gas stations. Projects within 500 feet of freeways have the potential to be exposed to significant health risk from diesel particulate emissions and should be subject to health risk screening or modeling as appropriate. GARB studies have shown that diesel particulate risk is reduced by more than 70% at distances greater than 500 feet from freeways, and projects at this or greater distances are not considered acutely threatened by freeway-related emissions. The Sacramento Metropolitan Air Quality Management District has defined such a screening process, which is applied in the impact analysis below (SMAQMD, 2009). Until recently, the project site has not been known to generate substantial odors. The existing Lincoln Road facility was the subject of a complaint filed with SJVAPCD in September 2005. The complainant alleged excessive dust emissions along with strong odors. An investigation by SJVAPCD did not confirm the complaint, as only mild odors were detected and no visible emissions were observed (SJVAPCD, 2005). No other complaints concerning the Lincoln Road facility are on record. An odor complaint against the existing Weber Street facility was received by the Stockton Code Enforcement Officer during the preparation of this Initial Study and forwarded to jCalRecycle. The complainant stated that a strong, bad odor came from the facility for one week, but was not so bad the following week. The complainant and other nearby residents had approached the City Council years ago about the Weber Avenue operation. In response, the City Council ordered the installation of tarp covers around the facility and to use deodorizing substances and misters to combat odors from the operation, this has been implemented at the project site. This is the only known complaint on record against this facility. As previously noted, the SJVAPCD has jurisdiction over most air quality matters in the SJVAB and implements the federal and California Clean Air Acts through local regulations. The SJVAPCD regulations that would be applicable to the project are summarized below.
