Air Quality State Implementation Plans; Approvals and Promulgations: California; 1997 Annual Fine Particulate Matter Serious and Clean Air Act Section 189(d) Nonattainment Area Requirements; San Joaquin Valley, CA
The Environmental Protection Agency (EPA) is proposing to approve portions of state implementation plan (SIP) revisions submitted by the State of California to meet Clean Air Act (CAA or ``Act'') requirements for the 1997 annual fine particulate matter (PM2.5) national ambient air quality standards (NAAQS or ``standards'') in the San Joaquin Valley PM2.5 nonattainment area. Specifically, the EPA is proposing to approve those portions of the submitted SIP revisions as they pertain to the Serious nonattainment area and CAA section 189(d) requirements for the 1997 annual PM2.5 NAAQS, except for the requirement for contingency measures. In addition, the EPA is proposing to approve 2020 and 2023 motor vehicle emissions budgets and the trading mechanism for use in transportation conformity analyses for the 1997 annual PM2.5 NAAQS. The EPA will accept comments on this proposed rule during a 30-day public comment period.
Addition of Diisononyl Phthalate Category; Community Right-to-Know Toxic Chemical Release Reporting
The Environmental Protection Agency (EPA) is adding a diisononyl phthalate (DINP) category to the list of toxic chemicals subject to the reporting requirements under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA). In this action, EPA is adding the DINP category to the toxic chemical list as a category defined to include branched alkyl di-esters of 1,2 benzenedicarboxylic acid in which alkyl ester moieties contain a total of nine carbons. The DINP category meets the EPCRA chronic human health effects toxicity criterion because the members of the category can reasonably be anticipated to cause serious or irreversible reproductive dysfunctions as well as other serious or irreversible chronic health effects in humans, specifically, developmental, kidney, and liver toxicity.
