National Emission Standards for Hazardous Air Pollutants: Organic Liquids Distribution (Non-Gasoline) Residual Risk and Technology Review

Resumo

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Organic Liquids Distribution (Non-Gasoline) (OLD) source category. The EPA is proposing amendments to the storage tank and equipment leak requirements as a result of the residual risk and technology review (RTR). The EPA is also proposing amendments to allow terminals the option to implement a fenceline monitoring program in lieu of the enhancements to the storage tank and equipment leak requirements; correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM); add requirements for electronic reporting of performance test results and reports, performance evaluation reports, compliance reports, and Notification of Compliance Status (NOCS) reports; add operational requirements for flares; and make other minor technical improvements. We estimate that these proposed amendments would reduce emissions of hazardous air pollutants (HAP) from this source category by 386 tons per year (tpy), which represents an approximate 16-percent reduction of HAP emissions from the source categ
