Handbook for Estimating the Potential Air Quality Impacts Associated with Oil and Gas Development Offshore California

摘要

This report consists of a workbook to estimate onshore air quality impacts associated with the exploration, development, and production of oil and gas resources offshore California. The handbook consists of two sections. The first section presents emission rates for various offshore activities. Pollutants analyzed include nitrogen oxides, sulfur dioxide, carbon monoxide, total suspended particulates, and volatile organic compounds. The emissions are presented in a format that allows rapid determination of emissions for various development scenarios and a large range of oil and gas production rates. The second section consists of results of inert and reactive air quality modeling for eight California coastal air basins. Calculated concentrations of inert pollutants are given for unit emission rates for various offshore distances. Ozone concentrations are estimated by various trajectory analyses for a range of oil and gas production rates and two transportation scenarios (tanker and pipeline). This section also presents a sensitivity analysis for the air quality models used.
