EPA Air Quality Standards and Regulatory Approach
National Ambient Air Quality Standards Process
Under Wehrum, the EPA revisited existing National Ambient Air Quality Standards for pollutants such as ozone and particulate matter. These reviews shaped how scientific advice was weighed against implementation costs and industry feedback.
Reconsideration of Obama-Era Rules
Wehrum directed efforts to replace or revise rules like the Clean Power Plan and methane emissions guidelines. The focus was on altering the cost-benefit assumptions and narrowing the scope of regulated sources.
Science Transparency and Data Use Policies
Strengthening Science Considerations
Efforts under Wehrum emphasized clearer documentation of how scientific studies support regulatory decisions, aiming to make technical assessments more accessible to reviewers and the public.
Data Transparency Initiatives
Proposals to require original raw data for certain studies generated debate over reproducibility, privacy, and the feasibility of using some datasets for public health assessments.
Stationary Source Regulation and Permitting
New Source Review Reform
Wehrum oversaw revisions to New Source Review that sought to streamline permitting, reduce duplication, and provide more predictability for companies updating existing facilities.
Coal-Fired Power Plant Standards
Adjustments to effluent guidelines and wastewater limits targeted the treatment of coal combustion residuals and related wastewater pollutants from power plants.
Climate, Energy, and Emissions Policy
Greenhouse Gas Endangerment Finding
While the finding that greenhouse gases endanger public health remained largely intact during this period, subsequent actions revisited how its implications were translated into specific regulations.
Fuel Economy and Emissions Standards
Wehrum was involved in discussions around motor vehicle rules, including efforts to adjust Corporate Average Fuel Economy standards and related greenhouse gas requirements.
