AECOM Process Technologies offers myriad products and services to ensure current and future environmental regulatory compliance. 

What follows are some common industry regulations impacting the different markets we serve. Click through to learn more about both the regulations and our solutions.


Clean Power Plan

The proposed Clean Power Plan is a first of its kind plan to address climate change by reducing carbon pollution from existing power plants. On average, the proposed plan will reduce carbon emissions from the power sector to 30% below 2005 levels by 2030. The plan requires each state that currently generates power from fossil fuels to achieve state-specific reductions ranging from as low as 11% to as high as 72%.

Coal Combustion Residuals Rule

The Disposal of Coal Combustion Residuals from Electric Utilities Rule regulates the safe disposal of coal combustion residuals (CCRs) generated from coal-fired power plants.  The Rule addresses risks from coal ash disposal through the establishment of specific requirements for CCR landfills and surface impoundments under Subtitle D of the Resource Conservation and Recovery Act (RCRA).

The Rule specifies design criteria for landfills and impoundments (including location restrictions), requires structural integrity assessments of existing and future facilities, and dictates requirements for their ultimate closure.  Furthermore, it stipulates strict monitoring and reporting requirements, which includes groundwater monitoring, emergency action plans, flood control plans, and post-closure care.

Cross-State Air Pollution Rule (CSAPR)

The Cross-State Air Pollution Rule (CSAPR) requires 28 states—predominantly in the eastern half of the United States—to reduce SO2 and NOx emissions to levels that will not impact downwind states’ abilities to comply with National Ambient Air Quality Standards (NAAQS) for ozone and fine particle pollution. The rule is an extension of the “good neighbor” provision of the Clean Air Act.

Industrial Boiler MACT

This rule applies to high-emitting boilers and incinerators, and sets emission limits for mercury, non-mercury metals, particulate matter, and acid gases. Major source and affected area source boilers have three years to comply and can be granted a fourth year if needed to install controls.

Mercury & Air Toxics Standard (MATS)

The Mercury and Air Toxics Standards (MATS) applies to coal- and oil-fired electric utility steam-generating units larger than 25 MW in capacity. It is the first national standard to reduce emissions of mercury and other toxic air pollutants (including acid gases, particulate matter, and metals).

National Ambient Air Quality Standards

The Clean Air Act (CAA) requires the US EPA to set primary and secondary National Ambient Air Quality Standards (NAAQS) for six “criteria” pollutants considered harmful to public health and the environment: carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter (PM), and sulfur dioxide.

Regional Haze

The Regional Haze Rule requires reductions in fine particulate that contribute to visibility impairment in national parks and wilderness areas. Man-made sources of fine particulate include power plants, industrial and manufacturing processes, and motor vehicles.

Steam Electric Power Generating Effluent Guidelines (ELGs)

The Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category (ELGs) were updated in September of 2015. The Rule continues to apply to power plants whose primary purpose is the sale of energy, with different requirements based on whether an electric generating units capacity is less than or greater than 50 MW.

The Rule’s focus is on FGD wastewater, landfill leachate, coal ash transport waters, gasification wastewater, and mercury control related wastewater. Pollutants of concern include selenium, arsenic, mercury, nitrates-nitrogen, and total dissolved solids.
