Background:

Cement and concrete are critical and irreplaceable building materials for our national economy, providing sustainable, resilient, safe, and energy-efficient building solutions for the development and maintenance of our nation’s infrastructure and built environment. When considered across their full life cycle, concrete and cement provide comparable if not superior performance in terms of embodied carbon, resilience, safety, environmental performance, and climate adaptability when compared against other building materials.

The cement industry is one of the most heavily regulated industries in the United States. Cement manufacturers comply with stringent requirements under environmental, health, and safety laws and regulations, and have invested billions of dollars in minimizing emissions and waste, reducing energy consumption, and using lower-carbon raw materials and alternative fuels.

Portland Cement National Emissions Standards for Air Pollutants (NESHAP)

Cement kilns must comply with strict emissions limits and testing, monitoring and reporting requirements for hazardous air pollutants. Building off an extensive record of risk and technology data provided by PCA and its members, In July 2018, EPA finalized the favorable Portland Cement NESHAP Residual Risk and Technology Review (RTR), declining to impose any new emissions control requirements on cement kilns and incorporating several technical amendments requested by PCA. Environmental groups have sought reconsideration of the rule and EPA granted reconsideration on the technical amendment revising the testing timeline for idled kilns. Environmental groups have also filed a petition for review with the D.C. Circuit Court of Appeals. EPA has also finalized guidance in April 2020 on the implementation of the Portland Cement NESHAP.

Coal Combustion Residuals

Cement kilns are uniquely designed to use coal combustion residuals as low-carbon feedstocks for manufacturing, and EPA has recognized the significant environmental and economic benefits of these uses. In August 2019, EPA issued a notice of proposed rulemaking (NPRM) to remove the 12,400-ton beneficial use threshold and impose additional storage restrictions on small inventories of CCRs temporarily stored for use in cement manufacturing. This rule was proposed despite the lack of any quantified benefit for the additional restrictions and the significant adverse environmental and economic implications should any change move forward. EPA did not finalize the proposed rule and has been working with stakeholders to gather information and reconsider further regulation of CCR piles. On December 22, 2020, EPA issued a Notice of Data Availability seeking public comment on whether the additional information collected from the NPRM and subsequent discussions with stakeholders may inform the Agency's reconsideration of the regulations concerning management of CCRs.

Alternative Fuels

The cement industry has a long history of safe and efficient use of alternative fuels, ranging from used tires and biomass to a wide variety of secondary and waste materials. An alternative fuel policy provides many benefits to our economy, environment, public health, and energy security. Secondary materials like post-industrial, post-commercial, post-consumer paper, plastic, and other materials have tremendous energy value. Their use as fuels helps to reduce industrial emissions of greenhouse gases (GHG) and other emissions, limit landfill disposal of materials that can become public health vectors and safety risks, conserve natural resources, and provide low-cost, sustainable fuels.

The cement industry is constrained by legal barriers through RCRA, the CAA, and the EPA regulating the use of non-hazardous secondary materials and wastes as fuels. These legal barriers prevent significant amounts of landfilled materials such as plastics, paper, fabrics/fibers, and other secondary materials from being used as fuels, despite their demonstrably lower greenhouse gas and other air emissions. Today, alternative fuels make up only about 13.5 percent of the fuel used by domestic manufacturers, compared to more than 36 percent in the European Union, including as high as 60 percent in Germany.

PCA seeks federal rules and guidance to remove unnecessary processing requirements and administrative requirements for exempting valuable, non-hazardous secondary materials from treatment as wastes to enable these valuable materials to be used as fuels.

New Source Review

The Clean Air Act places regulatory barriers on facilities from implementing energy efficiency, emissions reductions, and other technology upgrades due to the New Source Review (NSR) Program. The NSR Program was intended to ensure that “modifications” to facilities did not “significantly increase” emissions. In practice, the well-intentioned law has resulted in inconsistent application of the program by EPA, delayed maintenance, investment, and process improvements by manufacturers, and an unduly lengthy and burdensome permitting process. PCA is advocating to reform the NSR program and reduce barriers to making greenhouse reduction and other energy efficiency improvements at cement facilities without undergoing overly burdensome permitting processes.

National Ambient Air Quality Standards (NAAQS)

The cement industry implements the best available emissions control technologies and limits its emissions to ensure states meet established NAAQS. These standards are important to cement facilities because they help determine the permitting, emission control, and transportation restrictions imposed on businesses within non-complying areas and ensure regulatory certainty.

On December 21, EPA finalized the retention of the particulate matter (PM) NAAQS, aligned with the recommendation of the Clean Air Scientific Advisory Committee, that the current standards were sufficiently protective of human health and welfare. EPA program staff had recommended in their Policy Assessment that the standard be lowered. PCA supported retaining the PM NAAQS.

On December 31, EPA finalized the retention of the Ozone NAAQS, also aligned with the recommendation of CASAC and EPA program staff, that the current standards were sufficiently protective of public health. PCA supported retaining the Ozone NAAQS.
