Approval and Promulgation of State Plans for Designated Facilities; Commonwealth of Puerto Rico

概要

The Environmental Protection Agency (EPA) is proposing to approve the State plan submitted by the Commonwealth of Puerto Rico to implement and enforce the Emission Guidelines (EG) for existing sewage sludge incineration (SSI) units. Puerto Rico's plan is consistent with the EG promulgated by the EPA on March 21, 2011. Puerto Rico's plan establishes emission limits and other requirements for the purpose of reducing toxic air emissions and other air pollutants from existing SSI units throughout the Commonwealth. At the request of Puerto Rico, the EPA is proposing not to take action on a provision of its SSI plan allowing for affirmative defenses of Clean Air Act violations in the case of malfunctions. Puerto Rico submitted its plan to fulfill the requirements of sections 111(d) and 129 of the Clean Air Act.
