## Abstract

This action finalizes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Off-Site Waste and Recovery Operations (OSWRO). The final amendments address continuous monitoring on pressure relief devices (PRDs) on containers. This issue was raised in a petition for reconsideration of the 2015 amendments to the OSWRO NESHAP, which were based on the residual risk and technology review (RTR). Among other things, the 2015 amendments established additional monitoring requirements for all PRDs, including PRDs on containers. For PRDs on containers, these monitoring requirements were in addition to the inspection and monitoring requirements for containers and their closure devices already required by the OSWRO NESHAP. This final action removes the additional monitoring requirements for PRDs on containers that resulted from the 2015 amendments because we have determined that they are not necessary. This action does not substantially change the level of environmental protection provided under the OSWRO NESHAP, but reduces burden to this industry compared to the current rule by $28 million in capital costs related to compliance, and $4.2 million per year in total annualized costs under a 7 percent interest rate. Over 15 years at a 7-percent discount rate, this constitutes an estimated reduction of $39 million in the present value, or $4.3 million per year in equivalent annualized cost savings.
