Washington D.C. Dept. of Energy and Environment finalizes revised source category permits for emergency engines subject to RICE MACT.

November 1, 2020

The Washington D.C. Department of Energy and the Environment (DOEE) finalized on September 30, 2020 revisions to two source category permits to construct and/or operate emergency engines within the District according to an October 12, 2020 Trinity Consultants report.

Specifically, these revised source category permits are for engines that are exempt from federal New Source Performance Standard (NSPS) Subpart JJJJ or Subpart IIII but are subject to National Emissions Standards for Hazardous Air Pollutants (NESHAP) Subpart ZZZZ (commonly referred to as the “RICE MACT”) (Source Category Permit Nos. 7115-SC-R1 and 7116-SC-R1).

Two notable changes are in the revised permits. They include revisions related to the visible emissions limit and types of acceptable recordkeeping for maintenance records. DOEE received one set of comments during the comment period which resulted in two minor changes to each of the permits.

Engines currently operating under the original source category permits must submit a renewal application by June 27, 2021. The renewal application may be submitted at any time prior to that date with no change in the expiration date of the renewed permit. The fee for an emergency engine will be either $500 or $1,000 depending on the engine size. At this time, DOEE is issuing invoices once an application is submitted; the 45-day approval clock for a source category permit does not begin until payment is received.

The application forms and permits can be found below:
