NOTICE OF PROPOSED RULEMAKING
Amendments to Nuisance Odor Requirements
The Director of the Department of Energy and Environment (DOEE or Department), pursuant to the authority set forth in Sections 5 and 6 of the District of Columbia Air Pollution Control Act of 1984 (the “Act”), effective March 15, 1985 (D.C. Law 5-165; D.C. Official Code §§ 8-101.05 and 8-101.06 (2016 Repl. & 2019 Supp.)); Section 107(4) of the District Department of the Environment Establishment Act of 2005, effective February 15, 2006 (D.C. Law 16-51; D.C. Official Code § 8-151.07(4) (2016 Repl. and 2019 Supp.)); and Mayor’s Order 2006-61, dated June 14, 2006; hereby gives notice of intent to adopt the following amendments to 903 (Odorous and Other Nuisance Pollutants) of Chapter 9 (Air Quality – Motor Vehicular Pollutants, Lead, Odors, and Nuisance Pollutants) of Title 20 (Environment) of the District of Columbia Municipal Regulations (DCMR) in no less than thirty (30) days from the date of publication of this notice in the District of Columbia Register.
The Act authorizes the Department to “[a]dopt standards governing emission of nuisance air pollutants likely to injure public health or welfare or interfere with reasonable enjoyment of life and property.” D.C. Official Code § 8-101.05(b)(1)(F). Moreover, regulations adopted as part of the Act prohibit emitting odorous or other air pollutants likely to injure public health or interfere with the reasonable enjoyment of life or property. Act § 3 (20 DCMR § 903; 32 DCR 647). The proposed amendments will strengthen DOEE’s ability to enforce this nuisance-odor prohibition. Though DOEE receives regular citizen complaints regarding nuisance odors from various types of sources, the complaints have, at times, been difficult to investigate due to the potential for odors to dissipate by the time the inspector arrives at the scene. Consequently, the Department is proposing to adopt a requirement that stationary sources emitting odors adopt an Odor Control Plan (OCP) under certain circumstances. This gives DOEE the ability to enforce compliance with the OCP in addition to the nuisance odor prohibition. If a source continues to emit nuisance odors despite compliance with the plan, DOEE would have the authority to require the source to update the plan in order to abate the nuisance.
The proposed rulemaking would require an OCP in three (3) circumstances. First, an OCP is required when DOEE identifies a nuisance odor from a source that is detectable when one (1) volume of odorous air has been diluted with two (2) or more volumes of odor-free air. Second, an OCP is required when DOEE receives odor complaints about a source from three (3) or more separate households or businesses within a thirty (30) day period, and a DOEE investigation verifies the suspected source of the odor and the affected parties. The third circumstance is if the source falls into one of six (6) source categories that are the most frequent sources of odor complaints. These source categories are (1) cannabis production operations; (2) certain types of painting operations, including autobody paint booths; (3) trash transfer stations; (4) asphalt processing plants; (5) wastewater treatment facilities; and (6) commercial solid fuel-fired cooking operations.
DOEE hereby gives notice of the intent to adopt these rules as final in not less than thirty days after the publication of the notice in the District of Columbia Register. Instructions for submitting comments may be found at the end of this notice.
Chapter 9, Air Quality – MOTOR VEHICULAR POLLUTANTS, LEAD, ODORS, AND NUISANCE POLLUTANTS, of Title 20, Environment, of the DMCR is amended as follows:
Section 903, odorous or other nuisance air pollutants, is amended to read as follows:
903.1 An emission into the atmosphere of odorous or other air pollutants from any source in any quantity and of any characteristic and duration that is, or is likely to be, injurious to the public health or welfare, or that interferes with the reasonable enjoyment of life and property, is prohibited.
903.2 The Department may require an owner or operator of a stationary source of odorous air pollutants to submit an Odor Control Plan (OCP) to the Department if:
(a) The source emits odorous air pollutants that are detected by a trained inspector using a field olfactometer when one (1) volume of odorous air has been diluted with two (2) or more volumes of odor-free air, as measured at a location or locations where it is likely odorous air pollutants will be detected given the prevailing atmospheric conditions; or
(b) The Department receives three (3) or more complaints about the source from distinct addresses, which includes distinct units, apartments, or suites at a single street address, within a thirty (30) day period; provided, that:
(1) Each complainant signs and submits a written statement containing the following information:
(A) The complainant’s name, address, and business, if applicable;
