100 GENERAL
 

101 APPLICABILITY: This Rule shall apply to any stationary source which would, if it did not comply with the limitations set forth in this Rule, have the potential to emit air contaminants equal to or in excess of the threshold for a major source of regulated air pollutants or a major source of Hazardous Air Pollutants (HAPs) and which meets one of the following conditions:

101.1 In every 12-month period, the actual emissions of the stationary source are less than or equal to the emission limitations specified in Section 301; or

101.2 In every 12-month period, at least 90 percent of the emissions from the stationary source are associated with an operation limited by any one of the alternative operational limits specified in Section 601.


102 EXEMPTION RECORDKEEPING AND REPORTING FOR A STATIONARY SOURCE WITH DE MINIMIS EMISSIONS: The recordkeeping and reporting provisions in Sections 400, 500 and 600 shall not apply to a stationary source with de minimis emissions or operations as specified in either Section 102.1 or 102.2:

102.1 In every 12-month period, the stationary source emits less than or equal to the following quantities of emissions:

  1. 5 tons per year of a regulated air pollutant (excluding HAPs);
  2. 2 tons per year of a single HAP;
  3. 5 tons per year of any combination of HAPs; and
  4. 20 percent of any lesser threshold for a single HAP that the United States Environmental Protection Agency (U.S. EPA) may establish by rule.

102.2 In every 12-month period, at least 90 percent of the stationary source's emissions are associated with an operation for which the throughput is less than or equal to one of the quantities specified in subsections (a) through (i):

  1. 1,400 gallons of any combination of solvent-containing materials but no more than 550 gallons of any one solvent-containing material, provided that the materials do not contain the following: methyl chloroform (1,1,1 trichloroethane), methylene chloride (dichloromethane), tetrachloroethylene (perchloroethylene), or trichloroethylene;

1 Based on the SIP rules - District Rule 2.25 and Rule 2.26, which were adopted by the Board in 1994 and are awaiting EPA's approval. The rules allow the use of coatings that have volatile organic compounds (VOC) content of 3.5 Lbs./gallon. The projected emission cap is 5 tons/year.

103 PROVISION FOR AIR POLLUTION CONTROL EQUIPMENT: The owner or operator of a stationary source may take into account the operation of air pollution control equipment on the capacity of the source to emit an air contaminant if the equipment is required by Federal, State, or District Rules and Regulations or permit terms and conditions. The owner or operator of the stationary source shall maintain and operate such air pollution control equipment in a manner consistent with good air pollution control practice for minimizing emissions. This provision shall not apply after January 1, 1999, unless such operational limitation is federally-enforceable or unless the District Board specifically extends this provision and it is submitted to the U.S. EPA. Such extension shall be valid unless, and until, the U.S. EPA disapproves the extension of this provision.

104 EXEMPTION, STATIONARY SOURCE SUBJECT TO RULE 3.8, FEDERAL OPERATING PERMITS: This Rule shall not apply to the following stationary sources:

104.1 Any stationary source whose actual emissions, throughput, or operation, at any time after the effective date of this Rule, is greater than the quantities specified in Sections 301 or 601 and which meets both of the following conditions:

  1. The owner or operator has notified the District at least 30 days prior to any exceedance that he/she will submit an application for a Part 70 permit, or otherwise obtain federally-enforceable permit limits; and
  2. A complete Part 70 permit application is received by the District, or the permit action to otherwise obtain federally-enforceable limits is completed, within 12 months of the date of notification.

However, the stationary source may be immediately subject to applicable federal requirements, including but not limited to, a maximum achievable control technology (MACT) standard.

104.2 Any stationary source that has applied for a Part 70 permit in a timely manner and in conformance with Rule 3.8, FEDERAL OPERATING PERMITS, and is awaiting final action by the District and the U.S. EPA.

104.3 Any stationary source required to obtain an operating permit under Rule 3.8, FEDERAL OPERATING PERMITS, for any reason other than being a major source.

104.4 Any stationary source with a valid Part 70 permit. Notwithstanding Sections 104.2 and 104.4, nothing in this section shall prevent any stationary source which has had a Part 70 permit from qualifying to comply with this Rule in the future in lieu of maintaining an application for a Part 70 permit or upon rescission of a Part 70 permit if the owner or operator demonstrates that the stationary source is in compliance with the emissions limitations in Section 301 or an applicable alternative operational limit in Section 601.


105 EXEMPTION, STATIONARY SOURCE WITH A LIMITATION ON POTENTIAL TO EMIT: This Rule shall not apply to any stationary source which has a valid operating permit with federally-enforceable conditions or other federally-enforceable limits limiting its potential to emit to below the applicable threshold(s) for a major source as defined in Sections 206 and 207.

106 APPLICABLE PUBLIC INFORMATION REQUESTS: Within three years of the effective date of Rule 3.8, FEDERAL OPERATING PERMITS, the District shall maintain and make available to the public upon request, for each stationary source subject to this Rule, information identifying the provisions of this Rule applicable to the source.

107 PRE-CONSTRUCTION PERMIT APPLICABILITY: This Rule shall not relieve any stationary source from complying with requirements pertaining to any otherwise applicable preconstruction permit, or to replace a condition or term of any preconstruction permit, or any provision of a preconstruction permitting program.2 This does not preclude issuance of any preconstruction permit with conditions or terms necessary to ensure compliance with this Rule.
