Iowa Code r. 567-24.300 - Operating permit by rule for small sources

Except as provided in 24.300(11), any source that otherwise would be required to obtain a Title V operating permit may instead register for an operation permit by rule for small sources. Sources that comply with the requirements contained in this rule will be deemed to have an operating permit by rule for small sources. Sources that comply with this rule will be considered to have federally enforceable limits so that their potential emissions are less than the major source thresholds for regulated air pollutants and hazardous air pollutants as defined in 567-24.100 (455B).

(1) Definitions for operating permit by rule for small sources. For the purposes of 567-24.300 (455B), the definitions shall be the same as the definitions found in 567-24.100 (455B).

(2) Registration for operating permit by rule for small sources.

a. Except as provided in 24.300(3) and 24.300(11), any person who owns or operates a stationary source and meets the following criteria may register for an operating permit by rule for small sources:

(1) The potential to emit air contaminants is equal to or in excess of the threshold for a major stationary source of regulated air pollutants or hazardous air pollutants, and

(2) For every 12-month rolling period, the actual emissions of the stationary source are less than or equal to the emission limitations specified in 24.300(6).

b. Eligibility for an operating permit by rule for small sources does not eliminate the source's responsibility to meet any and all applicable federal requirements including, but not limited to, a MACT standard.

c. Nothing in this rule shall prevent any stationary source that has had a Title V operating permit from qualifying to comply with this rule in the future in lieu of maintaining an application for a Title V operating permit or upon rescission of a Title V operating permit if the owner or operator demonstrates that the stationary source is in compliance with the emissions limitations in 24.300(6).

d. The department reserves the right to require proof that the expected emissions from the stationary source, in conjunction with all other emissions, will not prevent the attainment or maintenance of the ambient air quality standards specified in 567-Chapter 22.

(3) Exceptions to eligibility.

a. Any affected source subject to the provisions of Title IV of the Act or any solid waste incinerator unit required to obtain a Title V operating permit under Section 129(e) of the Act is not eligible for an operating permit by rule for small sources.

b. Sources that meet the registration criteria established in 24.300(2)"a" and meet all applicable requirements of 567-24.300 (455B), and are subject to a standard or other requirement under 567-subrule 23.1(2) (standards of performance for new stationary sources) or Section 111 of the Act are eligible for an operating permit by rule for small sources. These sources shall be required to obtain a Title V operating permit when the exemptions specified in 24.102(1) or 24.102(2) no longer apply.

c. Sources that meet the registration criteria established in 24.300(2)"a" and meet all applicable requirements of 567-24.300 (455B), and are subject to a standard or other requirement under 567-subrule 23.1(3) (emissions standards for hazardous air pollutants), 567-subrule 23.1(4) (emissions standards for hazardous air pollutants for source categories), or Section 112 of the Act are eligible for an operating permit by rule for small sources. These sources shall be required to obtain a Title V operating permit when the exemptions specified in 24.102(1) or 24.102(2) no longer apply.

(4) Stationary source with de minimus emissions. Stationary sources with de minimus emissions must submit the standard registration form and must meet and fulfill all registration and reporting requirements as found in 24.300(8). Only the recordkeeping and reporting provisions listed in 24.300(4)"b" shall apply to a stationary source with de minimus emissions or operations as specified in 24.300(4)"a":

a. De minimus emission and usage limits. For the purpose of this rule, a stationary source with de minimus emissions means:

(1) In every 12-month rolling 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 hazardous air pollutants (HAPs)), and

2. 2 tons per year of a single HAP, and

3. 5 tons per year of any combination of HAPs.

(2) In every 12-month rolling 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 numbered paragraphs "1" to "9" below:

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;

2. 750 gallons of any combination of solvent-containing materials where the materials contain the following: methyl chloroform (1,1,1-trichloroethane), methylene chloride (dichloromethane), tetrachloroethylene (perchloroethylene), or trichloroethylene, but not more than 300 gallons of any one solvent-containing material;

3. 365 gallons of solvent-containing material used at a paint spray unit(s);
