Not

Attached Attached N/A

RULE EVALUATION FORM: See instructions for completing the Rule 

Evaluation Form and the accompanying sample form.

NON-EPA TEST METHODS: Attach all test methods that are referenced in 

your rule that do not appear in 40 CFR 51, 60, 61, 63, or have not been 

previously submitted to EPA. EPA methods used in other media such as 

SW846 for solid waste are not automatically approved for air pollution 

applications. Submittal of test methods that are not EPA-approved should 

include the information and follow the procedure described in Region 9’s “Test 

Method Review & Evaluation Process.”

MODELING SUPPORT: Provide if appropriate. In general, modeling support is 

not required for VOC and NOx rules to determine their impacts on ozone 

levels. Modeling is required where a rule is a relaxation that affects large 

sources (> 100 TPY) in an attainment area for SO2, directly emitted PM10, 

CO, or NOx (for NO2 purposes). In cases where EPA is concerned with the 

impact on air quality of rule revisions which relax limits or cause a shift in 

emission patterns in a nonattainment area, a reference back to the approved 

SIP will be sufficient provided the approved SIP accounts for the relaxation 

and provided the approved SIP used the current EPA modeling guidelines. If 

current EPA modeling guidelines were not used, then new modeling may be 

required.

ECONOMIC AND TECHNICAL JUSTIFICATION FOR DEVIATIONS FROM 

EPA POLICIES: The District staff report or other information included with the 

submittal should discuss all potential relaxations or deviations from RACT, 

RACM, BACT, BACM, enforceability, attainment, RFP, or other relevant EPA 

requirements. This includes, for example, demonstrating that exemptions or 

emission limits less stringent than the presumptive RACT (e.g., a CTG) meet 

EPA’s 5 percent policy, and demonstrating that all source categories 

exempted from a RACM/BACM rule are de minimus according to EPA’s 

RACM/BACM policy.

ADDITIONAL MATERIALS: Provide District staff reports and any other 

supporting information concerning development of the rule or rule changes. 

This information should explain the basis for all limits and thresholds 

contained in the rule.
