SIP COMPLETENESS CHECKLIST

(Electronic Format)

*** TO BE COMPLETED BY DISTRICT AND RETURNED TO ARB ***

All rules submitted to the EPA as State Implementation Plan (SIP) revisions must be supported by certain information and 

documentation for the rule packages to be deemed complete for review by the EPA. Rules will not be evaluated for 

approvability by the EPA unless the submittal packages are complete. To assist you in determining that all necessary 

materials are included in rules packages sent to the ARB for submittal to the EPA, please fill out the following form and 

include it with the rule package you send ARB. See the ARB's Guidelines on the Implementation of the 40 CFR 51, 

Appendix V, for a more detailed explanation than is provided here. Adopted rules and rule amendments should be checked 

against U.S. EPA's Guidance Document for Correcting Common VOC & Other Rule Deficiencies (Little Blue Book, August 

21, 2001) to ensure that they contain no elements which will result in disapproval by EPA.

District: Imperial County APCD

ADMINISTRATIVE MATERIALS

Note: All documents should be in electronic format. Items that have signatures, initials, or stamps may be scanned.

Not

Attached Attached N/A

COMPLETE COPY OF THE RULE: Provide an unmarked copy of the entire rule 

as adopted or amended by your District Board.

UNDERLINE AND STRIKEOUT COPY OF THE RULE: If an amended rule, 

provide a complete copy of the rule indicating in underline and strikeout format 

all language which has been added, deleted, or changed since the rule was last 

adopted or amended.

COMPLETE COPY OF THE REFERENCED RULE(S): For any rule which

includes language specifically referencing another rule, a copy of that other rule 

must also be submitted, unless it has already been submitted to EPA as part 

of a previous SIP submittal.

PUBLIC NOTICE EVIDENCE: Include a copy of the local newspaper clipping 

certification(s), stating the date of publication, which must be at least 30 days 

before the hearing. As an alternative, include a copy of the actual published 

notice of the public hearing as it appeared in the local newspaper(s). In this 

case, however, enough of the newspaper page must be included to show the 

date of publication. The notice must specifically identify by title and number 

each rule adopted or amended.

RESOLUTION/MINUTE ORDER: Provide the Board Clerk certified resolution or 

minute order. This document must include certification that the hearing was 

held in accordance with the information in the public notice. It must also list 

the rules that were adopted or amended, the date of the public hearing, and a 

statement of compliance with California Health and Safety Code Sections

40725-40728 (Administrative Procedures Act).

PUBLIC COMMENTS AND RESPONSES: Submit copies of written public 

comments made during the notice period and at the public hearing. Also

TECHNICAL MATERIALS

Note: All documents and forms should be in electronic format.

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.

Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

Rule 805 is one of a series of seven rules which together form Regulation VIII, Fugitive Dust Control. On August 11, 

2004 the Imperial County was redesignated as a "serious"non attainment area for PM10. This rule, as an integral 

part of regulation VIII, was adopted to help fullfill the requirement of Best Available Control Measures (BACM.) Rule 

805 applies to paved, unpaved, construction road project, and road modification projects.

factor(s) and other information. Attach calculation sheet showing how the emission information provided below was determined.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Source Category: 10.12 tons/year

Inventory Year Used to Calculate Changes in Emissions: 2004 Area Affected: ICAPCD

Future Year Control Profile Estimate (Provide information on as many years as possible):

Rule 805 applies to unpaved and paved roads. Of the 7813 miles of unpaved roads in Imperial County, 1362 miles are city 

and county roads, 6312 miles are canal roads, and 139 miles area federal roads. 25.5 percent of enterained emissions and 

5 percent of windblown emissions are estimated to come from city and county roads over 50 ADT, which total 217 miles. 

Canal roads in total are estimated to contribute 67 percent of the windblown emissions and 53 percent of the entrained 

emissions. It is assumed that 0.5 percent of canal roads have 20 ADT or greater, and would thus be subject to Rule 805. 

Total applicability for unpaved roads result in an overall applicability percentage of 20 percent. The composite control factor 

is estimated to be 60 percent, assuming that both the County and canal roads will choose gravelling to meet the 

requirements of Rule 805.
