RULE CONSISTENCY ANALYSIS

I. REQUIREMENTS FOR RULE CONSISTENCY ANALYSIS

Prior to adopting, amending, or repealing a rule or regulation, California Health and 

Safety Code Section 40727.2 requires that District staff perform a written analysis that 

identifies and compares the air pollution control elements of the proposed rule with the 

corresponding elements of existing or proposed District and United States 

Environmental Protection Agency (EPA) rules, regulations, and guidelines that apply to 

the affected source category. The elements that were analyzed are emission limits; 

work practices; monitoring and testing; and recordkeeping and reporting requirements. 

The analysis is detailed in Section II of this report. Conclusions based on the analysis 

are shown in Section III.

II. RULE CONSISTENCY ANALYSIS

District staff reviewed EPA rules, regulations, and guidelines, as well as District rules for 

the source categories covered by the eleven District rules in this rule project. The 

analysis was confined to those provisions that refer to solvent cleaning for the particular 

source category. Emission limits, operating parameters, monitoring, testing, records, 

and reporting requirements from processes other than solvent cleaning associated with 

the source category were ignored for purposes of the rule consistency analysis. 

A. Existing or Proposed District Rules

There is only one District rule that has solvent cleaning requirements that is not part of 

this rule project – Rule 4602 (Motor Vehicle and Mobile Equipment Coating Operations). 

The provisions of this rule will no longer be in force as of January 1, 2009, so District staff

chose not to change any requirements in this rule. It should be noted that Rule 4602 will 

be superseded by Rule 4612 (Motor Vehicle and Mobile Equipment Coating OperationsPhase II) on and after January 1, 2009. Rule 4612 is being amended as part of this 

current rulemaking project to incorporate the provisions of solvent cleaning operations.

B. Existing or Proposed Federal Rules, Regulations, and Guidelines

1. Control Techniques Guidelines (CTGs)

There are five CTGs that have solvent cleaning provisions. These applicable CTG are 

listed in Table 1.

CTG Number

CTG Title Operation Covered

EPA-450/2-77-022

Control of Volatile Organic Emissions from Solvent Metal 

Cleaning

Facilities that use a degreaser to clean

EPA-453/R-97-004

Control of Volatile Organic Compound Emissions from Coating 

Operations at Aerospace Manufacturing and Rework Operations

Facilities that have coating operations for 

aerospace manufacturing and rework

EPA-453/R-06-001

Control Techniques for Industrial Cleaning Solvents

Cleaning with solvent in industrial settings

EPA-453/R-06-002

Control Techniques Guidelines for Offset Lithographic Printing 

and Letterpress Printing

Lithographic and letterpress printing

EPA-453/R-06-003

Control Techniques Guidelines for Flexible Package Printing

Flexible packaging printing

The CTG for solvent metal cleaning relates to degreasers. Rule 4662 addresses these 

units. Because this CTG was approved in 1977, all of the requirements related to 

solvent degreasers have been incorporated into Rule 4662 by previous rule projects.

The CTG for cleaning in industrial settings recommends a general VOC content limit of 

50 g/L with some exceptions, mostly for cleaning of printing equipment. This rule 

project incorporates a VOC content of 25 g/L for most cleaning operations, which is 

lower than the CTG-recommended content limit. 

The CTG for offset lithographic/letterpress printing and the CTG for flexible packaging 

printing contain work practices for minimizing emissions from solvent cleaning, but no 

specific VOC content limit. The work practice recommended by the CTG is already 

contained in the solvent cleaning portion of Rule 4607 (Graphic Arts), the District rule 

that covers printing operations. Therefore, solvent cleaning portion of Rule 4607 does 

not conflict with the two CTGs related to printing.

2. New Source Performance Standards (NSPS)

NSPS requirements are organized by source category in 40 CFR Part 60. The District 

has incorporated the NSPS by reference, meaning that District Rule 4001 lists all of the 

NSPSs and the requirements of these NSPSs have been adopted without change the 

District. District Rule 4001 lists 71 NSPSs. None of these NSPSs has solvent cleaning 

as part of its requirements. Therefore, this rule project is neither inconsistent with nor 

conflicts with any requirement of an NSPS.

3. National Emission Standards for Hazardous Air Pollutants (NESHAPs)

NESHAPs are requirements contained in 40 CFR 61 and 40 CFR 63. As with the 

NSPSs, the District has incorporated the requirements of the NESHAPS into its rules 

and District Rule 4002. There are no NESHAPs in 40 CFR 61 with solvent cleaning 

requirements. Table 2 lists the NESHAPs from 40 CFR 63 with solvent cleaning 

provisions. Of the NESHAPs in Table 2, 40 CFR 63 Subpart T applies to District Rule 

4663 for solvent degreasers. The District rules that apply to the source categories for 

the remaining NESHAPs all have solvent cleaning requirements in District Rule 4662 

(Organic Solvent Cleaning), which is the general solvent-cleaning rule.

40 CFR 63

Subpart:

Source Category

T Halogenated Solvent Cleaning

GG Aerospace Manufacturing and Rework

WW Boat Manufacturing - Resin and Gel Coat Application Equipment Cleaning Operations

III Flexible Polyurethane Foam Production

In complying with the District rules for the above source categories, there is no conflict 

with NESHAP.

III. RESULTS OF RULE CONSISTENCY ANALYSIS

District staff found that facilities could comply with the proposed amendments to the 

solvent cleaning portions of the eleven District rules as well as all other existing or 

proposed District rules. Furthermore, District staff found that none of the proposed 

requirements of for this rule project would conflict with federal rules, regulations, or 

policies covering similar stationary sources.
