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

Rule 243 applies to any person in Placer County who (a) manuf actures, sells offers for sale or supplies polyester

resins for use in the District, or (b) uses polyester resins. Touchup and repair activities and low quantity users of

polyester resins (less than 20 gallons per month) are exempt from the rule.

The rule identifies the allowable spray application equipment.

The rule requires stationary sources to meet at least one of the following:

1. Low VOC polyester resin materials. Resins (except for specialty resins and gel coats) are not to exceed

35% by weight, as applied. Pigmented gel coats are not to exceed 45% by weight, as applied. Specialty resins

and clear gel coats are not to exceed monomer content of 50% by weight, as applied or,

2. Vapor Suppressant. Use polyester resin material containing a vapor suppressant which limits weight loss

from VOC emissions to no more than 60 grams per square meter or,

3. Closed Mold. Use a closed mold system or,

4. Installation of an emission control system with an overall control efficiency of 85% or greater.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: The rule was included as a VOC control measur e in the Sacramento Area Regional Ozone Attainment Plan,

which was adopted by the Distri ct Board on December 20, 1994. VOC emissi ons are precursors to the photochemical

formation of Ozone. The Attainment Plan was adopted in response to the 1990 Amendments to the Federal Clean Air Act

(CAA), which required areas designated “s erious” for Ozone by the United Stat es Environmental Protection Agency

(USEPA), to submit a State Implementation Plan (SIP) revision.
