### Subtitle 11 AIR QUALITY

Notice of Proposed Action

[07-321-P-I] The Secretary of the Environment proposes to:

(1) Amend Regulation .30 under COMAR 26.11.19 Volatile Organic Compounds from Specific Processes ; and **PROPOSED ACTION ON REGULATIONS 2298** 

**MARYLAND REGISTER, VOL. 34, ISSUE 26 FRIDAY, DECEMBER 21, 2007**(2) Adopt new Regulations .01 — .07 under a new chapter, COMAR 26.11.35 Volatile Organic Compounds

from Adhesives and Sealants

.

Statement of Purpose The purpose of this action is to establish emissions limitsfor adhesive application and manufacturing operations under COMAR 26.11.19.30 and volatile organic compounds(VOC) standards for over 40 categories of adhesives, sealants, adhesive primers, sealant primers, and cleaning solvents under new chapter COMAR 26.11.35.

This action will be submitted to the U.S. EnvironmentalProtection Agency as a revision to Maryland’s State Implementation Plan (SIP).

Background

Adhesives and Sealants

Adhesives, sealants, adhesive primers, and sealant primers are used in manufacturing, packaging, construction, andinstallation of materials such as metal, wood, rubber, plastic, ceramics, fiberglass, and composites. An adhesive is a

material used to bond two surfaces. A sealant is a material with adhesive properties that is used primarily to fill and seal durably openings between two surfaces. VOC emissionsresult from evaporation of solvents during surface preparation, transfer, application, drying, and cleaning operations. Solvents solubilize the adhesive, sealant, or primer material for application and prepare the surface to provide a strongerbond. Solvents are also used to clean surfaces and equipment.

Existing Maryland Requirements

COMAR 26.11.19.15 Paint, Resin, and Adhesive Manufacturing and Adhesive Application specifies standards for honeycomb core manufacturing, footwear manufacturing, and spiral tube impregnating operations. Under COMAR 26.11.19.15C(4) General Emission Standard, up to 50 pounds per day of VOC emissions are allowed before a 3.8pounds per gallon VOC limit or an 80 percent overall control requirement applies. The proposed new regulations under COMAR 26.11.35 for adhesives and sealants will replace COMAR 26.11.19.15C(4) effective January 1, 2009. COMAR 26.11.19.30 Control of Volatile Organic Compoundsfrom Chemical Production and Polytetrafluoroethylene Installations contains requirements for the control of VOC emissions from adhesives and sealants and exempts small source emissions from controls. This regulation establishes VOC standards for installations exceeding 20 pounds/day and requires emission controls for installations above 50 pounds/day.

Basis for Adhesive Standards

The basis for the adhesive and sealant regulations is aregional model rule developed by staff of member states, including Maryland, and the Ozone Transport Commission (OTC) in 2006. The model rule itself was based in large part upon the reasonably available control technology (RACT)and best available retrofit control technology (BARCT) determination developed in 1998 by the California Air Resources Board (CARB). Based upon a review of those standards and comments received at public meetings, the OTC states finalized a model rule suitable for implementation in the Northeast in early 2007. The proposed adhesive and sealant regulations reflect amendments to the OTC modelrule made by the Department in response to comments received during the Maryland stakeholder process. Requirements of the Amendments and New Regulations The proposed action:

(1) Expands COMAR 26.11.19.30 to include fluoropolymer materials and establishes emission limits from adhesive application and manufacturing; and (2) Adopts new regulations, effective January 1, 2009, under new chapter COMAR 26.11.35 that: (a) Set standards for the application of adhesives,sealants, adhesive primers, and sealant primers by providing options for appliers either to use a product with a VOC content equal to or less than a specified limit or to use add-on controls; (b) Establish standards for cleanup solvents;(c) Establish a VOC limit for surface preparation solvents; (d) Provide for an alternative add-on control system requirement of at least 85 percent overall control efficiency (capture and destruction), by weight; (e) Provide exemptions for certain operations such as medical and defense equipment manufacturing and for small containers; (f) Require simplified records of materials used andVOC content to be maintained for 5 years, with more detailed records required for noncompliant products on material usage from persons who qualify for exemptions; (g) Require that VOC-containing materials must be stored or disposed of in closed containers;(h) Prohibit the sale of any adhesive, sealant, adhesive primer, or sealant primer that exceeds the VOC content limits; (i) Require manufacturers to label containers withthe maximum VOC content as supplied, as well as the maximum VOC content on an as-applied basis when used in accordance with the manufacturer’s recommendations regarding thinning, reducing, or mixing with any other VOC containing material; and (j) Prohibit the specification of any adhesive, primer,or sealant that violates the provisions of the proposed regulations.

Exemptions

Several adhesive and sealant applications and productsare exempt from the proposed regulations: tire repair, assembly and manufacture of components for undersea-basedship and weapon systems, electronic systems and subsystems for defense and homeland security, testing andevaluation associated with research and development, solvent welding operations for medical devices, plaque laminating operations, products or processes subject to COMAR 26.11.19.15, 26.11.19.30, or 26.11.32, small containers (net volume of 16 fluid ounces or less, or net weight of 1 pound),and low-VOC products (less than 20 grams/liter). The proposed regulations also provide an exemption for adhesive application operations at stationary sources that use lessthan 55 gallons per calendar year of noncomplying adhesives and for stationary sources that emit not more than 200 pounds of VOCs per calendar year.

Affected Sources

The proposed action applies to a person who, on or afterJanuary 1, 2009, sells, supplies, offers for sale, or manufactures for sale in the State any adhesive, sealant, adhesiveprimer, or sealant primer for use in the State or uses or applies, for compensation or facilities maintenance, an adhesive, sealant, adhesive primer, or sealant primer within the

State. **PROPOSED ACTION ON REGULATIONS 2299**

**MARYLAND REGISTER, VOL. 34, ISSUE 26 FRIDAY, DECEMBER 21, 2007**Emissions Reductions ExpectedThe technical analysis conducted through the OTC estimated that the model rule would achieve emission reductions corresponding to about 64 to 78 percent reduction from

uncontrolled levels. The emission reduction estimate forMaryland, based on the lower end of this range, is approximately 6 tons per day of VOCs in 2009.

Comparison to Federal StandardsThere is no corresponding federal standard to this proposed action.

Estimate of Economic Impact

I. Summary of Economic Impact . The cost impact of the adhesives regulations ranges from a savings of approximately $1,000 per ton to a cost of $2,500 per ton of VOC reduced. These costs arelikely to be less in this region because some of the costs reflect onetime research and reformulation costs incurred for products sold in

California.

II. Types of Economic Impact. Revenue (R+/R

) Expenditure (E+/E

) Magnitude

A. On issuing agency:

(1) Initial administrative cost (E+) $10,500 (2) Annual cost (E+) $23,000 B. On other State agencies: (E+) Minimal C. On local governments: (E+) Minimal

Benefit (+)

Cost (

) Magnitude

D. On regulated industries or trade groups: (

) Less than $2,500 per ton

of VOC reduced

E. On other industries or trade groups: (

) Minimal

F. Direct and indirect effects on public: (1) Cost (

) Minimal
(2) Health benefits (+) Undeterminable

III. Assumptions . (Identified by Impact Letter and Number
from Section II.)

A(1). This estimate of an initial administrative cost of approximately $10,500 is based on projected utilization of resources in calendar year 2008.

A(2). The estimate of $23,000 represents roughly one-half of afull-time equivalent salary in 2009. This workload will be addressed through the reallocation of existing resources.

B. and C. State and local agencies are not expected to incur significant incremental costs for the use of regulated materials. Reformulated products have been developed and are in use in the California market and can be transitioned to Maryland. Streamlined record keeping provisions are expected to minimize administrative

costs.

D. Manufacturers of adhesives and sealants that supply national markets reformulated their products to meet the standards of the California Air Resources Board (CARB), which have been in effect in California for several years. CARB estimated that the cost perton of VOC reduced varied between an expense of $2,500 to a savings of $1,000. Actual reformulation costs are likely to be lower in this region because the estimated costs reflected one-time research and reformulation costs incurred for products sold in California. In addition, exemptions under the proposed action provide flexibilityand reduce the cost of compliance. Streamlined recordkeeping provisions are expected to minimize the administrative costs associated with demonstrating compliance with the standards.

E. The economic impact of the proposed action upon other industries and trade groups is minimal, as national manufacturers havebeen producing compliant products to meet these standards in California for several years. F(1). The economic impact of the proposed action upon the general public is minimal, as national manufacturers have been producing compliant products to meet the standards in California for several years.

F(2). The expected reduction in emissions will help improveMaryland’s air quality and will result in fewer negative health effects on the general public from air pollution.

Economic Impact on Small Businesses The proposed action has minimal or no economic impact

on small businesses.

Impact on Individuals with Disabilities The proposed action has an impact on individuals withdisabilities as follows: This action will have a positive impact on individuals with disabilities involving respiratoryproblems by reducing air pollutants that contribute to disease.
