Notice of Proposed Action

[09-407-P] The Secretary of the Environment proposes to amend Regulation .15 under COMAR 26.11.19 Volatile Organic Compounds from Specific Processes

.

Statement of PurposeThe purpose of this action is to repeal the general emission standard for adhesives under COMAR 26.11.19.15C(4)and replace it with the proposed source-specific VOC Reasonably Available Control Technology (RACT) emission limitation for the application of adhesives and sealants to specialty electronic systems and subsystems for defense andhomeland security. This source category is exempt from requirements under COMAR 26.11.35.

This action will be submitted to EPA for approval as part of Maryland’s State Implementation Plan. Background:

In 2008, Maryland established standards for adhesives

and sealants under COMAR 26.11.35 Control of VOC Emissions from Adhesives and Sealants, based on the 2006 Ozone Transport Commission (OTC) model rule. The OTCrule was developed using the 1998 RACT and a best available retrofit control technology determination by the California Air Resources Board as guidance.

Adhesives, sealants, adhesive primers, and sealant primers are used in manufacturing, packaging, construction, andinstallation of such disparate materials as metal, wood, rubber, plastic, ceramics, fiberglass and composites. An adhesive is any 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. The standards in COMAR 26.11.35 reflect the large-scale use of

adhesives and sealants for different materials.

Adhesives used for specialty electronic systems and subsystems for defense and homeland security are developed, tested, and manufactured on a small scale. The adhesivesare unique and vary significantly, which makes it very difficult to establish any VOC content standards. In lieu of specific emission standards for VOCs in this source category, aVOC RACT emission limitation is established in this regulation. Requirements of the Amendment:

This amendment establishes a RACT emission limitation for specialty electronic systems and subsystems for defenseand homeland security. The amendment limits the discharge into the atmosphere to not more than 25 pounds perday of VOC from adhesive and sealant application, averaged over a monthly period. Emissions Reductions Expected:

The proposed amendment is designed to provide a RACT emission limitation for the application of adhesives andsealants in developing, testing, and manufacturing specialty electronic systems and subsystems for defense and homeland security. No emission reductions are expected from the proposed amendment because the emissions limit

can be met without the addition or use of controls.

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

Estimate of Economic Impact

The proposed action has no economic impact.

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 no impact on individuals with

disabilities.

Opportunity for Public Comment The Department of the Environment will hold a public hearing on the proposed action on January 21, 2010, at 10a.m. at the Department of the Environment, 1800 Washington Boulevard, 1st Floor Aeris Conference Room, Baltimore,Maryland 21230-1720.

Authority: Environment Article, §§1-101, 1-404, 2-101 — 2-103,

Notice of Proposed Action

[09-411-P-I] The Secretary of the Environment proposes to amend Regulation .32 and adopt new Regulation .33 under COMAR 26.11.19 Volatile Organic Compounds from Specific Processes

. Statement of Purpose The purpose of this action is to adopt the requirements ofthe Environmental Protection Agency (EPA) Control Techniques Guidelines (CTG) for flat wood paneling coatings. EPA develops CTGs as guidance on control requirements for source categories. States can follow the CTGs or adopt morerestrictive standards. MDE proposes to adopt the CTG standards for flat wood paneling coatings.

This action will be submitted to the EPA for approval as part of Maryland’s State Implementation Plan. Background:

In June 1978, EPA published a final CTG for flat wood paneling coatings, entitled ‘‘Control of Volatile Organic Emissions from Existing Stationary Sources, Volume VII, Factory Surface Coating of Flat Wood Paneling’’. In 1979, EPA published guidance to provide assistance to State andlocal air pollution control agencies in preparing RACT regulations for a variety of categories, including flat wood paneling. In 2003, EPA promulgated national emission standards for hazardous air pollutants (NESHAP) covering surfacecoating of wood building products (including flat wood paneling).

A flat wood coating facility applies stains and varnishes tonatural plywood panels used for wall coverings. These facilities also print wood grain patterns on particle board panels that are first undercoated with an opaque coating to mask the original surface. Coatings applied to flat wood paneling include fillers, sealers, ‘‘groove’’ coats, primers, stains,basecoats, inks and topcoats. Generally, coatings are applied by direct roll coating. Filler is applied by reverse roll coating. The offset rotogravure process is used where the coating and printing operation requires precision printing. Other coating methods used include spray techniques, brush coating and curtain coating. A flat wood paneling coating line includes a succession of coating operations.Each individual operation consists of the application of coatings and a heated oven to cure the coatings.

The CTG applies to facilities that apply flat wood paneling coatings that emit 15 pounds or more per day (6.8 kg/day) of VOC before consideration of controls. Flat wood paneling coatings means paneling products that are any interior, exterior, or tileboard (Class I hardboard) panels to which a protective, decorative, or functional material or layer has been applied.

Work practice standards that have proven particularly effective include: (1) frequent visual inspections for all equipment used to transfer or apply coatings, adhesives, or organic solvents; (2) cleaning and wash-off solvent accountingsystem; (3) collecting and containing all VOCs when cleaning coating lines and spray guns; and (4) using low-VOC or low-vapor pressure cleaning materials.

Affected Sources:

The proposed regulation develops standards for flat wood paneling coating operations. Facilities that apply stains and varnishes to natural plywood panels used for wall coverings are affected by this regulation. Regulation Summary:

Regulation .33 sets a VOC standard of 2.1 pounds of VOC per gallon (250 grams VOC per liter) upon surface coatings, inks, or adhesives applied to flat wood panelings.

Affected sources can comply with the coating standards orcontrol emissions by 90 percent. The work practice requirements establish standards for the usage of all VOC containing materials. Expected Emissions Reductions: **PROPOSED ACTION ON REGULATIONS 2074**
