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

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 Purpose

The 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 and

homeland 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 OTC

rule 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, and

installation 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 adhesives

are 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, a

VOC 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 defense

and homeland security. The amendment limits the discharge into the atmosphere to not more than 25 pounds per

day 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 and

sealants 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 Standards

There 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.

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 of

the 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 more

restrictive 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 and

local 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 surface

coating of wood building products (including flat wood paneling).

A flat wood coating facility applies stains and varnishes to

natural 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 accounting

system; (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 or

control emissions by 90 percent. The work practice requirements establish standards for the usage of all VOC containing materials.

Expected Emissions Reductions:
