April 16, 2011 BASIS STATEMENT In the State of Maine, nine counties are classified as nonattainment for the federal ozone air quality standard. Ground-level ozone formation is caused in part by surface coating operations that emit volatile organic compounds (VOC) . This regulation of surface coating facilities restricts the VOCemissions fromselected surface coating operations. Under Section 184 ofthe CleanAir Act Amendments of 1990, the State of Maine must submit plans to control VOCfromall sources covered bya Control Technique Guideline (CTG) issued before November 15, 1990.

In addition to the Basis Statement above, the Department has filed with the Secretary of State its response to comments received during the comment period.

BASIS STATEMENT FORAMENDMENTS OF JANUARY 28,1998 These amendments simplify compliance for surface coating facilities through the establishment of an exemption for the use of coatings used on-site for maintenance and repair activities, and a de minimus threshold. The amendments also remove the once-in, always-in provisions for sources accepting certain license restrictions, establish explicit work practice standards for the use of solvents in cleanup operations, and incorporate the Federal MACT requirements for several surface coating categories. In addition to this Basis Statement, the Department has filed a supplemental Basis Statement with the Secretary of State that summarizes its responses to comments received during the comment period.

BASIS STATEMENT FORAMENDMENTS OF JANUARY 6, 2011 In the late 1970's, EPA published CTGs recommending VOCcontrols for flat wood paneling and metal furniture, which were updated in September 2006 and September 2007, respectively. The amendments expand the types of paneling regulated by Chapter 129 to include exterior siding and tileboard. Emission limits for these two categories were not addressed in the 1978 CTGdocument . The amendments lower the threshold above which sources are subject to the rule to 15 lbs/day of VOC (from 10 tons per year) . VOC emission limits are expressed in weight pervolume units instead of a weight per surface area coated. The amendments provide VOC limits for eight types of coatings used on metal furniture and list 6 coatings that are exempt from the rule. The amendments lower the threshold to 15 lbs/day (from10tons per year) above which metal furniture sources are subject to VOCcontrols . In addition to this Basis Statement, the Department has filed a supplemental Basis Statement with the Secretary of State that summarizes its responses to comments received during the comment period.

(a) Determining the efficiency ofvolatile organic compound (VOC) capture systems. (1) For purposes ofthis paragraph, thefollowing definitions and abbreviations apply: "Gas/gas method" means either of two methods for determining capture that rely only on gas phase measurements. One method requires construction of a temporary total enclosure (TTE) to ensure all potential fugitive emissions are measured while the other method uses the roomor building that houses the source as an enclosure. "Hood" means a partial enclosure or canopy for capturing and exhausting, by means of a draft, the organic vapors or other fumes rising froma coating process or other source. "Liquid/gas method" means either of two methods for determining capture that require both gas phase and liquid phase measurements and analysis. One liquid/gas method requires construction of a temporary enclosure, and the other uses the building or room that houses the facility as an enclosure. "Process line" means any coating unit, coating line, coating operation, or printing press. "PTE" is a permanent total enclosure, which contains a process that emits VOC and meets the specifications given in Chapter 126Appendix A Procedure T. "TTE" is a temporary total enclosure that is built around a process that emits VOCand meets the specifications given in Chapter 126Appendix A Procedure T. "BE" is a building or roomenclosure that contains a process that emits VOC . If a BE is to substitute for a PTE or TTE, the appropriate requirements given in Chapter 126 Appendix A Procedure T shall be met . (2) Applicability. (i) The requirements of paragraph (a)(3) shall apply to all regulated VOC emitting processes using a control systemexcept as provided below . (ii) If a source owner or operator installs a PTE that meets EPA specifications, and that directs all VOC to a control device, the capture efficiency is assumed to be 100 percent, and the source is exempted from the requirements described in paragraph (a)(3) . Chapter 126Appendix A Procedure T shall be used to determine whether a structure is a PTE. This does not exempt a source from performing any control device efficiency testing required under this subpart . In addition, a source shall demonstrate that all criteria for a PTE are met during the testing for capture efficiency.

### 10 (iii) If a source owner or operator uses a control device designed to collect and recover VOC (e.g., carbon adsorber), an explicit measurement of capture efficiency is not necessary if the conditions given below are met . The overall emission reduction efficiency of the control systemshall be determined each day by directly comparing the input liquid VOC (liters) to the recovered liquid VOC . The procedure for use in this situation is specified in 40CFR60.433 with the following modifications : (A) The source owner or operator shall obtain data each day for the solvent usage and solvent recovery and determine the solvent recovery efficiency of the systemeach day using a 7-day rolling period. The recovery efficiency for each day is computed as the ratio of the total recovered solvent for that day and the prior 6 consecutive operating days to the total solvent usage for the same 7-day period used for the recovered solvent, rather than a 30-day weighted average as given in 40 CFR 60.433. This ratio shall be expressed as a percentage. This shall be done within 72 hours following each 24-hour period, and (B) If the solvent recovery systemcontrols multiple process lines, the source owner or operator shall demonstrate that the overall control (i .e., the total recovered solvent VOC divided by the sum of liquid VOC input to all process lines venting to the control system) meets or exceeds the most stringent standard applicable for any process line venting to the control system . Specific Requirements. (i) The capture efficiency shall be measured using one ofthe four protocols given in paragraphs (a)(3)(iii)(A) through (a)(3)(iii)(D) of this section. During any capture efficiency test, the average face velocity of each emissions collection point ducted to the control device shall be measured and recorded. In addition, the distance between each collection point ducted to the control device and the emission source shall be measured and recorded. Measurements of average face velocity shall be done by determining average volumetric flowrate using, Reference Method 2, 2Aor 2C of 40 CFR Part 60, Appendix Aand dividing by the total area of the face of the collection point. (ii) Any error margin associated with a test protocol may not be incorporated into the results of a capture efficiency test. (iii) Any source required to comply with this section shall use one of the following protocols to measure capture efficiency, unless a suitable alternative protocol is approved by the Department and EPA : (A) Gas/gas method using TTE. Chapter 126Appendix A Procedure T shall be used to determine whether a temporary enclosure is a TTE. The capture efficiency equation to be used for this protocol is:



# Gw CE _ Gw+Fw

### 11

CE = capture efficiency, decimal fraction; Gw = mass of VOCcaptured and delivered to control device using a TTE; and Fw = mass of fugitive VOCthat escapes froma TTE. Chapter 126AppendixA procedures are used to obtain Fw & Gw . (B) Liquid/gas method using TTE. Chapter 126 Appendix A Procedure T shall be used to determine whether a temporary enclosure is a TTE. The capture efficiency equation to be used for this protocol is: 

# e-I L - F E = L CE = capture efficiency, decimal fraction; L = mass of liquidVOCinput to process; and F = mass of fugitive VOCthat escapes froma TTE. Chapter 126Appendix Aprocedures are used to obtain L and F. (C) Gas/gas method using the building or room(BE) in which the source is located as the enclosure and in which G and F are measured while operating only the source to be tested. All fans and blowers in the building or roomshall be operated as they would be under normal production. The capture efficiency equation to be used for this protocol is: 

# CE = G G + FB

CE = capture efficiency, decimal fraction; G = mass of VOCcaptured and delivered to a control device; and FB = mass of fugitive VOCthat escapes frombuilding enclosure. Chapter 126Appendix A procedures are used to obtain G and FB. (D) Liquid/gas method using the building or room(BE) in which the source is located as the enclosure and in which L and F are measured while operating only the source to be tested. All fans and blowers in the building or roomshall

### 12 be operated as they would under normal production. The capture efficiency equation to be used for this protocol is: 

# CE = L FB

L where: 

### CE = capture efficiency, decimal fraction; L = mass of liquid VOCinput to process; and FB = mass of fugitive VOCthat escapes from building enclosure. Chapter 126 Appendix Aprocedures are used to obtain L and FB. (4) Recordkeeping and Reporting. (i) All sources complying with this section shall maintain on file a copy of the capture efficiency protocol submitted to the Department . All results of appropriate test methods and CE protocols shall be reported to the Department within 60days of the test date. Acopy ofthe results shall be kept on file with the source. (ii) If any changes are made to capture or control equipment, the source is required to notify the Department in writing within 30 days of these changes and a newcapture efficiency and/or control device destruction or removal efficiency test may be required. Achange to the capture or control equipment shall be defined as any modification to or malfunction of the capture systemor control systemthat increases the distance between any emissions collection point and the emissions source that the collection point is serving or that reduces the average face velocity at any emissions collection point ducted to the control device to a value less than 90%ofthe value measured and recorded during the capture efficiency test.
