DearMr. Conroy: PATRICIA W. AHO COMMISSIONER



### Enclosedplease fmd for your approval and inclusion into Maine's State hnplementation Plan (SIP), the recently adopted Chapter 162 Control for Fiberglass BoatManufactoring Materials rule. This new rule limits the emissions ofvolatile organic compounds (VOC) from fiberglass boatbuilding operations during the manufacture and repair offiberglass boats. These rules were adopted pursuant to Section 184 ofthe federal Clean 

### AirAct, which requires states to implement orupdate reasonably available control technology (RACT) controls on all major emission sources, and on source categories coveredby a Control Technique Guideline (CTG) document. A public hearing was held on April2, 2013, in accordance with federal and state administrative requirements. Public notice ofthe hearing was published inthe Kennebec Journal onMarch 2, 2013 and in newspapers statewide onMarch 13, 2013. On July 19, 2013, the Commissioner ofthe Department of Environmental Protection adopted Chapter 162. The following administrative materials are enclosed: 1. Copy ofthe public notice that appeared onMarch 2, 2013 inthe Kennebec Journal; 2. Copy ofletter from U.S. EPA dated March 27, 2013 indicating thatthe proposal is consistent with EPA's "Control Techniques Guidelines for Fiberglass BoatManufacturing Materials" (there were no other comments); 2. The Department's Chapter 162 Control for Fiberglass Boat Manufacturing Materials rule; and 3. MAPAI form for Chapter 161 providing certification that the Connuissioner ofthe Department of Environmental Protection lawfully adopted this rule onJuly 19, 2013, and certification that the Attorney General approved the rule as to form and legality. The Department is also submitting exact electronic copies (pdf) ofall enclosed materials. Should you have any questions, please contact Jeffrey Crawford at (207) 287- 7647.

5:00P.M. BRIEF *SUMMARY: The Department is proposing a new rule that will limit the emissions of volatile organic compounds (VOC) from fiberglass boatbuilding operations during the manufacture and repair of fiberglass boats. Fiberglass boatbuilding operations use polyester and viny!ester resinstofabricate the var- ious components of boats using molds that provide the desired shape for the finished products. Open molding operations, which are most commonly used in fiberglass boatbuilding, release significant amounts of VOC, predominately styrene, during the curing process. These rules are being proposed to pursuant to Section 184 ofthefederal Clean Air Act, which re- quires states to imple- ment or update reason- ably available control technology (RACT) con- trols on all major emission sources, and on source categories cov- ered by a Control Tech-

. Guideline 2008, the U.S. Environmental Protection Agency published a CTG for fiberglass boat manu- facturing materials that recommends control options for this source cate- gory. Maine's proposed rule isbased on theserec- ommendations, and re- duces VOC emissions from larger boatbuilding sources with 5400 pounds per 12-month period or greater emissions. These amendments will be submitted to EPA for approval in Maine's State Implementation Plan. Copies of these rules are available upon requestby contacting the AgE!ncy contact person or on the DEP website at www. maine.gov/dep/rules/.

### Maine Dept. ofEnvironmental Protection 17 State House Station Augusta, ME 04333 Dear Mr. Crawford: The Maine Department ofEnvironmental Protection (ME DEP) is proposing a new regulation Chapter 162 "Control for Fiberglass Boat Manufacturing Materials," which will limitthe emissions ofvolatile organic compounds (VOCs) from fiberglass boat building operations during the manufacture and repair offiberglass boats. EPA previously reviewed a draft ofthe rule and sent written comments to the ME DEP in a letter dated September II, 2012. We have reviewed the proposed regulation and have found that the ME DEP 

### has adequately addressed ourprevious comments. The proposal is consistent with EPA's "Control Techniques Guidelines for Fiberglass Boat Manufacturing Materials" (EPA 453/R-08-004). We have no further comments on the proposed rule. Maine should submit Chapter 162 to the EPA as a State Implementation Plan revision once adopted by the State. Ifyou have any questions on this issue, please contact David Mackintosh ofmy staffat 617-918-1584. Sincerely,

Anne Arnold, Manager Air Quality Planning Unit06-096

### 4. Calculating emission rates for lilled resins (1) When using a filled production resin orfilled tooling resin, the owner or operator shall calculate the emissionrate for the filled material on an as-applied basis using Equation 5:

PVu = The monomer VOC emission rate for the neat (unfilled) resin before filler is added, as calculatedusing the formulas inTable 2 ofSection 3(B)(3) of this Chapter. %Filler= The weight-percent offiller in the as-applied filled resin system. (2) Ifthe filled resin: (1) Is used as a productionresin then the value ofPVp calculatedbyEquation 5 shall not exceed 46 kilograms ofmonomerVOCpermegagram offilled resin applied; (2) Is used as a tooling resin then the value ofPV F calculatedbyEquation 5 shall not exceed 54 kilograms ofmonomer VOC permegagram offilled resin applied; (3) Is included in the emissions averaging procedure then the facility shall use the value ofPVp calculatedbyEquation 5 for the value ofPV; in Equation 4 in Section 3(B)(3) ofthis Chapter. 

### 5. Non-monomer VOC content A. Up to five percent ofthe non-monomer VOC content ofa resin or gel coat shall be exempt from the VOC content limits ofthis Chapter.
B. Ifthe non-monomer VOC content limit ofa resin or gel coat exceeds five percent, then the excess non-monomer VOC over five percent shall be added to the monomer VOC content. The monomer VOC content ofresin and gel coat shall be determined byusing SCAQMD Method 312-9, Determination ofPercent monomer in polyester resins, revised 1996, unless the facility maintains records from the manufacturer to document the monomer VOC content ofresin and gel coat materials.

### B. Only non-volatile organic compound solvents shall be used to remove cured resin and gel coat from application equipment. 

### 7. Workpractice standards. All resin and gel coat containers with a capacity equal to or greater than 208 liters (55.0 gallons), including those used for on-site mixing ofputties and polyesterresin putties, shall have a cover with no visible gaps in place at all times. This work practice does not apply when materials are being manually added to orremoved from a container, or when mixing equipment is being placed or 

### removed from a container. 8. Testmethods and compliance procedures. The owner or operator ofany facility with open molding resin and gel coat operations choosing to use add-on emission controls pursuant to Section 3(C) ofthis Chapter shall perform compliance testing and demonstrate compliance using the methods and procedures described in Capture Efficiency Test Procedures, 06-096 CMR 126. The Department shall be notified 30 days prior to performing compliance testing, and test results shall bereported to the Department within 60 days after the test. A. When calculating the monomer VOC emission limitation in Section 3(B) ofthis Chapter, the owner or operator shall use the mass ofeach material used during the control device performance test (in lieu of the mass ofeach material used over the past twelve months) to determine the emission limit that is applicable during the test. Ifthe measured emissions at the outlet ofthe control device are less than the emission limit, then the facility will be considered to have achieved compliance with the emission limit. 

### B. Ifthe owner or operator is using a filled production resin ortooling resin, compliance shall be demonstrated for the filled material on an as-filled basis using equation 6: 

### Equation 6 

### (100

- percent filler) PVp=PVux

________ **~~-----** 100 Where: PV F = The as-applied monomerVOC emission rate for a filled productionresin or toolingresin, kilograms ofmonomerVOC perton offilled material. PV u = The monomerVOC emission rate for the neat (unfilled) resin, before filler is added, as calculatedusing the formulas in Table 2 ofthis Chapter. Per cent filler= The weight-per cent offiller inthe as-applied filled resin system. C. The owner or operator subject to this Chapter choosing to use add-on emission controls pursuant to Section 3(C) ofthis Chapter shall perform additional testing and submit a report within ninety (90) days ofreceipt ofnotice from the Department ifequipment operating parameters, staffinspection, air monitoring or other cause indicate to the Department that the surface coating facility may be operating out ofcompliance with the emission limitations.
