### I. INTRODUCTION The Massachusetts Department of Environmental Protection (MassDEP) proposes to amend its regulations for Volatile and Halogenated Organic Compounds, 310 CMR 7.18 (hereinafter referred to as the " proposed amendments ") to further reduce emissions of volatil e organic compounds (VOCs) from solvent metal degreasi ng operations
. These proposed amendments are part of Massachusetts' strategy to reduce ground-level ozone in order to meet the national 8-hour ozone air quality standard, for which Massachusetts is currently in nonattainment. This document provides background information on the proposed amendments
. 

### 3

Solvent metal degreasing operations emit a significant amount of VOCs. VOCs contri bute to the formation of ground- level ozone , or smog , which adversely affects publ ic health and damages forests and vegetation
. Many VOCs a lso are toxic and , at sufficient concentrations and exposure , are known to cause cancer or other serious health effects (such as reproductive effects or birth defects) and adverse environmental effects. Reducing VOC emissions from solvent metal degreasing operations will substantially benefit public health and the environment by reducing ground-level ozone and reducing worker exposure to toxic**chemic~ .**  

### · · To achieve this public health and environmental benefit, the proposed amendments lower the permissible vapor pressure of solvents used in cold degreasing operations. The proposed amendments are based on similar control measures that several other New England states already have adopted
. 

### II . BACKGROUND A. Ozone and Ozone Precursors Ground-level ozone is a photochemical oxidant that can cause lung dysfunction and eye, nose and throat irritation
. Ozone is formed when volatile organic compounds (VOCs) react with oxides of nitrogen (NOx) in the presence of sunlight and heat. Unhealthy concentrations of ozone occur most frequently during hot summer months. Ozone i rritates the respiratory system and may cause coughing and shortness of breath
. It also can exacerbate resp i ratory illness and reduce resistance to infection
. Ozone is of particular concern for children , people with asthma and other chronic respiratory diseases , and people exercisi ng and working outdoors for prolonged periods of time. Ozone also damages forests and other vegetation. agricultural crops, and natural and synthetic materials
. 

### B.' Massachusetts Ozone Non-Attainment Status Pursuant to the federal Clean Air Act (CAA), the U .S. Env i ronmental Protection Agency ( EPA) has establ ished health-based National Ambient Air Quality Standards (NAAQS) for six criteria pollutants: ozone; nitrogen dioxide; particulate matter; carbon monoxide; sulfur dioxide; and lead. Massachusetts is in attainment with all of the NAAQS except the 1997 8-hour ozone standard 1

. 

### Massachusetts has two ozone non-attainment areas. The western Massachusetts non-attainment area encompasses Hampden, Hampshire , Franklin and Berkshire counties. The eastern Massachusetts non-attainment area encompasses the remainder of the state. Both areas were classified as moderate non -attainment areas under the 1997 8-hour ozone standard
. Due to transport
. emissions in Massachusetts also contribute to violat ions of the 8-hour standard i n southern New Hampsh ire and Maine. Massachusetts submitted to EPA a State Implementation Plan (SIP) that demonstrates how it will attain the 1997 8-hour ozone standard statewide by 2010. The proposed amendments are part of MassDEP's

1 EPA promulgated th e 8-ho u r ozone standard in 1997to update the previous 1-hour ozone sta ndard , which EPA revoked i n 2005
. In Ma rch 2008 EPA revi sed the 8-hour ozone standard from 0
.08 parts per million (pp m ) to 0
.075 ppm . Massach usetts must subm it a recommendation to EPA by Ma rch 2009 regarding attainment status relative to the new revi sed ozone standard.

### 4 efforts to reduce emissions of ozone precursors in orde r to attain the 8-hour ozone standard by 2010, and the emission reductions from these amendments are reflected in the attainment modeling demonstration 

### in MassDEP's SIP submittal. These emission reductio ns, combined with emission reductions achieved in upwind states, are designed to bring Massachusetts into attainment with the 8-hour ozone standard. 

### C. Existing Massachusetts and Federal Regulations Massachusetts adopted its solvent metal degreasing regulation, 310 CMR 7.18(8), on December 31,

. 1980 as one .of many control programs designed to address nonattainment with the 1-hour ozone · standard that was in effect at that time. The regulation sets specific operation and maintenance standards to reduce emissions from solvent metal degreasing operations and is based on the Control Techn ique Guidel ines (CTG) published by E PA for this sector. These degreasing operations include cold cleaning deg reasing, vapor degreasi ng, and conveyorized degreasing. EPA regulates vapor degreasing operations that use halogenated o rganic compounds that are · considered hazardous air pollutants (HAPs, also referred to as air taxies), through its Maximum

### . f::iAPs also are .VOCs
.. .Therefore , the MACT**stan~ards**

### operations.



### . . 

### D. · Ozone Transport Commission Model Rule The Ozone Transport Commission (OTC) 2 

### developed a solvent cleani ng model rule in 2001, for use by states, to address 1-hour ozone nonattai nment throug ho ut the OTC region
. The OTC model rule establishes equipment, solvent, and operationa l req ui rements for metal solvent degreasing, and is based on EPA's MACT standards for ch lorinated solvent vapor degreasers
. (The MACT standards address use of chl ori nated solvents, some of which are classified as VOCs, but they do not address use of all VOCs in degreasers.) The OTC model rule estab l ishes a higher l evel of contro l than those suggested i n EPA's Control Techn ique Guidance (CTG) for th i s i ndustrY (i.e ., the EPA guidelines fo r degreasers that use VOCs)
. MassDEP's existing solvent metal degreasing regulation, 310 CMR 7.18(8) , is similar to the OTC solvent cleaning model rule in many respects and contains many of the emission controls and reporting requirements of the OTC model rule. Massachusetts did not need additional VOC reductions from solvent metal degreasing sector to address its attainment goals for the 1 -hour ozone standards
. However, as part of its 8-hour ozone SIP, MassDEP committed to adopti ng those additional requirements of the model rule that provide the greatest VOC emission reduction benefits
. According to an OTC report3 , 

### most of the emission reduction benefits that can be achieved from implementation of t he OTC's solvent clean ing model rule are atfri butt:!d to use of low-volatility cold cleaning solvents. Therefore, MassDEP is proposing to adopt only the OTC model rule's vapor pressure requirement for cold cleaning solvents rather than the model rule in its enti rety. MassDEP be l ieves that the costs associated with retrofitting existing vapor degreasers with all of the OTC model rule requirements outweighs the minimal VOC emission reduction benefits t hat would result. In addition, MassDEP believes that the existing Massachusetts rule contains sufficient reporting and recordkeep i ng requirements, and that imposing additional administrative
.requirements contained in the OTC model rule is unnecessary .

2 Section 1 84(a) of the CAA established the Northeast Ozone Transport Region (OTR) and the Ozone Transport Commission (OTC). The OTR is comprised of the District of Columbii!, a portion qf Northern Virginia , and the states of Mai n e , Vermont, New Hampshire , Massachusetts, Connecticut, Rohde Island, New York, Pennsylvania, New Jersey, Delaware, and Maryland. The CAA requires the OTC to assess the degree of interstate transport of ozone and its precursors throughout the OTR and recommend strategies that would help states in the OTR meet the NAAQS for ozone. 3 E
. H. Pechan and Associates, Control Measure Development Support Analysis of Ozone Transport Commission Model Rules, prepared for the Ozone Transport Commission , March 31 , 2001. The report states that emission reduct i ons achieved due to vapor cleaning and other cold cleaning operational requirements are minimal
. The report quantifies only the VOC emission red uctions due to use of low-volatility cold cleaning solvents
.

### 5
Ill. SUMMARY OF PROPOSED AM E NDMENTS The proposed amendments to 310 CMR 7.18{8) apply to any person who owns, operates , leases, or controls any solvent metal degreasing faci lity in Massach u setts. The proposed amendme nts requ i re that the vapo r pressure of the solvent used in a cold clean ing degrease r that is able to hold more than 1 liter of solvent not exceed 1.0 m illimete r of me rcury at 20 degrees Celsiu s. T he proposed amendments provide an exemption in the following cases: a . cold cleaning degreasers used i n speci al and extreme solvent metal cleaning ; or b. cold cleaning degreasers for which the owner or operator receives an approval from MassDEP that use of a compliant solvent will result in unsafe operating conditions ; or c. cold cleaning degreasers that are located in a J:)ermanent total enclosure having cont rol equ i p ment that i s desig n ed and ope rated with an overa ll VO C co ntro l efficiency of 90 percent o r g reater. The existing regulation, which will 

### be replaced by the proposed amendments, requires that the solvent is kept at a temperature below 50 degrees Celsius or that the vapor pressure of the solvent does not exceed 33 millimete rs of mercury at 38 degrees Celsius for cold cleaning degreasers that have a remote solvent reservoi r and have no covers. l.t also requires that the opening of the sink-like area in such degreasers 

### be less than 1 00 square centimeters
. Under 310 CMR 7.18, the definition of VOC includes specific halogenated organic compounds (HOC), including methylene ch l oride , pe rch lo roethyle n e (tetrachloroethylene), CFC- 11 (tri chl orofluorometh ane), CFC-12 (d ichlorodifl uoromethane) , C FC-22 (ch lorodif l uoromethane), FC-23 (trifl uoromethane), C FC- 114 (dichlorotetraftu oro- ethane), and CFC-115 (ch loropentafl uoroethan e). Therefore, these HOC a l so would be subject to the 1
.0 millimeter vapor pressure requirement for co l d cleaning degreasers. Since the vapor pressure of some of the HOCs exceeds 1.0 millimeter of mercury (e.g., methylene chloride), these HOCs could not be used in cold cleaning degreasers except in those that hold less than 1 liter of solvent or that are exempt as described above. MassOEP believes that i n general there is little use of these toxic HOCs in cold degreasers , but seeks comment on the effect of the inclusion of HOCs in th is proposed amendment. 

### IV
. E MISS IO N RE D UCTIONS MassOEP has used the same methodologl that OTC used for its model rule to estimate VOC emission reductions that would be achieved from implementation of the proposed amendments
. The existing MassOEP regulation for cold 

### solvent degreasing reduces the uncontrolled emissions from this category by half
. Implementation of the proposed amendments will result in a 32 percent emissions reduction from the currently regulated level in Massachusetts
. This amounts to a total emissions reduction of 66 percent from the uncontrolled level6 • 

### MassOEP's statewide VOC emissions inventory for 2002 shows VOC emissions from cold degreasing operations to be 5,712 tons per year (or 22 tons pe r summe r day), which amounts to approxi mately 2 percent of the e nti re 

## voc . em i ssions i nvento ry i n 2002 (or 3 perce nt of total VOC emissions o n a typica l summer day) 7

### 6 emissions from this category by 1,828 tons per year (or 7 tons per summer day) 8 in 2009 compared to the currently regulated l evels (i.e ., a decrease of 32 percent in VOC emissions)
. 

### V. ECONOMIC IMPACTS Low-vapor pressure compliant cold cleaning solvents are readily available on the market at comparable costs and are currently used in many cold cleaning degreasers
. Many OTC states already have adopted regulations similar to those that MassDEP is proposing. Co
. mpliance with this requirement is not expected to pose a significant technical or economic burden on the regulated community. Maryland and Californ ia's South Coast Air Quality Ma nagement District, which have required use of low-volatility solvents in their regulations, determined that a significant segment of the solvent cleaning industry had already switched to solvents that meet the 1
.0 millimeter of mercury vapor pressure requirement limit due to other regulatory requirements such as hazardous waste transport
. Consequently , a s ignificant portion of the costs associated with switching to a low-volatility solvent has already been incurred , or may be imposed by other requirements
. Additionally, many industries that can use aqueous clean ing systems already have converted or likely will convert to such systems because these systems are co;>t effective and benefit health ·and safefy. As a worst-case scenario, the OTC used a cost analysis for implementing the OTC model rule based on California's South Coast Air Quality Management District's cost estimates for its degreasing rule ·(Rule · 1122t According to this analysis, a cost of $1 ,400 per ton of VOC reduced was estimated for compliance with the rule, which corresponds to the capital costs for aqueous cleaning systems for batchloaded cold cleaners
. Replacement of cold solvent degreasers with aqueous cleaning systems in Massachusetts would result in an average cost of$ 2.6 million in 2009 10

. This would translate to a cost of $2
. 16 per Massachusetts resident in 2009. These costs represent a worst-case scenario for compliance with the proposed regulations and are comparable to compliance costs for other regulations for reducing VOCs
. The actual compliance costs are expected to be significantly lower because compliance is expected to be achieved by replacing high-volatility solvents with low-volatility compliant solvents rather than with aqueous cleaning systems. 

### VI. IM PACT ON OTHER MASSDEP PROGRAMS A. Air Toxics Air taxies are a group of chemical air contaminants , defined by EPA, that have been associated with wide-ran ging and s ign ificant adverse health effects, i ncluding cancer and other serious health effects such as reproductive effects or bi rth defects, or adverse environmental effects
. The Clean Air Act requires EPA to promulgate source-specific controls based on Maximum Achievable Control Technologies (MACT) for air taxies
. MassDEP implements certain MACT standards as EPA promulgates them
. In addition, MassDEP controls air taxies through reduction of criteria pollutants and its Taxies Use Reduction Program
. For examp le , many ai r taxies are VOCs , wh ich are regulated as ozone precursors . The proposed amendments to 310 CMR 7.18 will decrease VOC emissions from solvent metal cleaning operations, and because many VOCs also are air taxies, the proposed amendments will decrease the emissions of air taxies
.

8 Th e 2002 emissions were based on employment activity factors for this sector, but the 2009 projections were based on employment growth factors

### 7 B. Toxics Use Reduction 

### Toxics use reducti on is defined as in-plan t or in-process practices that reduce or eliminate the use and emissions of toxic materials into the environment. Implementation of toxics use reduction, when possible , is a MassDEP priority
. The amendments to 310 CMR 7.18 will reduce VOC emissions from the cold cleaning operations and will also result in toxics use reduction because many of the VOCs used in cleaning operations are toxic
. 

### VII. AGRICULTURAL IMPACTS Pursuant to-M.G.L. C. 30A, §18, state agencies must evaluate the impact of proposed programs on agricultural resources within the Commonwealth
. The proposed amendments to contro l VOC emissions from degreasing operations are expected to have positive impacts on agricultural production in Massachusetts
. VOCs are precursors to ground-level ozone, which adversely affects vegetation and some crops. Therefore , a reduction in VOC emiss ions will have a positive impact on ag ri culture. 

### VIII. IMPACT ON MASSACHUSETTS MUNICIPALITIES Pursuant to Executive Order 145 , state agencies must assess the fiscal impact of new regu lations on t he Commonwea lth's municipalities
. MassDEP expects that m u nicipa l facilities will comply with the propose amendments using alternative solvent formulations available at approximately the same price as solvents currently i n use . Therefore, MassDEP expects the proposed amendments to impose minimal or no direct costs, recordkeeping, reporting , or other requ i rements on local governments. 

### IX. MASSACHUSETTS ENVIRONMENTAL POLICY ACT (MEPA) The proposed amendments a re "categorically exempt" from the "Regulations Govern ing the Preparation · · ·· of Environmental I mpact Reports ," 301 CMR 11
.00 , because the proposed amendments w ill result in an overall decrease in emissions.
