SECTION 3 CONTROL MEASURES

3.0 Purpose of Section

This Section identifies and briefly describes the Massachusetts and federal control measures that 

will result in reductions of VOCs and/or NOx emissions from Massachusetts sources by 2008, for 

purposes of demonstrating Reasonable Further Progress (RFP) towards attainment (Section 4, 

Reasonable Further Progress), and by 2009, for purposes of demonstrating attainment of the ozone 

standard (Section 5, Attainment Demonstration). MassDEP has already promulgated regulations 

related to some of the measures for which it is taking credit in its RFP and attainment 

demonstrations. For other measures, it is committing to adopt regulations and submit them to EPA 

as SIP revisions, according to the schedule included in this Section. 

The Massachusetts and federal control measures described in the narrative below are listed in Table 

CM 2, with the date of their effectiveness noted. The estimated reductions in VOC and/or NOx that 

the measures will achieve in the 2008 and/or 2009 milestone years in EMA and WMA are shown in 

Table CM 3. 

3.1 Massachusetts Post -2002 Emissions Reductions

EMA and WMA are allowed to take credit for RFP and attainment demonstration purposes for 

emissions reductions of VOCs and/or NOx that will be achieved after the 2002 base year. 

Reductions may be from state or federal control measures already “on-the-books/on-the-way,”1

provided that the reductions from such measures will take place after 2002, but before the years by 

which RFP and attainment must be demonstrated. 

3.1.1 Massachusetts 1-Hour Ozone Standard SIP Measures

Generally, the reductions from control measures that were adopted as part of the 1-hour ozone 

standard attainment SIPs for EMA and WMA are already reflected in the MA 2002 Base Year 

Inventory. (The control measures adopted under the Massachusetts 1-hour ozone standard SIPs are 

listed in Appendix 3A, MA 1-Hour Ozone Standard Control Measures.) Therefore, no credit has 

been taken in the 2008 RFP analysis and 2009 attainment demonstration for 1-hour measures, with 

two exceptions: the Massachusetts Low Emission Vehicle (LEV) program and the Massachusetts 

NOx Budget Program. The LEV program (discussed in subsection 3.5.1) was adopted in 1995, but 

will continue to generate emission reductions in 2008 and 2009. The NOx Budget Program 

(discussed in subsection 3.5.2) was adopted in 1999, for implementation in the 2003-2008 ozone 

seasons. Therefore, the post-2002 reductions from these two “on-the-way” measures adopted in 1-

hour ozone standard SIPs are taken into account in the 2008 RFP and 2009 attainment 

demonstrations. 

 

1 The term “on-the-books/on-the-way” was used during the Ozone Transport Commission (OTC) regional 

attainment process to describe control measures that states already expected to be in place by the 2009 8-hour 

attainment year; they are referred to in this Section as “on-the-way” measures. They are distinguished from 

the new control measures that the OTC recommended as an outcome of the regional 8-hour ozone standard 

attainment planning process. 
Final Section 3 - Page 2 of 10

3.1.2 New Massachusetts Control Measures

MassDEP is adopting new control measures that were not part of its 1-hour ozone standard SIP 

commitments. In addition to helping Massachusetts demonstrate attainment of the ozone standard in 

2009, the new measures will: 

1) Address Massachusetts’contribution to ozone non-attainment in other states;2

2) Meet Reasonably Available Control Technology (RACT) requirements (See Section 6, 

RACT); and 

3) Reflect MassDEP’s commitment to adopt additional controls along with other Ozone 

Transport Commission3(OTC) states pursuant to the regional 8-hour ozone standard 

attainment planning process. 

The OTC recognized that some states within the OTC would not be able to attain the 8-hour ozone 

standard without more reductions than will be achieved under EPA’s Clean Air Interstate Rule 

(CAIR) and other state and federal control measures expected to be in place by the 2009 attainment 

year. It recommended that OTC states adopt new or additional controls for a number of source 

categories.4The OTC went through a similar process under the 1-hour ozone standard and, in 2001, 

recommended new controls to help member states attain the 1-hour ozone standard. As part of its 8-

hour ozone attainment strategy, MassDEP is adopting a number of 2001 and 2006 OTC 

recommended control measures, as discussed below (Sections 3.6.2 – 3.6.4).

3.1.3 Emissions from States Upwind of Massachusetts

Air quality in Massachusetts is significantly impacted by the transport of emissions from upwind 

states. However, nonattainment areas do not receive credit towards RFP for the reductions achieved 

in upwind states, even though such measures are likely to significantly improve downwind air 

quality. For attainment purposes, the modeling on which the attainment demonstration for EMA and 

WMA are based takes into account substantial emission reductions that will take place in upwind 

states by 2009, as discussed in Section 5, Attainment Demonstration. 

 

2 MassDEP is simultaneously submitting to EPA the final Massachusetts State Implementation Plan Revision 

to Meet Clean Air Act Section 110(a)(2)(D)(i) Interstate Air Pollution Transport Requirements (Transport 

SIP), which demonstrates that Massachusetts sources are not contributing to nonattainment of the NAAQS 

for ozone or fine particles (PM 2.5) in areas that are located downwind of Massachusetts. 

3

Sections 184(a) and 176A of the CAA established the Northeast Ozone Transport Region (OTR) and the 

Ozone Transport Commission (OTC). The OTR is comprised of the District of Columbia, a portion of 

Northern Virginia, and the states of Maine, 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 

to help the OTR meet the NAAQS for ozone. 

4 The OTC regional 8-hour ozone planning process is discussed in greater detail in Section 5, Attainment 

Demonstration and Section 7, Reasonably Available Control Measures. 
Final Section 3 - Page 3 of 10

3.2 Federal “On-the Way” On-Road Mobile Source Measures 

EPA has promulgated federal regulations that will result in emission reductions from on-road vehicles 

in all states in future years. These federal on-road control measures, which are briefly described below 

(subsections 3.2.1 and 3.2.2), will result in significant emission reductions from mobile sources in 

EMA and WMA in 2008 and 2009. The 2008 and 2009 mobile source emissions estimates for EMA 

and WMA are based on EPA’s MOBILE 6.2 model, which incorporates the benefits of all federal 

regulations that apply to the on-road mobile source sector. (Technical inputs to the Mobile 6.2 model 

runs are more fully described in Section 4, Reasonable Further Progress (for 2008) and Section 9, 

Transportation Conformity (for 2009). More information concerning the federal measures discussed 

below is available at EPA’s website: http://www.epa.gov/otaq/hwy.htm.

3.2.1 Tier 2/Fuel Standards

In 2003, EPA adopted final rules requiring stricter tailpipe emission standards (Tier 2) for all new 

passenger vehicles, including cars, sport utility vehicles, minivans, vans, and pick-up trucks. At the 

same time that it promulgated the Tier 2 standards, EPA also promulgated a regulation lowering the 

sulfur content in gasoline over the 2004-2007 phase-in periods. The Tier 2 standards do not apply in 

Massachusetts, which has adopted the stricter California Low Emission Vehicle Program tailpipe 

standards discussed in Subsection 3.6.1 below. However, the low sulfur fuel requirements will 

reduce post-2002 motor vehicle emissions in EMA and WMA and are reflected in the MOBILE 6.2 

model runs for 2008 and 2009.

3.2.2 Heavy-Duty Engine and Fuel Standards

In 2000, EPA published rules setting the first phase of more stringent NOx and hydrocarbon (HC) 

emission standards for heavy-duty diesel engines and vehicles starting with the 2004 vehicle model 

year. The rules also set tighter NOx and HC standards for heavy-duty gasoline engines and vehicles 

starting with the 2005 vehicle model year. (Standards vary by vehicle weight and fuel-type.) The 

rules requires that certain heavy-duty vehicles (HDVs) be equipped with on-board gasoline vapor 

recovery systems phased-in over 2004 – 2006 model year vehicles.

In 2001, EPA published a second phase of heavy-duty motor vehicle emission standards. The rule 

requires additional, significant reductions of NOx and HC (as well as particulate matter) emissions 

from heavy-duty engines and vehicles, beginning with vehicle model year 2007. It also requires 

lowering the sulfur content of diesel fuel to 15 parts per million (ppm) from previous levels of 500 

ppm, beginning in 2006. 

3.3 Federal “On-the-Way” Non-Road Mobile Source Measures

EPA has adopted national regulations that impose emission and fuel standards on new non-road 

engines. The non-road measures, which are discussed below (subsections 3.3.1 – 3.3.4), apply to 

engines such as those used in construction equipment, lawn and garden equipment, recreational 

vehicles, marine vessels, locomotives and aircraft. MassDEP estimated the emissions from the nonroad source sector using EPA’s NONROAD Model (version 2005A, Feb. 2006), which has built-in 
Final Section 3 - Page 4 of 10

growth factors and control factors for the federal measures. The federal controls will result in 

significant emission reductions from this source sector in EMA and WMA in the 2008 and 2009 

milestone years. Additional information concerning these non-road measures below can be found at 

EPA’s website at http://www.epa.gov/nonroad. 

3.3.1 Non-Road Diesel Engine and Fuel Standards

EPA regulations establish four tiers of emission standards for new non-road diesel engines. Tier 1 

emission standards were issued in 1994 for most large (greater than 50 horsepower (hp)), landbased non-road diesel engines used in agricultural and construction equipment. These were phasedin between 1996 and 2000. In 1998, EPA promulgated Tier 1 standards for smaller (< 50 hp) diesel 

engines, which were phased-in between 1999 and 2000. At that time, EPA also issued more 

stringent Tier 2 emission standards for all non-road diesel engine sizes, with a 2001- 2006 phase-in, 

and Tier 3 standards for new diesel engines between 50 and 750 hp, with a 2006 - 2008 phase-in. 

In 2004, EPA promulgated regulations that integrate new non-road diesel engine emission standards 

(Tier 4 standards) with requirements to decrease the allowable levels of sulfur in non-road diesel 

fuel. The regulations set emission standards for engines used in most construction, agricultural, 

industrial, and airport equipment beginning in 2008. Fuel requirements will decrease the sulfur 

levels in non-road diesel fuel to prevent damage to emission-control systems. Current sulfur levels 

of about 3,000 ppm will be reduced to a maximum of 500 ppm in 2007. The second phase will 

reduce sulfur levels in non-road diesel fuel to 15 ppm in 2010, except for locomotive and marine 

diesel fuel, which will be reduced to 15 ppm in 2012. 

3.3.2 Non-Road Spark Ignition (Gasoline) Engine and Fuel Standards 

In 1995, EPA issued Phase 1 standards for model year 1997 and newer small (< 25 hp) non-road 

spark-ignited engines, which are used primarily in lawn and garden equipment. In 1999, EPA issued 

more stringent Phase 2 emission standards for small non-handheld engines (e.g., lawn mowers, 

generator sets, air compressors) and, in 2000, for small handheld engines (e.g., leaf blowers, chain 

saws, augers). Phase 2 standards were phased-in from 2001 to 2007 for non-handheld engines and 

from 2002 to 2007 for handheld engines. 

In 1996, EPA finalized emission standards for new gasoline spark-ignition marine engines to be 

phased-in between 1998 and 2000. These engines are used for outboard engines, personal 

watercraft, and jet boats. 

In 2002, EPA promulgated new engine emission standards for large spark-ignition engines rated 

over 19 kilowatts (kW), or >25 hp. These are used in a variety of commercial and industrial 

settings, including forklifts, electric generators, airport baggage transport vehicles, farming and 

construction. The standards were implemented in two tiers - Tier 1 started in 2004 and Tier 2 in 

2007. EPA’s 2002 rulemaking also include exhaust emission standards for engines in recreational 

vehicles including snowmobiles, off-highway motorcycles, and all-terrain-vehicles (ATVs). These 

standards are phased-in in 2006 and 2007, except for snowmobiles, which have until 2009 to be 

fully phased-in. Plastic fuel tanks and rubber hoses available on recreational vehicles will also be 

subject to permeation standards effective in 2008.
Final Section 3 - Page 5 of 10

3.3.3 Marine Diesel Engines 

In 1999, EPA promulgated regulations setting emission standards for certain classes of new 

commercial marine diesel engines starting in 2004 and for other classes in 2007. In 2002, EPA 

promulgated new emission standards for recreational marine diesel engines, which are used in 

yachts, cruisers, and other types of pleasure craft. The standards are phased-in, beginning in 2006, 

depending on the size of the engine. By 2009, emission standards will be in effect for all new 

recreational, marine diesel engines. 

3.3.4 New Federal Portable Fuel Containers (PFCs) Regulation

In 2001, the OTC developed a model rule for reducing emissions for PFCs (gas cans) based on the 

California PFC regulation. The OTC developed a revised 2006 model rule for this category, based 

on revisions to the California regulation. MassDEP did not adopt a PFC regulation for 1-hour ozone 

standard purposes, but intended to do so as part of its 8-hour attainment strategy. However, in 

February 2007, EPA finalized a national regulation to reduce hazardous air pollutant emissions 

from mobile sources, which includes standards to reduce PFC emissions from evaporation, 

permeation, and spillage. The standards apply to containers manufactured on or after January 1, 

2009. Emission reductions will be realized incrementally as consumers replace older PFCs with 

new ones. Because EPA’s rule has been finalized with a 2009 effective date and will achieve 

reductions equivalent to the OTC model rule, MassDEP no longer intends to adopt a state rule for 

this category. 

3.4 Massachusetts “On-the-Way” Control Measures

There are two control measures adopted in Massachusetts 1-hour ozone standard SIPS that 

continue to generate post-2002 emission reductions for which EMA and WMA can take credit in 

2008 and/or 2009 - the Low-Emission Vehicle Program and the NOx Budget Program. 

3.4.1 Low Emission Vehicle Program (LEV) 

In 1990, Massachusetts adopted the California Low Emission Vehicle (LEV) standards for 1995 

and later model year vehicles sold and registered in Massachusetts. The LEV standards now apply

to all vehicles weighing up to 14,000 pounds, which must be certified to California emissions 

standards. Since the LEV Program was adopted in 1990, the Department has amended the LEV 

regulation to adopt: 1) the fleet-wide emission average for non-methane organic gases (NMOG); 2) 

the next generation of California emission standards known as “LEV II”; 3) the LEV I & II 

emission standards for medium-duty vehicles (including diesel vehicles and engines); 4) revisions 

to the ZEV regulations with an alternative compliance plan; and 5) and California’s “Not-toExceed” (NTE) emission standards and test procedures for heavy-duty diesel engines (HDDE) and 

vehicles.

Emission reductions from the LEV program are estimated using the MOBILE 6.2 model. MassDEP 

used EPA-approved inputs to the model to incorporate benefits from the LEV program in 2008 and 

2009. Due to fleet turnover and the declining fleet wide average requirement under the LEV 

program regulations, the program will generate emission reductions in these milestone years. 
Final Section 3 - Page 6 of 10

3.4.2 NOx Budget Program

In 1999, MassDEP promulgated 310 CMR 7.28, NOx Allowance Trading Program, (the NOx 

Budget Program) and submitted it to EPA as a SIP revision. The regulation established a NOx capand-trade program consistent with EPA’s NOx “SIP Call”, which required NOx emission reductions 

from power plants in 22 Eastern states and the District of Columbia. (63 FR 57,356, 1998). The 

program set a statewide annual, ozone season cap of 12,860 tons of NOx emissions from electric 

generating units (EGUs, as defined in the regulation) and large industrial boilers in Massachusetts 

for the 2003 through 2008 ozone seasons. The NOx emissions reductions achieved under this 

program are taken into account in 2008 for RFP purposes. 

3.5 Massachusetts New or Revised Regulations 

MassDEP is adopting new regulations, or revising existing regulations, in 2007 and 2008 that will 

reduce emissions of NOx and or VOCs in 2009 and beyond. For some of these measures, the new or 

revised regulations have been promulgated prior to this SIP submission. For others, MassDEP is 

committing to promulgate regulations according to the schedule below. Emission reductions from 

these new measures, which are described in the narrative that follows, have been taken into account 

in the 2009 attainment demonstration modeling.

3.5.1 Clean Air Interstate Rule (CAIR)

In EPA’s Clean Air Interstate Rule (CAIR), promulgated in May 2005, EPA concluded that NOx 

emissions in 25 states and the District of Columbia contribute significantly to ozone nonattainment 

in downwind states and that NOx and sulfur dioxide (SO2) emissions from 23 states and the District 

of Columbia contribute significantly to PM2.5 nonattainment in downwind states. CAIR set an ozone 

season NOx cap for each state contributing to ozone nonattainment and annual NOx and SO2 caps

for each state contributing to PM2.5 nonattainment. EPA concluded that Massachusetts significantly 

contributes to ozone nonattainment in Connecticut and Rhode Island, but does not contribute to 

downwind PM2.5 nonattainment. Therefore, Massachusetts is subject to the CAIR seasonal 

program, which caps NOx emissions starting with the 2009 ozone season. 

To meet CAIR requirements, on March 30, 2007, MassDEP submitted to EPA a SIP revision that 

included new regulation 310 CMR 7.32, Massachusetts Clean Air Interstate Rule (Mass CAIR), and 

amendments to existing regulation 310 CMR 7.28, NOx Allowance Trading Program. EPA 

approved the MassCAIR SIP on December 3, 2007 (72 FR 67854). 

Beginning with the 2009 ozone season, Mass CAIR will replace the existing NOx Budget Program, 

which has capped ozone-season NOx emissions from EGUs and other large boilers since 2003 at a 

less stringent cap. Mass CAIR covers all sources subject to the existing NOx Budget Program and 

lowers the total ozone season NOx budget from 12,861 tons to 7,914 tons in 2009 and to 6,656 tons 

in 2015 and thereafter.

By electing to make all Massachusetts sources that were part of the NOx Budget Program subject to 

Mass CAIR, MassDEP is limiting emissions from 15 NOx sources that do not meet EPA’s CAIR 

applicability criteria and were not required to be included in Mass CAIR. 

3.6.2 RACT Measures 

RACT requirements for 8-hour ozone nonattainment areas are discussed in detail in Section 6, 

Reasonably Available Control Technology (RACT). As noted in that Section, MassDEP has 

determined that its existing solvent metal degreasing, gasoline dispensing vapor recovery, and 

asphalt paving regulations do not constitute RACT under the 8-hour ozone standard. MassDEP 

intends to revise its regulations for these categories to require tighter VOC controls. The proposed 

new regulations for these categories are described in Section 6. 

MassDEP expects that the solvent degreasing regulation revisions will be effective by April 1, 

2009. It anticipates that its asphalt paving regulation amendments will be effective by May1, 2009. 

These emissions benefits are taken into account for purposes of the attainment demonstration 

modeling, as discussed in Section 5, Attainment Demonstration. MassDep has not estimated the 

reductions that will take place as a result of the gasoline dispensing vapor recovery rule revisions 

for RFP or attainment demonstration purposes. It expects that the reductions will be minimal 

because of the small number of facilities that have vapor balance systems on underground tanks. 

3.6.3 Consumer Products and Architectural & Industrial Maintenance (AIM) Coatings
Final Section 3 - Page 8 of 10

MassDEP has adopted amendments to existing regulation 310 CMR 7.25, Best Available Controls 

for Consumer and Commercial Products, to further reduce emissions of VOCs from architectural 

and maintenance (AIM) coatings and consumer products. The regulations were promulgated on 

October 19, 2007. 

Most states in the OTR adopted new regulations for these categories based on 2001 OTC Model 

Rules; however, Massachusetts did not. During the 2006 ozone strategies review process, the OTC 

reviewed the potential for additional VOC reductions from consumer products and AIM coatings. 

The OTC did not recommend further reductions from the AIM category. For consumer products it 

recommended additional VOC controls (based on 2005 revisions to the California consumer 

products regulation) and developed a 2006 OTC model rule for consumer products. 

The Massachusetts 2007 amendments to 310 CMR 7.25 incorporate the 2001 OTC model rule VOC 

content controls for consumer products and AIM coatings. For consumer products, the amendments 

incorporate the additional restrictions in the 2006 OTC model rule. Because the reductions are 

effective as of January 2009, they are not taken into account for RFP purposes, but are taken into 

account for the 2009 attainment demonstration modeling.

3.6.4 Adhesives and Sealants

Adhesives, sealants, adhesive primer, and sealant primer are used in product manufacturing, 

packaging, construction, and installation of metal, wood, rubber, plastic, ceramics, or fiberglass 

materials. The 2001 OTC model rule for consumer products contains VOC limits for adhesives and 

sealants. However, with the exception of aerosol adhesives, the definitions of these products 

generally exempt products sold in larger containers. 

The OTC identified this as a category where additional reductions could be achieved in the 

industrial and commercial use of these materials and developed a 2006 OTC model rule, based on a 

reasonably available control technology determination prepared by the California Air Resources 

Board in 1998. The OTC model rule addresses emissions from these materials by providing options

for VOC content that meets specified limits or for use of add-on controls. It also imposes labeling 

and storage requirements for these materials. MassDEP intends to adopt a new regulation based on 

the OTC model rule with an effective date of April 1, 2009. No reductions from this measure are 

taken into account for RFP purposes, but have been included in the 2009 attainment demonstration 

modeling.

3.6.5 Effective Date of Control Measures and Estimated Reductions 

The control measures discussed above are listed in Table CM 2 with an indication of whether 

reductions from the measures have been included for RFP purposes and/or for attainment 

demonstration purposes. Table CM 3 reflects the estimated reductions that MassDEP expects the 

measures to achieve in the milestone years.

used to set the Transportation Conformity Budgets discussed in Section 9, Transportation Conformity. 

6 EPA’s NONROAD model incorporates growth factors and emission control factors for federal non-road controls. 

7 Reductions from the PFC, consumer products, adhesives and asphalt paving categories are based on the OTC regional 

ozone attainment planning process analysis, discussed in detail in Appendix 5K, Identification and Evaluation of 

Candidate Control Measures: Final Technical Support Document, MACTEC, February 28, 2007. As noted in that 

document, the 2009 benefit is the incremental reduction from the measure (the difference between the 2009 projected 

emissions before the control and 2009 post-control emissions). The calculations on which Appendix 5K are based are 

available on the Ozone Transport Commission website: http://www.otcair.org/document.asp?fview=Report#, as 

Appendix D to the Control Measures 2007 - Technical Support Document. Reduction estimates for the AIM and solvent 

categories are based on MassDEP’s calculations and noted in Appendix 3B.
