**SECTION 3 CONTROL MEASURES**  **3.0 Purpose of Section**  This Section identifies and briefl y describes the Massachusetts and federal control measures that will result in reductions of VOCs and/or NOx emissions from Massachusetts sources b y 2008, for purposes o f demonstrating Reasonable Further Progress (RFP) towards attainment (Section 4, Reasonable Further Progress), and b y 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 i n 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 an d/or 2009 milestone y ears 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 wi ll 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 ye ars b y which RFP and attainme nt 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 Ye ar Inventory . (The control measures adopted under the Massachusetts 1 - hour ozone standard SIPs are listed in Appendix 3A, MA 1 -Hour Ozone Standard Control M easures .) Therefore, no credit has been taken in the 2008 RFP anal ys is 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 reduct ions 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 Reasonabl y Available Control Technology (RACT) requirements (See Section 6, RACT ); and 3) Reflect MassDEP’s commitment to adopt additional controls along with other Ozone Transport Commission 3 (OTC) states pursuant to the regional 8 - hour ozone standard attainment planning process. The OTC recognized that some states within the OTC would not b e 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 ye ar. It recommended that OTC states adopt new or additional controls for a number of source categories. 4 The 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 b y 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 significantl y 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 Mas sachusetts 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, Delaw are, 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 desc ribed 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 C

onformity (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 th e 2004 - 2007 phase - in periods. The Tier 2 standards do not appl y 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 NO x and hydrocarbon (HC) emission standards for heavy - duty diesel engines and vehicles starting with the 2004 vehicle model ye ar. The rules also set tighter NOx and HC standards for heav y - dut y gasoline engines and vehicles starting with the 2005 vehicle model y ear. ( Standards vary by vehicle weight and fuel - ty pe.) The rules requires that certain heav y - dut y vehicles (HDVs) be equipped with on - board gasoline vapor recovery s ys tems phased - in over 2004

– 2006 model y ear vehicles. In 2001, EPA published a second phase of heavy - duty motor vehicle emission standards. The rule requires additional, significant reductions of NO x and HC (as well as particulate matter) emissions from heav y - 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. Mas sDEP estimated the emissions from the non road source sector using EPA’s NONROAD Model (version 2005A, Feb. 2006), which has built - inFinal Section 3 - Page 4 of 10

growth factors and control factors for the federal measures. The federal controls will result in significant emission redu ctions 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)), land based non - road diesel engines used in agricultural and construction equipment. These were phased in 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, indus trial, and airport equipment beginning in 2008. Fuel requirements will decrease the sulfur levels in non - road diesel fuel to prevent damage to emission - control sy stems. Current sulfur levels of about 3,000 ppm will be reduced to a maximum of 500 ppm in 200 7. 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 y ear 1997 and newer small (< 25 hp) non - road spark - ignited engines, which are used primaril y i n 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 variet y 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 - veh icles (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 stand ards for recreational marine diesel engines, which are used in ya chts, cruisers, and other ty pes 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 n ew 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 mod el 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 finalize d 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 cr edit 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 ye ar 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 engi nes); 4) revisions to the ZEV regulations with an alternative compliance plan; and 5) and California’s “Not - to Exceed” (NTE) emission standards and test procedures for heav y - dut y diesel engines (HDDE) and vehicles . Emission reductions from the L EV 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 regul ation established a NOx cap and - 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, whic h are described in the narrative that follows, have been taken into account in the 2009 attainment demonstration modeling. **Table CM 1 MassDEP Schedule for Control Measure Regulations**  **Regulation Date of**

**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 sign ificantl y to ozone nonattainment in downwind states and that NOx and sulfur dioxide (SO 2 ) emissions from 23 states and the District of Columbia contribute significantl y to PM 2.5 nonattainment in downwind states. CAIR set an ozone season NOx cap for each st ate contributing to ozone nonattainment and annual NOx and SO 2 caps for each state contributing to PM 2.5 nonattainment. EPA concluded that Massachusetts significantl y contributes to ozone nonattainment in Connecticut and Rhode Island, but does not contrib ute 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 SI P revision th at 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 wi th the 2009 ozone season, Mass CAIR will replace the existing NO x Budget Program, which has capped ozone - season NO x emissions from EGUs and other large boilers since 2003 at a less stringent cap. Mass CAIR covers all sources subject to the existing NOx Bud get 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 Secti on 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 oz one 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 b y April 1, 2009. It anticipates that its asphalt paving regulation amendments will be effective by May 1, 2009. These emissions benefits are taken into account for purposes of the attainment demonstration modeling, as discussed in Sectio n 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 d id 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. T he 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. Bec ause 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 sea lant 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. Howev er, with the exception of aerosol adhesives, the definitions of these products generall y 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 o f these materials and developed a 2006 OTC model rule, based on a reasonabl y available control technology determination prepared b y 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 liste d 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 mi lestone y ears.Final Section 3 - Page 9 of 10

As noted in that document, the 2009 benefit is the incremental reduction from the measure (the difference betw een the 2009 projected emissions before the control and 2009 post - control emissions). The calculations on which Appendix 5K are based are av ailable 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 calc ulations and noted in Appendix 3B.
