### 2008 IMPLEMENTATIONSTATUS OF COMMITTED MEASURES 

### IN 'THE MAG 2007 FIVE PERCENT PLAN FOR PM-10 FOR THE MARICOPA COUNTY NONATTAINMENTAREA The MAG 2007 Five Percent Planfor PM-10for the Maricopa County NonattainmentArea was submitted to the Environmental Protection Agency (EPA) in December2007. Inorder to reduce PM-10, a broad range of commitments to implement measureswere received from the State, Maricopa County, and the twenty-three local governments in the PM-10 nonattainmentarea. The planincludesfiftythreecommitted control measureswhich began implementation in 2008. The Maricopa Association of Governments is tracking the implementation of the measures inthe plan. A tracking form was preparedto assist the implementing entities in reporting the progress made to implement measures for calendaryear 2008. This trackingformwas sentto MAG member agencieson March 12,2009. All completedtrackingforms were received byJuly 22, 2009. MAG has summarized the status of the implementation of the committed measures for calendar year 2008 in Table 1. Table 2 provides additional policies and actions initiated by the Maricopa County Air Quality Department in 2009. Ingeneral, the implementation results for 2008 meet or exceed the commitments made to implement a majority of the measures inthe MAG Five Percent Plan for PM-10. Figure 1 illustrates the PM-10 emission reductions in 2010 for the committed control measures that were quantified for numeric creditto meet the five percent per year target and demonstrate attainment. Figure 2 providesthe PM-10 emission reductions in 2010 for the committed contingency measuresthat were quantified for numericcredit. In some cases, the emission reductions represent the impact of multiple, reinforcing measures. BACKGROUND INFORMATION In accordance with the Clean Air Act, the MAG 2007 Five Percent Plan for PM-10 was submittedto the Environmental ProtectionAgency by December31,2007. The planwas requiredto reduce PM-10 emissions byfive percent per year until the standard is met. In order to attain the standard, the region needs three years of clean data at the monitors (2008, 2009,2010). It is importantto attain the PM-10 standard as quickly as possible or additional years of five percent reductions may need to be added to the plan. The Executive Summary for the MAG 2007 Five Percent Plan for PM-10 is attached. On May23,2007, the MAG Regional Council approved additional itemsfor the Suggested List of Measures to Reduce PM-10. One of the items was that each year, MAG would issue a report on the status of the implementation of the committed measures for this region by the cities, towns, Maricopa County and the State. The report would be made available to the Governor's Office, Legislature, Arizona Department of Environmental Qualityandthe Environmental ProtectionAgency. This reportprovidesthe implementation status of committed measures for calendar year 2008.

### The forms for tracking the implementationof committed measures were developed with input from the implementing entities. MAG conducted three workshops to discuss the tracking of the measures on December 18, 2007; September 23, 2008; and March 31, 2009. The draft formswere also transmitted in October2008 to give advance noticeof the types of information that would be needed by MAG. Monitored exceedances of the 24-hour PM-10 standard have declined since 2006, as shown in Figure 3. There can be no more than three daily exceedances at any PM-10 monitor over a three year period in order for the standard to be met. The measures described inthis tracking report will be important in reducing PM-10 emissions,to enable the regionto meetthe standard by 2010. MAG will continueto monitorthe implementation status of the measures, as well as monitor PM-10 concentrations.IMPLEMENTING ENTITY County

### & E.) In March 2008, Maricopa County adopted Rule 310 and Rule 316 revisions in regard to dust managers.
Maricopa County assigned a supervisorto oversee the vacant lot program.

SB 1552 requiredADEQ to establish a certification program. (A.R.S. 

## 3 49-457.02 A.) This measure was not implemented because ADEQ delayed the certification program indefinitelydue to budgetary constraints. Maricopa County will support ADEQ's efforts (when ADEQ's budgetary constraints are lifted)to develop a program to certify and publicize companies that routinely demonstrate exceptional efforts to reduce airborne dust. As the regulatory authority, Maricopa County will provide verifications of eligible companies as necessaryto implementthis program and as requested by ADEQ.

In March 2008, Maricopa County adopted Rule 310 and Rule 310.01 revisions in regard to tarping. Maricopa County changed the requirements regarding loading haul trucks (i.e., load all haul trucks such that at no time shall the highest point of the bulk material be higher than the sides, front, and back of the cargo container area).IMPLEMENTING ENTITY County

In February2009, the mobile monitoringvan was delivered to Maricopa County. Although Maricopa County conducted nighttime and weekend inspectionsduring 2008, the programwas not fully implemented,as the department was focused on hiring and training additional staff. Nighttime and weekend inspections conducted in 2008 included complaint inspections and targeted inspections of specific industries that operate at night and on weekends. In 2009, Maricopa County initiated a pilot nighttime and weekend inspection program. Following the pilot program, the County initiateda cross-training program for all inspectors to better utilizetheir abilities to deal with all circumstances and source types they may encounter.

9. Increase consistent inspection frequency for permitted sources. Quantified for numeric credit to meet the five percent per year target and demonstrate attainment. In March 2008, Maricopa County adopted Rule280 revisions in regard to inspectionfrequency. Maricopa County hired 32 inspectors, 13 administrative and permit technicians, 6 inspector supervisors, and 4 administrative supervisors for the Dust Control Compliance Program. Maricopa County issued 4,355 permits for dust control sources (Rule 310). Maricopa County conducted 12,303 inspections of dust control permitted sources (Rule 310). Maricopa County hired 5 inspectors for nonmetallic mineral processing facilities (Rule 316). These 5 inspector positions are included in the 32 inspector positions mentioned above. Maricopa County issued 11 7 permits for nonmetallic processing facilities (Rule 316). Maricopa County conducted 443 inspections of nonmetallic mineral processing facilities (Rule 316).

## 5 9-500.27 A.- E. and A.R.S. § 49-457.03) In February 2008, Maricopa County adopted the P-28 Off-RoadVehicle Use in UnincorporatedAreas of Maricopa County Ordinance. This ordinancewas developed to address dust concerns raised by vehicle use and trespass on private and public property. It is intended to complement MaricopaCounty Rule 310.01, which focuses on property owners' responsibility to maintain soil stabilization. Currently, the Maricopa County Ordinance P-28 is undergoing revisions to its penalty structure, which is intended to provide more flexibility in adjudicating cases. Until these revisions are approved, the County is developing informationon frequent complaint areas and access points, enforcement history, ongoing outreach efforts by police departments, Justice Court procedures, and database needs. In addition to responding to complainants' concerns, MCAQD has organized a group of inspectors to gather this type of information and begin making direct contacts in the field. In 2009, MCAQD initiated efforts to develop a partnership with law enforcement agencies, not only to address the inspectors' limited authority on these contacts, but also to provide a consistent enforcement message to the public. 23 local governments have new or existing ordinances to prevent or discourage off-roadvehicle use and restrict access to areas with high off-road vehicle use. ADEQ distributed 3,700 hard copies of "Nature Rules" map to off-road highway vehicle (OHV) dealers and posted materials on the Arizona State Parkswebsite (website received I 1,660visits), ADEQ's website (website received 2,741 visits), and the Arizona Game and Fish Department website.IMPLEMENTING ENTITY County,

20. Provide incentives to retrofit nonroad diesel engines and encourage early re~lacementswith advanced technologies. 2008 IMPLEMENTATION STATUS

In 2007, the Arizona Legislature adopted Senate Bill 1552which included a voluntary diesel equipment retrofit program. (A.R.S. § 49-474.07 A. 

## - D.) According to A.R.S. § 49-474.07 A., a County with a population of more than four hundred thousand persons shall operate and administer a voluntary diesel emissions retrofit program in the county for the purpose of reducing particulate emissions from diesel equipment. The program shall provide for real and quantifiable emissions reductions based on actual emissions reductions by an amount greater than that already required by applicable law, rule, permit or order and computed based on the percentage emissions reductions from the testing of the diesel retrofit equipment prescribed in Subsection C as applied to the rated emissions of the engine and usingthe standard operating hours of the equipment. Maricopa County Air Quality Department (MCAQD) has indicated that A.R.S. § 49-474.07 did not establish a fund to provide incentives to retrofit nonroad engines, but rather established provisions applicable to permitted stationary source diesel powered equipment. Under the provisions of ARS 49-474.07, 

### the permittee may retain one-half of the particulate emissions reductions from retrofit of diesel equipment operated at the permitted site for purposes of receiving a permit modification or a new permit provisionthat allows for extended hours of operation for the permitted equipment. The provisions of ARS § 49-747.07 are undergoing legal review and analysis during the current statewide new source review rulemaking, and if implemented, will require revision of MCAQD's stationary source permitting program and applicable rules. However, this review and analysis has no bearing on the Five Percent Plan or on Committed Measure#20.

SB 1552 requires that new or renewed contracts for street sweeping on city streets must be conducted with PM-10 certified street sweepers. g-500,04A.9. and 49-474.01 A.8.) The 3 local governments that issue street sweeping contracts require that their contractors use PM-10 certified street sweepers. Local governments purchased 8 PM-10 certifiedstreet sweepers with CMAQ funds and 3 PM-10 certified street sweepers with other funds. ADOT's current contract for sweeping State Highways does not require use of PM-10 certified street sweepers (one street sweeper is not PM-10 certified). However, when the ADOT street sweeping contract is renewed, the contract will be revised to require that only PM-10 certified street sweepers are to be used.

ADOT has coordinated public transit services with Pinal County. See the following websites for information regarding this coordination: (1) Arizona RuralTransit Needs Study Final Report

Plan requirements for pavingor stabilizing public dirt roads and alleys were amended by SB 1552. (A.R.S. 39-500.04 A.3. and A.R.S. 549-474.01 A.4.) In March 2008, Maricopa County adopted Rule310.01 revisions in regard to unpaved roads and alleys. Maricopa County and 19 local governments have developed or updated plans to pave or stabilize targeted public dirt roads and alleys. Maricopa County and local governments have implementedthis measure for: Public Dirt Roads By paving 25.02 miles of public dirt roads (15.07 miles more than the commitments) and stabilizing 36.76 miles of public dirt roads (3.09 miles less than the commitments), with a total of 61.78 miles of public dirt roads paved or stabilized (11.98 miles more than the commitments).

### MAG 2007 FIVE PERCENT PLAN FOR PM-10 EXECUTIVE SUMMARY
Withinthe MaricopaCounty nonattainmentarea,the NationalAmbientAirQuality Standard has not yet been attained for PM-10 particulate pollution. The Maricopa Association of Governments was designated by the Governor of Arizona in 1978 and recertified by the Arizona Legislature in 1992 to serve as the Regional Air Quality Planning Agency to develop plansto address air pollution problems. Based upon the 1990 Clean Air Act Amendments, the Maricopa County nonattainment areawas initiallyclassifiedas Moderatefor PM-10 particulate pollution. However, on May 10, 1996, the nonattainment area was reclassifiedto Serious due to failure to attain the particulate standard by December 31, 1 994. The Serious Area reclassification was effectiveon June 10,1996. The Revised MAG 1999 SeriousArea Particulate Planfor PM-10for the MaricopaCounty Nonattainment Area was submitted to the Environmental Protection Agency (EPA) in February 2000. On July 25, 2002, EPA published a notice of final approval for the plan. Collectively,the plan containedapproximatelyseventy-seven committedcontrol measures from the State and local governments. The plan demonstrated attainment of the PM-10 standard by December31,2006. In orderto be in attainment, the region needed three years of clean data at the monitors for 2004,2005, and 2006. However, there were numerous exceedancesof the 24-hour standard in2005 and 2006. OnJune 6,2007, EPA published a final notice with itsfindings that the Maricopa County nonattainmentarea hadfailed to attain the PM-10 standard by the federal deadline of December31,2006. Inaccordance with Section 189 (d) of the Clean Air Act, the Five Percent Plan for PM-10 is due to the Environmental Protection Agency by December 31, 2007. The plan is required to reduce PM-10 emissions by at leastfive percent per year until the standard is attained as measured bythe monitors. The Clean Air Act specifies that the plan must be based upon the most recent emissions inventoryforthe area and also includea modeling demonstration of attainment. Particulateair pollutioncan occurthroughoutthe year. Theformation of PM-10 particulate pollution is dependent upon several factors. Among these factors are stagnant masses, severetemperature inversionsinthe winter, high winds inthe summer, and fine, silty soils characteristic of desert locations. Inthe Maricopa County nonattainment area, particulate matter (PM-10) concentrationsareelevated duringvarious seasonsof the year and under differentweatherconditions. Thevariabilityis duetothediverse compositionof PM-10 and the sources contributing to this diversity. The trend in PM-10 levels for the Maricopa County nonattainment area is presented in Figure ES-1. The 24-hour PM-10 standard is 150 micrograms per cubic meter. In2004,

## in 2006 there were 21 exceedance days of the 24-hour standard. Figure ES-2 indicates the monitorswhere exceedances occurred, The violations of the standard at the Bethune Elementary School, Durango Complex, and West 43d Avenue monitors caused the region to fail to attainthe PM-10 standard by the December31, 2006 attainment date. A rigorous planning effort was conducted to prepare the MAG 2007 Five Percent Planfor PM-10. An extensive Preliminary Draft Comprehensive Listof Measureswas compiled for evaluation. The MAG Analysis of Particulate Control Measure Cost Effectiveness report provided an evaluation of forty-six control measures. For each measure, the following information was prepared: narrative description; suggested implementing entity; estimate ofthe cost of implementation; estimateof the PM-10emission reduction potential;estimate of the cost effectiveness ($/ton of PM-10 reduced); and discussion of implementation issuesand comments. In preparing the information for the analysis, measuresfrom other PM-10 SeriousAreas were reviewed and contacts were established. Relevantdust control literature reviews were performed to obtain data on measured emission reductions. Contacts were established with local agencies and businesses in Maricopa County to determine the cost of labor, equipment, materials, etc. The MAG PM-10 SourceAttribution and Deposition Study was another major study which provided informationfor the evaluationof control measures. The study was designed to identify the sources of emissions contributing to violations of the PM-10 standard at monitors in the nonattainment area during stagnant conditions and characterize the deposition of PM-10 particles emitted by these sources. The MAG consultants for the studywere T&B Systems and Sierra Research. The key questions addressed inthe study were: 1. Where are the specific source areas and/or sources inthe Salt River region that contribute to the particulate matter (PM) loading at the Durango Complex and West 

### 43rdmonitoring sites? 2. To obtain useful results from models such as AERMOD, can the regional particle size distribution be characterized on an area basis (i.e., is there an area of uniformity that can be generalized?) 

### 3. What are the causes of heavy PM loading during the morning hours at the Durango and West 

### 43* monitors? Are the diurnal variations of PM-10 and peaks due to reentrainment of paved road dust, or due to other activities in the surrounding areas that are coincident with traffic peaks? The approach used forthe study involved assessing existing meteorologicaland PM data; selecting monitoring tools; establishing a sampling plan; defining routes for mobile sampling; determining locations of meteorological data collection; selecting locations to investigate dispersion of roadway sources; conducting sampling in two phases;

The monitoring tools for the study included: a particle lidar; mobile monitoring; DustTrak optical PM-10 monitors; DustTrak optical PM-2.5 monitors; an aerodynamic particle size analyzer; MiniVol filter based samplers; a sodar; and a SCAMPER vehicle. The SCAMPER (System for Continuous Aerosol Monitoringof ParticulateEmissionsfrom Roadways) vehicle was used to measure PM-10 from paved roads. From November 15, 2006 through December 14, 2006, extensive measurements were taken in the Salt River area using state-of-the-art technologies. Ingeneral, the study identifieda numberof sources of PM-10 in the Salt Riverarea. They included: trackout; dragout from unpaved or poorly maintained paved roads or parking lots; unpaved shoulders; unpaved roads;open burning; agriculture; and vehicle activityon unpaved parking areas and vacant lots. Preliminary results from the study were used in the evaluation of control measures and the final results were used in the modeling attainment demonstration. Based upon the Maricopa County Air Quality Department 2005 Periodic Emissions Inventory for PM-10for the Maricopa County NonattainmentArea, the primarysources of PM-10 are: Paved Roads (including trackout) 16 percent; Construction (residential) 14 percent; Construction(commercial) 13 percent; Unpaved Roads 10percent; Construction (road) 9 percent; Fuel Combustion and Fires (industrial natural gas and fuel oil, 

### commericial/institutionalnaturalgas andfuel oil, and residential naturalgas, wood andfuel oil) 7 percent; and Windblown Vacant (vacant lots) 7 percent. The sources are depicted in Figure ES-3. The emissions inthe 2005 Periodic Emissions Inventory for PM-10were projectedto 2007, 2008,2009, and 2010. The total controlled emissions of 97,436 tons in the 2007 projected inventorywere usedto calculatethe five percent reductiontarget in emissions (see Figure ES-4). This number was multiplied by five percent to determine the PM-10 emissions reduction target of 4,872 tons per year. To meet this annual target, the 2008 emissions with committed control measures must be at least4,872 tons less thanthe base case2008 emissions; the controlled 2009 emissions must be at least 9,744 tons less than the 2009 basecase emissions; andthe controlled 201 0 emissions must beat least 14,616tons less than the 201 0 base case emissions. In order to reduce PM-10, a broad range of commitments to implement measures were received from the State, Maricopa County, and the twenty-three local governments in the PM-10 nonattainment area. Collectively, the MAG 2007 Five Percent Plan for PM-10 includes fifty-three committed measures. The key committed measures that were quantified as control measures include: Dust Managers/Coordinators at Earthmoving Sites; Increase Rule 310 and 316 Inspections; ExtensiveDustControlTraining; Conduct Nighttime and Weekend Inspections; Strengthen Rule 310 to Promote Continuous Compliance; Pave or Stabilize Dirt Shoulders; Pave or

With the implementation of the committed control measures,the total PM-10 emissions in 201 0 are 82,829 tons (See Figure ES-6),which represents a 19.3 percent reduction in the 201 0 base case emissions. These reductions are necessaryto model attainment of the PM-10 standard at all monitors as expeditiously as practicable, which is 2010. -The total reductions due to the committed control measures also exceed the annual five percent reduction targets in 2008, 2009 and 2010, as indicated in Table ES-1. In accordance with the Clean Air Act, the MAG 2007 Five Percent Plan for PM-10 also contains contingency measures. The contingency measures are committed measures in the adopted planwhich achieve emissions reductions beyond those measures relied upon to model attainment of the standard anddemonstrate progress toward attainment(i.e., five percent reductions, reasonable further progress, and milestones). -The key committed measures in the Five Percent Planthat were quantified as contingency measuresare: Pave or Stabilize Dirt Roads andAlleys; Sweep with PM-10CertifiedStreet Sweepers; ReduceTrackout Onto Paved Roads;Additional Five Million Dollars in 

### FY2007 MAG Federal Fundsfor Paving Dirt Roads and Shoulders; Agricl~ltural Best Management Practices; 15 Mile Per Hour Speed Limits on Dirt Roads; Reduce Offroad Vehicle Use; Certification for Dust Free Developments; and Public Education and Outreach Program. EPA guidance indicates that contingency measures should provide emissions reductions equivalent to one year of reasonable further progress. The reasonablefurther progress requirementsfor Serious PM-10 nonattainment areasare included in Section 189(c)of the Clean Air Act. For the Five Percent Plan, one year of reasonable further progress is equivalent to 

### a reduction in PM-10 err~issions of 4,869 tons. Figure ES-7 shows the impacts of the individual contingency measures in 2010. Collectively, the contingency measures reduce PM-10 ernissions by 5,223 tons in 2008, 7,213 tons in2009, and 9,159 tons in 2010 versus the contingency target of 4,869 tons per year, as shown in Table ES-1. The total 2010 PM-10 emissions with committed control measures and committed contingency measures are 73,670 tons (see Figure ES-8). Together, these measures reduce base case PM-10 emissions by 28.2 percent in 2010. Forconformity analyses,theonroad mobile source emissions budget includesreentrained dust from travel on paved roads; vehicular exhaust, tire wear, and brake wear; travel on unpaved roads; and road construction. In 2010, the PM-10 emissions from these four source categories total 103.3 metric tons per day. This represents the onroad mobile source emissions budget for conformity.
