Status Report on Air Quality Analysis for the Mira Loma Area
Staff gave a presentation on the Mira Loma Study – an analysis of the impact of diesel particulate emissions from warehouse/distribution center operations in the area of Mira Loma and the adjacent areas of Ontario and Fontana. The purpose of this study is to estimate risks associated with current operations and presumed build-out of open space by 2010. To provide good background information, staff used the MATES-II analysis as the baseline for this study. Environmental Compliance Solutions (ECS) was contracted to conduct surveys, and a Kaiser project, on which an extensive EIR had been conducted, was used to establish emission profiles for this study. For modeling, the study used the following applications: MATES-II modeling grid of 2 km x 2 km; use of Urban Airshed Model; an annual simulation using April 1, 1998 through March 31, 1999 meteorology; and a per-grid average estimation of diesel particulate risk. For analysis purposes, the Mira Loma area was divided into 12 gridded areas.

In summary, results of the study indicate the following. Current (2002) warehouse/distribution center operations increase MATES-II Mira Loma baseline cancer risk by an average of 18 in one million; maximum increase in one grid area is up to 49 in one million. In the year 2010, average cancer risk increase without the build-out is 11 in one million due to fleet turnover; maximum increase in one grid area is up to 30 in one million. With the full build-out scenario, Mira Loma average cancer risk is expected to increase by 15 in one million; maximum increase in one grid area is up to 34. The study also shows that cancer risk is found lower in residential areas due to prevailing wind direction. However, staff caveated the current analysis as preliminary and highlighted technical limitations in the study, such as the grid size and modeling technique used. Staff further suggested that receptor oriented modeling may be warranted to detect more localized exposure levels.
 

3) 

Report on CARB’s Clean Air Plan
Staff provided an overview of CARB’s proposed Clean Air Plan (CAP). The CAP is developed for the following purposes: improve air quality and public health; provide a plan for a 20-year period; reduce ozone, PM, CO, and air toxics; promote integrated approach between state, local and federal agencies; reduce state’s contribution to global climate change; and address environmental justice issues. The CAP is not legally binding and does not commit CARB to adopt proposed measures – commitments will be reflected in future SIPs. Four categories of strategies are proposed: regulatory; technical evaluation/assessment; voluntary and educational; and incentive. Key components of the strategies are: 110+ control strategies; requirements for cleaner vehicles, equipment, fuels and products; tighter control on toxics; local strategy recommendations; efficiency enhancement opportunities; and education type of measures. Strategies for mobile source emission reductions cover the following areas: light- and medium-duty vehicles; on-road heavy-duty gas and diesel engine and vehicles; off-road engines; off-road motor cycles/all-terrain vehicles; commercial marine vessels and ports; aircraft and airports; locomotives and railyards; and conventional and alternative fuels. Strategies for stationary and areawide sources emission reductions cover the following areas: consumer products; pesticides; vapor recovery; fugitive emissions; solvents and coatings; combustion, heat and power equipments; residential and open burning; and miscellaneous sources. The following strategies are also proposed: children’s environmental health strategies; incentive strategies; public action strategies; and transportation and land use strategies.

The statewide emission reductions by 2010 are estimated as: VOC – 250 tons/day; NOx – 250 tons/day; PM10 – 50 tons/day; and some toxic reductions. CARB is obligated to achieve 100 tons/day of VOC reduction in the South Coast Air Basin by 2010. Technical evaluation of proposed measures will quantify any potential shortfalls. Annual costs associated with the CAP are estimated to be approximately $2.3 billion in 2010 which amounts to 0.2% of the state’s economic output. 55% of the costs are expected to be associated with stationary and areawide sources strategies, and 45% with mobile sources strategies. Cost estimates include compliance costs with state and federal requirements and local adoptions and implementations. Cost effectiveness is expected to be: $900-$25,000 per ton of VOC; and $5,000-$23,000 per ton of NOx. It is also estimated that CAP will result in 8,000 fewer jobs created, which amounts to 0.06% of the current employment force. Previous cost analyses indicate $3 benefits for every $1 invested.

Status Report on CEQA Handbook
At the Committee’s request, staff conducted a study on Localized Significance Thresholds (LSTs) effects on past projects that previously qualified for a Negative Declaration (ND). The goal of the study was to conduct an initial assessment of resource impacts through the following tasks: 1) compilation and review of emissions from past NDs for projects in various Source Receptor Areas (SRAs); 2) comparison of emissions to proposed LSTs; 3) identification of NDs that exceed LSTs; and 4) identification of additional costs associated with preparation of an Environmental Impact Report (EIR) instead of an ND.

Staff provided a brief summary on the study and review results. Only the attainment pollutants NO2 and CO were evaluated at this time. The results of this study were based on the following assumptions: year 2000 ambient concentrations were used to derive attainment LSTs; 1-acre project size was assumed; and sensitive receptors at distances of 50- and 100-meters were evaluated. A total of 110 NDs were reviewed. Of this total, only 42 NDs from the 4 counties of Los Angeles, Orange, Riverside, and San Bernardino had calculated emissions and were evaluated further. Out of the 42 NDs, 8 were found to be significant under the existing Regional Significance Thresholds (RSTs) and excluded from further analysis. Out of the remaining 34 NDs, only 4 projects in L.A. County exceed LSTs at both 50 meters and 100 meters, and only during construction. Staff identified additional mitigation measures and costs and concluded that using LSTs may result in the preparation of approximately 12 percent more EIRs. Costs that will be incurred for the preparation of the additional EIRs, per project, are estimated to be: 1) Consultant’s preparation cost - between $15,000 (minimum) and $24,000 (maximum); and 2) the lead agencies’ preparation costs - between $3,933 (minimum) and $6,547 (maximum). In conclusion, the study shows that, typically, only the construction portion of the land use projects would be affected by using the LSTs. The operation portion of most land use projects would not use the LSTs because they typically do not involve a localized source of emissions such as heavy-duty diesel trucks. The LST approach also has the potential to increase resources costs. Staff concluded by stating that the number of additional EIRs required will be influenced by the following factors: project-specific information; actual number of emissions sources at the site; revised methodologies in the CEQA Handbook; future improvements in air quality; and modeling assumptions. Staff also recommended that once the LSTs are finalized, similar analysis be performed again to refine the findings.

SUMMARY OF MEETING HELD ON APRIL 26, 2002

Attendance
The meeting started at 9:10 a.m. Present: Committee Chair Roy Wilson, Vice Chair Jon Mikels, and Committee Member Jane Carney.. Absent: Committee Members Norma Glover, Ron Loveridge and Jim Silva. The attachment is an attendance roster.

INFORMATION ITEMS

1) 

Update on Coachella Valley SIP
Staff gave a status report on the 2002 Coachella Valley PM10 State Implementation Plan (2002 CVSIP) that is in preparation. As was noted at the January Mobile Source Committee meeting, the 1999 through 2001 PM10 levels did not attain the PM10 standard. Staff also noted that the 2002 CVSIP will include a request to extend the 2001 PM10 attainment deadline for Coachella Valley and that request must be accompanied by a new attainment demonstration, control strategy, and a Most Stringent Measures (MSM) analysis. The 2002 CVSIP must be submitted before July 2002 to forestall any potential for an EPA notice of failure to attain. Coachella Valley stakeholders are once again responding proactively to this situation. After being briefed on the situation in late January, the Coachella Valley Association of Governments (CVAG) established an Ad Hoc Air Quality Task Force (CV Task Force) on February 14th to assist AQMD staff in the timely development and implementation of the 2002 CVSIP. In particular, the CV Task Force will help identify the appropriate MSM upgrades to existing local and AQMD dust regulations, survey and recommend enhancements to the local enforcement procedures, identify funding and MOU mechanisms, and help implement the 2002 CVSIP. The draft outline of the 2002 CVSIP, including the updated emissions inventory, MSM analysis, control measure that came from the CV Task Force process, attainment demonstration, Natural Events Action Plan status and update, and request for extension of the PM10 deadline, was presented. Lastly, the CVSIP schedule was described, culminating in the proposed special June Board Hearing.
 

2) 

Update on CARB Proposed Particulate Matter Standards
Staff presented a summary of the CARB recommended new particulate standards. At the request of the state Air Quality Advisory Committee, CARB staff proposed PM2.5 Ambient Air Quality Standard at 25 micrograms per cubic meter averaged over 24 hours. Staff also presented a comparison of the proposed California standard to the federal particulate matter standards, and to the 24-hour levels of PM2.5 in the SOCAB measured in 2001. The CARB Board is scheduled to consider approval of the standards at its June 2002 meeting.
 

3) 

CARB Transit Bus Study
A summary of the transit bus study results described in a CARB press release was presented by staff. CARB tested two transit buses from the LA MTA fleet - one diesel-fueled and one CNG-fueled. The diesel bus was tested using ARCO ECD-1 low sulfur diesel with either a new oxidation catalyst or a new particulate trap, and the CNG bus had no exhaust aftertreatment. Both the trap equipped diesel and the CNG bus showed low emissions of particulates. The CNG-fueled bus showed lower NOx emissions than the diesel-fueled bus. The bus equipped with the particulate trap showed lower emissions of volatile organic compounds and mutagenicity (Ames bacterial assay of particulate extracts) than the CNG bus. However, there are a number of significant deficiencies related to the preliminary testing to be resolved by future studies. The portion of NOx emitted as NO2 was higher in the trap equipped diesel-fueled bus. Staff noted that these are preliminary results from an ongoing study, and recommended that the study should be completed and the data analyzed before conclusions are drawn. CARB is conducting additional tests with CNG-fueled buses equipped with oxidation catalysts. Preliminary test results from CARB showed that the oxidation catalyst substantially reduced emissions of hydrocarbons and carbon monoxide from the CNG bus.

Committee Member Carney inquired as to the status and schedule of the District's study of transit bus emissions, and asked staff to ensure the timely completion of the analyses. Staff responded that the schedule is to have a draft report of the mutagenicity tests, being conducted by U.C. Davis, by the beginning of July, and to have a draft of the analyses of particulate organics, which include PAH and nitro-PAH compounds, next month.
 

4) 

Proposed Amendments to Rule 1193
Staff provided an overview of the proposed amendment to Rule 1193 – Clean On-Road Residential and Commercial Refuse Collection Vehicles. The proposed amendment would remove the sunset date of July 1, 2002 for the purchase of dual-fuel curbside collection vehicles. Staff indicated that there were prior concerns regarding the greater use of diesel fuel in a refuse "stop-and-go" cycle and the potential for the dual-fuel engine to revert to straight diesel usage. Based on current CARB certifications of dual-fuel engines, staff believes that the concerns have been addressed. Public comments were received that dual-fuel engines would emit more emissions than dedicated alternative-fueled engines and that more in-use emissions data would be needed before removing the sunset date. Staff indicated that with CARB’s certification that the engines would operate primarily with the alternative fuel in a refuse-type cycle, and that certified emission levels are intended to reflect in-use emissions profiles. In addition, any alteration of the dual-fuel engine to operate on diesel fuel would be considered tampering and would be enforceable under CARB’s certification. Staff is recommending the Board to set a public hearing to consider the proposed amendments at its June 2002 meeting.

The Committee members present discussed whether the sunset date should be removed or extended. Since the proposed amendment will be considered by the Board in June, staff suggested that alternative language to extend the sunset date be developed and provide that to the Board for its consideration at the June public meeting in addition to the original recommendation.
 

5) 

Update on Conformity Requirements
Staff reported that as of October 6, 2002, all California Transportation Improvement Program conformity determinations will expire. Federal requirements mandate the use of the latest planning assumptions when making a conformity determination. However, the latest emission budgets are based upon the 1997/1999 AQMP, which were derived from SCAG’s 1994 Regional Transportation Plan (RTP). The 1994 RTP was developed using the most recently approved emissions model, EMFAC 7G.

Two potential scenarios were presented. Scenario #1calls for federal and state stakeholders (EPA, FHWA, CARB) to resolve issues for the 2002 Regional Transportation Improvement Program (RTIP) cycle, which would allow the use of the latest approved SIP assumptions that were developed using the EMFAC 7G model. Staff reported that there are extensive discussions and ongoing coordination between the stakeholders and that a commitment has been made to resolve the problem in one week.

Scenario #2 identifies impacts that could possibly occur if there is no federal/state remedy for this RTIP cycle. The potential impacts would be that since a revised SIP budget through a SIP revision would be difficult, if not impossible, by the October 2002 expiration date, there is the potential of not having a conformity finding, thus forcing the region into a conformity lapse. This lapse could result in the loss of approximately $1.2 billion of federal funding according to SCAG estimates.

In summary, staff identified specific AQMD actions. The first action is to develop the 2002 AQMP in a timely manner in order to establish new budgets. Those new budgets would be developed for the SCAB Ozone and PM10, as well as the Coachella Valley PM10. Staff also indicated that the AQMD is seeking long term solutions to these conformity issues such as better interagency coordination on establishing planning cycles and establishing a more streamlined approach to budget updates.
