### INTRODUCTION
In order to achieve the improvement in ai r quality specified in the AQMP, the control measures listed in the Plan must be adopted and implemented within the timeframes set forth. In the event that implementation of the AQMP is not providing adequate progress and the interim emission reduction goals have not been met, the District must take action to bring forward measures that are scheduled for later adoption or implementation, or to implement certain "contingency" control m easures. These conti ngency measures are control options that could be instituted in addition to the AQMP control measures. Both state and federal Clean Air Acts require that di strict plans include contingency measures.



### CONTINGENCY MEASURES
The 2003 AQMP contains 3 con tingency control measures. Although implementation of these measures is expected to reduce emissions , there are issues that limit the viability of these measures as AQMP control measures at this time. Issues surrounding these measures include, but are not limited to th e availability of District resources to implement and enforce the measure, cost-effe ctiveness of the measure, potential adverse environmental impacts, potential economic impacts, effectiveness of emission reductions, and availability of methods to qua ntify emission reductions . Table 1 lists the contingency control measures and adoption/implementation i ssues associated with the measure. The responsibility to adopt and implement the meas ures falls on the District, CARB, and EPA. A complete discussion of the control measures is included in Appendix IV-A, Section 2; however a su mmary is provided in this chapter.

9 - 2 CTY-01 – ACCELERATED IMPLEMENTATION OF CONTROL MEASURES: Under the 1990 Clean Air Act Amendment, EPA recommends “as a contingency measure the requirement that measures which would take place in later years if the area met its RFP target or attainment deadline, w ould take effect earlier if the area did not meet its RFP target or attainment deadline. ” Thus, in the event the District or Air Resources Board determines that the District failed to either achieve interim emission reduction goals or maintain ad equate progress towards attainment of ambient air quality standards, the District will accelerate the im plementation schedule. This contingency control measure proposes to accelerate th e starting implementation date for the stationary and mobile source control measur es that have implem entation dates on and after 2004. The proposed star ting and revised starting implementation dates of the stationary and mobile source control meas ures affected by this contingency control measure are shown in Table 2. However, the revised dates are not deemed feasible at this time but will be pursued if continge ncy actions are required at a later date.

CTY-04 – ENHANCED OXYGENATED FUELS CONTENT: This contingency control measure proposes to increase the oxyge n content of gasoline sold in the Basin during winter months. The oxygen content would be as hi gh as necessary to offset one years worth of emissions growth associated with increased vehicle miles traveled (VMT). To ensure that impl ementation of this continge ncy control measure does not result in significant increases in NO x emissions, measures can be taken such as avoiding specific types of oxygenates.

CTY-14 – CONTROL OF EMISSIONS FROM MISCELLANEOUS SOURCES: This contingency control m easure proposes future regula tions to require mowing or cutting for weed abatement. Such a requirement would likely be implemented through clarifications and/or additional requi rements through Rule 403 –Fugitive Dust. Additional controls could in clude provisions to limit weed abatement to the early morning hours (winds are typically lower in the morning), lower vehicle speeds or, in instances when mowing is not f easible, require pre-treatment of the site with a watering truck.
