### Maintenance Plan Motor Vehicle Emissions Budget s

September 10, 2012 *

1. The initial Tier 1 MVEBS are based on mobile emissions inventory projections for 2017 and 2025, with 28 tons added to the 2025 PM2.5 budget to enable conformity with the 2040 horizon year. The primary Tier 2 MVEBS have 20% transportation buffers applied to all pollutants i n 2017 and 2025. The transportation buffers are provided to accommodate uncertainties primarily due to model changes and to vehicle fleet turnover that may affect future motor vehicle emissions inventories

2. The Washington DC

- MD

- VA area commits to evaluat ing and submitting, as a revision to the 1997 PM 2.5 NAAQS maintenance plan, updated annual 2017 and 2025 MVEBs for NOx and PM 2.5 by the end of 2015. These budgets will again be re

- evaluated in the 2018 timeframe to
acco m m o date transportation planning issue s when the Constrained Long Range Plan horizon year is extended beyond 2040

.

3. The Washington DC

- MD

- VA area commits to begin planning to identify appropriate strategies to help the area achieve and maintain compliance with a potential bump

- up of the region to a moderate classification for the 2008 ozone NAAQS, as well as any future ozone NAAQS . This planning process will includ e, but is not limited to , the development of a preliminary 15% Rate of Progress Plan.

4. The Washington DC

- MD

- VA area will work with jurisdictions and EPA to demonstrate the feasibility of (and get SIP credit fo r) achieving reductions across the entire region from market forces that will result in cleaner products being distributed across the entire region even when the regulations driving the cleaner products have only been adopted in a part of the region.



### 5. Mary land and the District of Columbia will work to adopt at least five new regulations to insure that, to the extent the transportation buffers are triggered, that there is no environmental degr a dation in the Maryland and the District of Columbia portions of the nonattainment area. These new measures will also begin the process of further reducing ozone and fine particle levels in the region to insure that public health is protected. Maryland and the District agree with the scientific community who believe that more stringent ozone and fine particle standards are needed. The new regulatory programs include low sulfur home heating fuel, enhancements to current controls on consumer products and industri al adhesives, off

- road idling, and tougher requirements for smaller boilers (i.e. d ie sel generators) that are, in some circumstances, receiving a financial incentive to run their small generators on the hottest days, which correlate with the worst ozone da ys. The commitments made by Maryland and the District will not be construed to infringe upon any prerogative of the Commonwealth of Virginia. Virginia will pursue measures that are necessary to attain and maintain current and future air quality standards a s well as measures that may decrease the burden on regulated parties. For instance, Virginia is committed to pursue measures such as the on

- road emissions program, which will

- road monitoring could also result in the early identification and repair of high emitting vehicles so that this program w ill maintain environmental protections as well as reduce the time required for station

- based tests. Virginia is also committed to supporting voluntary efforts to reduce energy consumption through energy efficiency and renewable energy programs. Organizat ions, such as the nonprofit Local Energy Alliance Program (LEAP), run residential and commercial programs in Northern Virginia that seek to reduce energy use by at least 20 percent, saving consumers money, conserving resources, and decreasing air emissions
