(NAAQS)

New Particulate Matter Standards 

(PM) in 2006

–Consideration of new indicators

CO, Pb, and PM reviews ongoing
STANDARDS IMPLEMENTATION

 Revised ozone and PM standards in 1997

– Ozone SIPs due in 2007, PM SIPs in 2008

– Attainment dates for ozone 2007-2024

– Attainment dates for PM 2010-2015

AIR ISSUES

 Implementation of NAAQS

Ammonia not regulated as a 

precursor of PM2.5

Exceptional Events Rule – Treatment 

of data due to natural events (fire, 

wind)

Regulation of pesticide use to reduce 

VOC emissions

Revision of Fire Policy
FIRE POLICY

 The 1998 Interim Wildland and Prescribed Fire Policy

does not address agriculture burning

 EPA committed to revising this policy by July 2008

 Revisions will

– Make policy consistent with the Exceptional Events 

Rule

– Address agricultural burning

– Reflect new NAAQS, conformity, and regional haze

– Be developed by seeking input from ag community

at state and local level –Agency has initiated 

dialogue with NASDA
STATIONARY SOURCE ISSUES

 Applicability of CAA requirements to farms

– Source definition issue

 What is an affected facility? (ownership, common control, 

support facility, etc.)

Case-by-case determinations made considering multiple factors.

– Fugitive emissions – Cannot reasonably pass through a 

stack, chimney, vent or other functionally equivalent opening

 Industrial/Commercial Boiler MACT rule and CISWI 

rule vacated

– Solid Waste Definition

 OSWI rule vacated

– Disposal of mortalities at AFOs
MOBILE SOURCE ISSUES

 Proposed Rule for renewable fuels standard 

program required under EISA of 2007

 Locomotive and marine engines standards

– March 14, 2008

 Spark ignition marine engines, small landbased engines, and category 3 marine 

engines rules

 Engine testing program
MOBILE SOURCE ISSUES

 Voluntary Partnership Programs to reduce 

emissions from in-use engines and fleets

– SmartWay Transport Partnership

– SmartWay Heavy Duty Truck Emissions 

Initiative

 National Clean Diesel Campaign

– $49.2M for FY08

 $34.4M Direct grants

 $14.8M for state programs
ATMOSPHERIC PROGRAMS

 Climate Change

– Greenhouse Gases Inventory
