URBAN AIR TOXICS – AREA SOURCE PROGRAM SALLY SHAVER, DIRECTOR EMISSION STANDARDS DIVISION October 5, 2004

STATUTORY AUTHORITY (CLEAN AIR ACT)  Sections 112(c)(3) and 112(k)(3)(B)(ii)  List area source categories representing at least 90 percent of the emissions of the 30 listed HAP  Promulgate regulations by November 15, 2000  Section 112(d)(5) allows us to address source categories using GACT (Generally Available Control Technology)

STATUTORY AUTHORITY (CLEAN AIR ACT) (CONTINUED)  Section 112(k)(1)  Achieve a substantial reduction in emissions of HAPs  Achieve at least a 75-percent reduction in cancer incidence  Section 112(k)(3) requires us to prepare a national strategy for urban air toxics  The Integrated Urban Strategy was published July 19, 1999 (64 FR 38706)

RULEMAKING  Area sources are those with potential to emit less than 10 tpy for a single HAP and less than 25 tpy for combined HAP  Standards may be MACT or GACT  MACT is average of the best performing 12% (30 or more sources) or average of best performing five (< 30 sources)  GACT is no MACT floor, may be less stringent than MACT, and may consider costs and other factors  Typical standard development takes 4 to 5 years

CONTRIBUTIONS TO EMISSIONS AND RISK  Individual area sources are small emitters  Many sources emit less than 100 pounds of HAPs  Collectively, these sources are important toxic contributors, especially in urban areas  Area sources represent about 50 percent of national stationary source emissions  Many sources emit air toxic metals which are also fine PM

AREA SOURCE PROGRAM  “Child No One Wants”  70 categories listed  15 standards completed; consent decree to complete 5 more by December 2007  Ongoing litigation/mediation 30 area source standards have been started; includes top 20 “toxicity weighted”  Area Source Emission Reduction Initiative  Community-Based Projects

URBAN AIR TOXICS – AREA SOURCE RULES (continued)  Held a meeting with Air Program Managers from all Regions Consensus that we need the area source program Needs to be flexible, self-implementing and self-certifying Must say selectivity is OK EPA does not want/need Title V to implement the area source program Program Emphasizes Results EPA wants to explore the concept of a State Program with targeted applicability for CTGs

CURRENTLY DEFERRED FROM TITLE V 1. Dry cleaners (30,000+ sources) 2. Degreasers (3,800 sources) 3. Chrome platers (5,000 sources) 4. EO sterilizers (40 sources) 5. Secondary lead smelters (3 sources) 6. Secondary aluminum production facilities (2,700 sources)
