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

  2. 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)

  3. 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)

  4. 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

  5. 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

  6. 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

  7. 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

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