Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule

The District was required to adopt a rule for this source category in the Reasonably Available Control Technology

(RACT) State Implementation Plan (SIP) (dated Septe mber 13, 2006), since the District does not current ly have a

prohibitory rule regulating this source category, t here is no control technology guideline (CTG), and the single

existing source subject to this rule is a major sou rce. The rule affects one existing source within t he District that

has a boiler (over 5 MMBtu/hr) that burns biomass f uel. The rule limits nitrogen oxide (NOx) and carb on monoxide

(CO) emissions from biomass fueled boilers by placi ng ppm limits on CO and NOx and requiring continuou s

emission monitors (CEMS) for ongoing monitoring.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

(CO) PM TAC (name):

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: Fulfills 2006 RACT SIP requirement. I s the third of three rules needed for adoption for major sources in

categories not covered by a rule (Expandable Polyst yrene Manufacturing, Nitric Acid Manufacturing, and Biomass Boilers).

No reductions expected since source is already in c ompliance with provisions of the rule.
