The BTU-weighted 30-day rolling average NOX emission rate for the affected units shall be less than or equal to 0.21 pounds per million BTU of heat input, during the compliance period specified in paragraph (3) below.

(3) Beginning May 1, 2003, and each year thereafter, the compliance period shall begin May 1 and end on September 30 of each year. Compliance is based on a 30-day rolling average.

(b) The last calculated 30-day averaging period shall be September 1 through September 30.

(4) Testing, Recordkeeping and Reporting.

(a) Continuous emissions monitoring systems (CEMS) to measure nitrogen oxide emissions from each affected unit shall be installed and operated at locations approved by the Director. The CEMS shall meet the specifications and procedures of 40 CFR Part 75 and will be certified and maintained in accordance with 40 CFR Part 75 . In addition, each of the CEMS shall undergo a relative accuracy test audit (RATA) on an annual basis at times approved by the Director.

(b) Records of the 30-day average nitrogen oxide emission rate for the affected units shall be kept for a period of five (5) years.

(c) A written report of the 30-day average nitrogen oxide emission rates for the affected units shall be submitted to the Department by the 15th day of each month during the period from May 1 to September 30 of each year. The first report shall be submitted by June 15 and shall include data for the month of May. The final report shall be submitted by October 15 and shall include data for the month of September.

(d) Any exceedances of the NOX emission rate specified in paragraph (2) of this Rule shall be reported to the Department within two (2) working days of the date of the exceedance.

(e) Additional testing, recordkeeping, and reporting requirements may be necessary and will be specified by the Director at such times as they become necessary.
