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

This rule implements Federal and State NOx RACT/BARCT requirements for boilers, steam generators and process

heaters.

This rule amendment removed the language referring to the thr ee previous calendar years in the Section 300, Standards

as follows:

Revised Standard 301, Annual Heat Input > 90,000 Therms, to be determined based on annual heat input for the year

instead of any of the three previous y ears. This changes the standard to be based on the prior year not on the previous

three years.

Revised Standard 302, Annual Heat Input <90,000 Ther ms, to be determined based on annual heat input for the

one prior year instead of each of the three previous years.

There were no new emission reductions associated with this amendment.

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

(CO) PM TAC (name):

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No

If Yes, Those Limits are in Section(s) 301 of the Rule.

Other Methods in the Rule for Achieving Emission Reductions are: Annual tuning is required for units which burn less

than 90,000 therms.

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): 301 Work Practice Standards in Section(s): 303 and 600

Recordkeeping Requirements in Section(s): 500 Reporting Requirements in Section(s): 503CALIFORNIA AIR RESOURCES BOARD

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: This amendment changed the time period from a three year to an annual period used to determine if heat

input was greater than or less than 90,000 therms. If less t han 90,000 therm heat input were burned in the prior year, the

unit shall be tuned annually.
