PART 1 GENERAL

1.1 Purpose

The purpose of this Rule is to provide requirements and standards for continuous emissions monitoring systems (CEMS).

1.2 Applicability

The provisions of this Rule shall apply to: electric power generation equipment subject to Title IV (Acid Deposition Control) of the federal Clean Air Act with nameplate generation capacities of at least 25 megawatts (MW); to fossil fuel-fired steam generators with a rated heat input of 250 million British thermal units (MMBtu) or greater per hour; and to any source required to install CEMS as required to prove compliance with air pollution requirements pursuant to an Authority to Construct or Permit to Operate issued by the District.

1.3 Exemptions

1.3.1 For peaking units subject to this Rule, the NOx emissions concentrations may be measured and recorded using one of the methods provided under 40 Code of Federal Regulations (CFR) Part 75, Section 75.12(c) "Specific Provisions for Monitoring NOx Emissions (NOx and Diluent Gas Monitors: Gas-fired Peaking Units or Oil- fired Peaking Units"), rather than by CEMS as required by Part 3 herein.

1.4 Effective Dates

This Rule has been in effect since June 22, 1977. The Rule in its present form is effective on March 21, 2001.

1.5 References

The requirements of this Rule arise from the provisions of the federal Clean Air Act and its amendments (42 U.S.C. Section 7401 et seq.) and California Health and Safety Code Sections 40702 and 42706.

PART 2 DEFINITIONS


Unless otherwise defined within this Part, the definitions used for the purposes of this Rule shall be those given in 40 CFR Parts 51, 60, 72, or 75.


2.1 Air Resources Board (ARB)

State of California Air Resources Board.

2.2 Authority to Construct (ATC)

A written permit issued by the District to a specific applicant prior to the building, erection, alteration, or replacement of any article, machine, equipment or other contrivance which may cause the issuance of air contaminants or the use of which may eliminate, reduce or control the issuance of air contaminants.

2.3 Continuous Emissions Monitoring System (CEMS)

The total equipment required for the continuous determination and record keeping of a gas concentration, emission rate or opacity measurement.

2.4 District

The Monterey Bay Unified Air Pollution Control District (MBUAPCD).

2.5 Emissions

The quantitative rate of releases to the atmosphere from an emission point as measured by the continuous emissions monitoring system (CEMS) and calculated by the methods specified in the Permit to Operate.

2.6 Nitrogen Oxides (NOx)

The sum of the molecular forms of nitrogen oxide and nitrogen dioxide. When measured or calculated, the total of the two molecular forms is collectively expressed as nitrogen dioxide.

2.7 Peaking Unit

Electric power generation equipment subject to Title IV of the federal Clean Air Act which has:

2.7.1 an average capacity factor of no more than ten (10) percent during the previous three (3) calendar years; and

2.7.2 a capacity factor of no more than 20 percent in each of those calendar years.

2.8 Permit to Operate

A written permit, with any specified conditions required, issued by the Monterey Bay Unified Air Pollution Control District to a specific applicant for the operation or use of any article, machine, equipment or other contrivance which may cause the issuance of air contaminants or the use of which may eliminate, reduce or control the issuance of air contaminants.

2.9 Sulfur Oxides (SOx)

The sum of the molecular forms of sulfur oxide and sulfur dioxide. When measured or calculated, the total of the two molecular forms is collectively expressed as sulfur dioxide (SO2).

PART 3 REQUIREMENTS AND STANDARDS FOR SOURCES SUBJECT TO TITLE IV
OF THE FEDERAL CLEAN AIR ACT

By January 1, 1995, the owner or operator of electric power generation equipment subject to Title IV (Acid Deposition Control) of the federal Clean Air Act, and with nameplate generation capacities of at least 25 MW, shall properly install, certify, operate and maintain in good working order continuous emissions monitoring systems which meet the standards of 40 CFR Parts 72 and 75.


PART 4 REQUIREMENTS AND STANDARDS FOR OTHER SOURCES

4.1 Other Sources

The owner or operator of the sources listed herein shall properly install, certify, operate and maintain in good working order continuous emissions monitoring systems (CEMS) to measure and maintain records of the pollutants listed in Subsections 4.2.1, 4.2.2 and 4.2.3 herein, unless the source is subject to the provisions of Part 3 herein.
