                           Subpart A--General
 
Sec. 75.1  Purpose and scope.


    (a) Purpose. The purpose of this part is to establish requirements 
for the monitoring, recordkeeping, and reporting of sulfur dioxide 
(SO2), nitrogen oxides (NOX), and carbon dioxide 
(CO2) emissions, volumetric flow, and opacity data from 
affected units under the Acid Rain Program pursuant to sections 412 and 
821 of the CAA, 42 U.S.C. 7401-7671q as amended by Public Law 101-549 
(November 15, 1990) [the Act]. In addition, this part sets forth 
provisions for the monitoring, recordkeeping, and reporting of 
NOX mass emissions with which EPA, individual States, or 
groups of States may require sources to comply in order to demonstrate 
compliance with a NOX mass emission reduction program, to the 
extent these provisions are adopted as requirements under such a 
program.
    (b) Scope. (1) The regulations established under this part include 
general requirements for the installation, certification, operation, and 
maintenance of continuous emission or opacity monitoring systems and 
specific requirements for the monitoring of SO2 emissions, 
volumetric flow, NOx emissions, opacity, CO2 
emissions and SO2 emissions removal by qualifying Phase I 
technologies. Specifications for the installation and performance of 
continuous emission monitoring systems, certification tests and 
procedures, and quality assurance tests and procedures are included in 
appendices A and B to this part. Criteria for alternative monitoring 
systems and provisions to account for missing data from certified 
continuous emission monitoring systems or approved alternative 
monitoring systems are also included in the regulation.
    (2) Statistical estimation procedures for missing data are included 
in appendix C to this part. Optional protocols for estimating 
SO2 mass emissions from gas-fired or oil-fired units and 
NOx emissions from gas-fired peaking or oil-fired peaking 
units are included in appendices D and E, respectively, to this part. 
Requirements for recording

and recordkeeping of monitoring data and for quarterly electronic 
reporting also are specified. Procedures for conversion of monitoring 
data into units of the standard are included in appendix F to this part. 
Procedures for the monitoring and calculation of CO2 
emissions are included in appendix G of this part.
