The program has substantially reduced sulfur dioxide emissions and nitrogen oxide emissions from electric utility plants. These emissions reductions have been achieved at low cost to society, by employing both traditional regulatory techniques and innovative, market-based approaches. The centerpiece of the program is the allowance trading system, under which affected utility units a","cbCaikAKmN8RinyU","https://ap.wps.com/l/cbCaikAKmN8RinyU","pdf",1828477,365,"English","# Introduction\n## Section 1--General\n## Section 2--SO2 Monitoring\n## Section 3--Flow Monitoring\n## Section 4--NOx Monitoring\n## Section 5--Opacity Monitoring\n## Section 6--CO2 Monitoring\n## Section 7--Backup and Portable Monitoring\n## Section 8--Relative Accuracy\n## Section 9--Span, Calibration, and Linearity\n## Section 10--Other QA/QC Requirements\n## Section 11--Certification: Administrative/Procedural\n## Section 12--Recertification\n## Section 13--DAHS, Recordkeeping, and Reporting\n## Section 14--Missing Data Procedures\n## Section 15--Add-On Emission Controls and Parametric Monitoring\n## Section 16--Common, Multiple, and Complex Stacks\n## Section 17--Conversion Procedures\n## Section 18--Applicability\n## Section 19--Reference Methods as Backup Monitors\n## Section 20--Subtractive Configurations\n## Section 21--Bypass Stacks\n## Section 22--NOx Apportionment\n## Appendix A--Miscellaneous Support Documents\n## Appendix B--October 2003 Policy Manual Crosswalk","[{\"question\":\"What is the purpose of the Part 75 Emissions Monitoring Policy Manual?\",\"answer\":\"It provides a series of Questions and Answers to ensure Part 75 emissions monitoring and reporting requirements are applied consistently nationwide for affected sources.\"},{\"question\":\"Why does the Acid Rain Program require continuous measurement of SO2 emissions?\",\"answer\":\"Accurate determination of actual emissions is necessary to ensure allowances are valued consistently and projected emission reductions are achieved, as Title IV requires continuous measurement and recording of SO2 mass emissions.\"},{\"question\":\"How is the manual maintained over time?\",\"answer\":\"It is intended as a living document, with the EPA issuing new Questions and Answers and revising previously issued ones as needed; newly edited items are marked with a “Revised” stamp.\"}]","Part 75 Emissions Monitoring Policy Manual - Section 75 Questions and Answers | PDF",920]
