ENVIRONMENTAL PROTECTION AGENCY Office of Air and Radiation 40 CFR Part 75 [RIN] Acid Rain Program: Announcement of Open Meeting on Continuous Emission Monitoring (CEM) Data Acquisition and Handling Systems (DAHS) Certification, and Electronic and Magnetic Data Reporting for the CEM Rule AGENCY: Environmental Protection Agency (EPA) ACTION: Notice of meeting SUMMARY: Title IV of the Clean Air Act (the Act), as amended November 15, 1990, requires the Environmental Protection Agency (EPA or Agency) to establish an Acid Rain Program to reduce the adverse effects of acidic deposition. To implement this statutory mandate, the Acid Rain Program relies on three basic components: the acid rain permit, the market-based allowance system, and continuous emissions monitoring (CEM). The CEM component is critical to provide accurate emissions measurements which ensure source compliance with the reductions mandated under the Act. The CEM regulations, promulgated in the Federal Register on January 11, 1993, require electric utilities to submit certification applications which include results for the verification of the calculations performed by their data acquisition and handling system (DAHS). The Environmental Protection Agency will hold a meeting to discuss the procedures for DAHS certification and auditing, and electronic data reporting and data processing procedures being developed pursuant to implementation of the reporting provisions contained in the CEM Rule (40 CFR Part 75). DAHS vendors, data processing staff from affected utilities, CEM manufacturers, and other interested parties are encouraged to attend. There is no fee for attendance, however, pre-registration by telephone facsimile is required. A letter stating the attenders' names, addresses, telephone numbers, and affiliation should be sent by telephone facsimile by Friday, July 9, 1993 to Sharon Saile, Continuous Emission Monitoring Section, USEPA/OAR/ARD/SAB at 202-233-9584/9585/9586. DATES: The meeting will be held on Wednesday, July 14, 1993, from 9:00 am until 4:30 pm, and if necessary will be repeated on Friday, July 16, 1993 from 9:00 am until 4:30 pm. ADDRESSES: The meeting will be held in the auditorium located at the Environmental Protection Agency, Waterside Mall, 401 M Street, S.W., Washington, D.C. 20460. FOR FURTHER INFORMATION CONTACT: Sharon Saile, Acid Rain Division (6204J), U.S. Environmental Protection Agency, 401 M. Street, S.W., Washington, DC 20460, (202)-233-9180. SUPPLEMENTARY INFORMATION: Attendees must pre-register by telephone facsimile by Friday, July 9, 1993. If pre-registration exceeds the available conference room space for 140 attendees, a second day (to repeat the first day) will be held on Friday, July 16, 1993 from 9:00 am until 4:30 pm. Because seating may be limited, pre-registration for Friday will be limited to persons who were not able to attend the meeting on Wednesday; seats will be provided for repeat participants (or for those who have not pre-registered) on a first-come, first-served basis.
