Code of Maryland Regulations › Title 26 - DEPARTMENT OF ENVIRONMENT › Part 2 - SUBTITLES 08-12 › Subtitle 11 - AIR QUALITY › Chapter 26.11.38 - Control of NO[x] Emissions from Coal-Fired Electric Generating Units › Section 26.11.38.05 - Compliance Demonstration Requirements

Current through Register Vol. 51, No. 14, July 12, 2024
A. Procedures for Demonstrating Compliance
				  with Regulation .03A of this Chapter.
(1) An
				  affected electric generating unit shall demonstrate, to the Department's
				  satisfaction, compliance with Regulation .03A(2) of this chapter, using the
				  information collected and maintained in accordance with Regulation .03A(1) of
				  this chapter and any additional documentation available to and maintained by
				  the affected electric generating unit.
(2) An affected electric generating unit
				  shall not be required to submit a unit-specific report consistent with §A(3) of
				  this regulation when the unit emits at levels that are at or below the
				  following rates:

(3)
				  The owner or operator of an affected electric generating unit subject to
				  Regulation .03A(2) of this chapter shall submit a unit-specific report for each
				  day the unit exceeds its NOx emission rate under §A(2)
				  of this regulation, which shall include the following information for the
				  entire operating day:
(a) Hours of operation
				  for the unit;
(b) Hourly averages
				  of operating temperature of installed pollution control technology;
(c) Hourly averages of heat input
				  (MMBtu/hr);
(d) Hourly averages of
				  output (MWh);
(e) Hourly averages
				  of ammonia or urea flow rates;
(f)
				  Hourly averages of NOx emissions data (lbs/MMBtu and
				  tons);
(g) Malfunction
				  data;
(h) The technical and
				  operational reason the rate was exceeded, such as:
(i) Operator error;
(ii) Technical events beyond the control of
				  the owner or operator (e.g. acts of God, malfunctions); or
(iii) Dispatch requirements that mandate
				  unplanned operation (e.g. start-ups and shut-downs, idling, and operation at
				  low voltage or low load);
(i) A written narrative describing any
				  actions taken to reduce emission rates; and
(j) Other information that the Department
				  determines is necessary to evaluate the data or to ensure that compliance is
				  achieved.
(4) An
				  exceedance of the emissions rate under §A(2) of this regulation as a result of
				  factors including but not limited to start-up, shut-down, days when the unit
				  was directed by the electric grid operator to operate at low load or to operate
				  pursuant to any emergency generation operations required by the electric grid
				  operator, including necessary testing for such emergency operations, or which
				  otherwise occurred during operations which are deemed consistent with the
				  unit's technological limitations, manufacturers' specifications, good
				  engineering and maintenance practices, and good air pollution control practices
				  for minimizing emissions, shall not be considered a violation of Regulation
				  .03A(2) of this chapter provided that the provisions of the approved plan as
				  required in Regulation .03A(1) of this chapter are met.
