Code of Maryland Regulations › Title 26 - DEPARTMENT OF ENVIRONMENT › Part 2 - SUBTITLES 08-12 › Subtitle 11 - AIR QUALITY › Chapter 26.11.10 - Control of Iron and Steel Production Installations › Section 26.11.10.04 - Particulate Matter

Current through Register Vol. 51, No. 14, July 12, 2024
A. Confined
				  Emissions. A person may not cause or permit the discharge of confined emissions
				  of particulate matter in excess of 0.03 gr/scfd (68.7 mg/dscm) from any iron or
				  steel production installation.
B.
				  Fugitive Emissions.
(1) A person may not
				  cause or permit the discharge of fugitive emissions of particulate matter from
				  an iron and steel production installation unless reasonable control methods are
				  employed to minimize emissions. These methods include the use of hoods and
				  control equipment to capture emissions, other control techniques, and process
				  restrictions.
(2) Reasonable
				  Control Methods Required to Satisfy §B(1) of this Regulation. Reasonable
				  control methods required to satisfy §B(1) of this regulation are listed below
				  for the installation specified, grouped by major buildings or structures. No
				  other control methods are required for those buildings, structures, or
				  installations. The reasonable control methods are:
(a) Blast furnaces constructed before January
				  1, 1977 (casthouse building): regular maintenance of iron notches, troughs, and
				  slag runners;
(b) Blast furnaces
				  constructed on or after January 1, 1977 (casthouse building): iron notch,
				  trough, and slag runners-hoods and control equipment;
(c) Basic oxygen furnace shop building:
(i) Hot metal reladling-hoods and control
				  equipment on the normal hot metal pit and flame suppression on the emergency
				  pit,
(ii) Oxygen lance
				  hole-suppression maintained on all furnace oxygen lance openings;
(iii) Furnace charging, refining, and
				  tapping-use of a primary hood and control equipment with good operating
				  practices and regular maintenance of all system components and
				  ductwork;
(d)
				  Top-charged electric arc furnaces: furnace charging, metal melting, refining,
				  and tapping-hoods and control equipment;
(e) Argon-oxygen decarbonization vessels:
				  vessel charging, refining, tapping, and alloy addition-hoods and control
				  equipment;
(f) Sinter plant
				  building: breaker box, windbox, hot and cold screens, entrance and exit from
				  the sinter cooler, and material handling transfer points-hooded and exhausted
				  into control equipment.
(3) All required reasonable control methods
				  shall be designed to represent good engineering practice and constructed in
				  accordance with the Department's permit to construct approval. The reasonable
				  control methods employed shall be operated and maintained to comply with the
				  visible emission standards set forth in Regulation .03A and B of this chapter
				  and in accordance with any conditions imposed in the Department's permit to
				  operate for that installation.
(4)
				  Emissions from control equipment constructed pursuant to §B(1) and (2) of this
				  regulation, shall meet the requirements of §A of this regulation and Regulation
				  .03A(1) of this chapter.
(5) The
				  discharge of emissions from air pollution control equipment constructed to
				  capture coke oven pushing emissions in accordance with §B(2)(e) of this
				  regulation may not exceed either 0.03 gr/scfd (68.7 mg/dscm) or 0.1 pound/ton
				  (0.05 gram/kilometer) coke pushed, whichever is more restrictive. The pushing
				  period is defined as commencing with the initial movement of coke and
				  terminating with the hot car entering the quench tower.
