Md. Code Regs. 26.11.10.04 - Particulate Matter
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.
C. Skull
Cracker Oxygen Lancing. A person may not cause or permit the oxygen lancing of
iron and steel scrap in excess of 400 tons each year. This oxygen lancing is
limited to the months of December, January, and February.
