Md. Code Regs. 26.11.15.04 - Requirement to Quantify Emissions
A. New Installations or Sources.
(1) The owner or operator of a new
installation or source shall quantify emissions of each TAP that will be
discharged and submit that information to the Department when applying for the
permit to construct the new installation or source, or when an update is
requested by the Department.
(2)
Emissions shall be quantified in sufficient detail to determine whether the
premises complies with the requirements of this chapter.
B. Existing Installations or Sources.
(1) The owner or operator of an existing
installation or source that, on or before March 1, 1993, either has obtained or
was required to obtain a State permit to operate shall quantify emissions of
each toxic air pollutant that is discharged that is listed in COMAR
26.11.16.06 a and .07B.
(2) Emissions shall be quantified in
sufficient detail to determine whether the premises complies with the
requirements of this chapter.
(3)
An owner or operator of an existing installation or source shall submit
emissions data not later than 1 year after becoming subject to this chapter or
not later than the following dates, whichever is later:
(a) January 1, 1989, for Class I toxic air
pollutants listed in COMAR
26.11.16.06 a;
(b) January 1, 1989, for Class II toxic air
pollutants listed in COMAR
26.11.16.07 a B with a compliance
date of July 1, 1990; and
(c)
January 1, 1991, for any other Class II toxic air pollutants listed in COMAR
26.11.16.07 a B.
C. Certain Exempt
Sources.
(1) Certain Premises Discharging
Small Quantities of TAP. The owner or operator of a premises exempted from
certain requirements under Regulation .03B(3)(a) or (b) of this chapter shall
quantify emissions as required by §A or B of this regulation in sufficient
detail to demonstrate the Department's satisfaction that emissions are less
than the applicable emission rates listed in Regulation .03B(3)(a) or (b) of
this chapter.
(2) Other Sources
Exempt from Regulations .05 or .06. The owner or operator of a NESHAP source or
other installation, source, or premises exempted from certain requirements
under Regulation .02B, .03B(3)(c), or .03B(4) of this chapter shall quantity
emissions as required by §A or B of this regulation.
D. Level of Detail.
(1) An initial screening analysis under COMAR
26.11.16.02 a A may be based on a
conservative estimate of emissions that represents good engineering judgment,
if the Department determines that the analysis demonstrates applicable
screening levels will not be exceeded. If compliance with Regulation .06 of
this chapter cannot be demonstrated on this basis, more precise emission
estimates shall be used.
(2) An
owner or operator of a source that discharges more than one toxic air pollutant
may demonstrate compliance with Regulation .06 of this chapter by:
(a) Quantifying emissions and performing
modeling for each TAP individually;
(b) Using procedures approved by the
Department to quantify TAP emissions and perform modeling for a group of TAPs,
and to evaluate concentrations on the basis of the toxicity of the most toxic
component or components of the group; or
(c) Using other procedures approved by the
Department.
(3) If
several related substances are listed as Class I TAPs or are members of a group
of substances listed as a Class I TAP, and these substances are evaluated using
a common upper bound unit risk factor, then the substances shall be considered
together as one TAP. For example, all hexavalent compounds of chromium that
have been determined to be carcinogens shall be considered together as one TAP.
Also, dioxin and furan emissions shall be considered together as one TAP and
expressed as an equivalent emission of 2,3,7,8-tetrachlorodibenzo-p-dioxin
based upon the relative potency of the isomers.
