EPA HAZARDOUS AIR POLLUTANT STANDARDS: SUMMARY INTERPRETATION
A . GENERAL
Asbestos, beryllium and mercury have been declared hazardous air pollutants and national standards have been promulgated (Federal Register, V. 38, no. 66, pp 8820-8850, April 6, 1973). No one may construct or modify any stationary hazardous air pollutant source, and all existing sources must register with EPA. In Maryland, the address to contact is:
Director, Enforcement Division Environmental Protection Agency Region III Curtis Building Sixth and Walnut Streets Philadelphia, Pa. 19106
B. ASBESTOS
(1) Mills, manufacturing plants - no visible emissions except [what would get through a well-designed baghouse]. The wording is that the fabric filter must operate at up to a pressure drop o 4 in. water gage and have air flow permeability no greater than 30 cfm'/ft. of cloth. T^is corresponds to an operating air to cloth ratio of under 3.0 cfm/ft. (see AP-51, p. 105).
EPA officials say they put in the baghouse design specifications to effectively assure that these sources would be well controlled.
(2) Demolition - Any demolition operator wishing to raze any institutional, commercial, or industrial building (including apartment buildings with more than 4 dwelling units) must notify the EPA Administrator at least 20 days in advance, including the information listed under 61.22 (d)(1). The procedures to be followed to reduce asbestos emissions in demolition are basically (1) wet and remove fireproofing insulation from all boilers, pipes, and load-supporting structural members, and (2) do not drop these friable asbestos materials but lower carefully or transfer to ground via dust-tight containers or chutes.
(3) Sprayed asbestos - spray on materials used to insulate or fireproof buildings shall contain less than 1% asbestos on a dry weight basis.

RULES AND REGULATIONS
(g) "Denuder" means a horizontal or vertical container which is part of a mer cury chlor-alkali cell and in which water and alkali metal amalgam are converted to alkali metal hydroxide, mercury, and hydrogen gas in a short-circuited, elec trolytic reaction.
(h) "Hydrogen gas stream"' means a hydrogen stream formed in the chlor alkali cell denuder.
. (i) "End box" means a container(s) located on one or both ends of a mercury chlor-alkali electrolyzer which serves as a connection between the electrolyzer and denuder for rich and stripped amalgam.
<j ) "End box ventilation system" means a ventilation system which col lects mercury emissions from the endboxes, the mercury pump sumps, and their water colection systems.
,(k) "Cell room" means a structure(s) housing one or more mercury electro lytic chlor-alkali cells.
61.52 Emission standard.
Emissions to the atmosphere from sta tionary sources subject to the provisions of this subpart shall not exceed 2,300 grams of mercury per 24-hour period. 61.53 Stack sampling.

a new source which has an initial start up date preceding the effective date; or
(ii) Within 90 days of startup in the

an initial startup date preceding the ef
fective date.
.
(2) The Administrator shall be noti fied at least 30 days prior to an emission
test, so that he may at his option observe the test.
(3) Samples shall be taken over such a period or periods as are necessary to
accurately determine the maximum emissions which will occur in a 24-hour period. No changes in the operation shall be made, which would potentially in
crease emissions above that determined by the most recent source test, until the new emission level has been estimated by calculation and the results reported "to the Administrator.
(4) All samples shall be analyzed, and mercury emissions shall be determined within 30 days after the source test. Each determination will be reported to the Ad ministrator by a registered letter dislatched before the close of the next busi ness day following such determination.
(5) Records of. emission test results and other data needed to determine total
emissions shall be retained at the source
