EPA is proposing national emission
standards for hazardous air pollutants for gold mine ore processing
and production. The proposed rule applies to gold mine facilities
engaged in processing gold ore to recover gold using one or more of
the following process units: roasters, autoclaves, carbon kilns,
melt furnaces, retorts, electrowinning, and/or pregnant tanks; and
have the potential to emit mercury for which the source category
was listed. All gold mine facilities subject to the rule would be
required to comply with emission standards for mercury. The
standards are based on the maximum achievable control technology
for this source category. Gold mine facilites subject to emission
standards would be required to conduct a performance test to
demonstrate annual compliance with the mercury standard. Monitoring
requirements for gold mine facilities with roasters would include
either continuous monitoring of mercury emissions from roaster
stacks or weekly samples of mercury concentration, both coupled
with parametric monitoring of the mercuric chloride scrubbers on
roasters. EPA is proposing three options for monitoring
requirements for gold mine facilities with processes controlled by
carbon adsorbers: (1) sampling of the exit stream from the carbon
bed for mercury, (2) sampling the carbon for adsorbed mercury, and
(3) replacing the bed at specified intervals based on historical
data on carbon bed life. The inlet to the carbon adsorber would
also be monitored for temperature. For wet scrubbers, EPA is
proposing that the water flow rate and scrubber pressure drop be
monitored. Potential respondents include 21 existing gold mine ore
processing and production facilites; no new gold mine facilites are
expected during the 3-year clearance period of this ICR. Total
annual responses attributable to this ICR for existing sources are
two one-time notifications; notification of applicability and
notification of compliance status. The final rule allows 2 year
after promulgation for existing gold mine ore processing and
production facilities to comply with these requirements.
EPA is under court order to
propose standards for gold mine ore processing and production
facilities. This increase burden results from a new rule 40 CFR
part 63, subpart EEEEEEE under section 112 of the Clean Air
Act.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
