The owner or operator of a nonmetallic mineral processing plant
must use the Best Management Practices (BMP) contained in Section
799 to control the emissions of
fugitive dust. Fugitive dust emissions must be reasonably controlled as
required by Sections 650 and
651. It is the responsibility of
the owner or operator to reasonably control fugitive emissions at each site of
operations but only for the duration of operations at each site under the
control of the owner or operator. (3-28-23)
01.
Generally Applicable
Requirements. All reasonable precautions must be taken to prevent
particulate matter from becoming airborne. (3-28-23)
a. The owner or operator of a nonmetallic
mineral processing plant must at all times be observant of all sources of
fugitive dust emissions and monitor control strategies at least once per day
when operating. The following events will trigger initiation of the prescribed
control strategy or control strategies to control the fugitive dust emissions.
(3-28-23)
i. When fugitive dust emissions are
observed at any time to be exceeding any control strategy trigger specified in
Subsections 799.02 through
799.06, that event triggers
initiation of the prescribed control strategy or control strategies to control
the fugitive dust emissions. (3-28-23)
ii. Citizen complaints of failure to
reasonably control fugitive dust must be expeditiously evaluated by the owner
or operator for merit. If the owner or operator determines the complaint has
merit, the progressive strategy must be expeditiously employed to reasonably
control fugitive dust. The Department may review the complaint records and
investigate citizen complaints as appropriate. If the Department finds that a
complaint has merit, it may determine additional control measures are required.
(3-28-23)
b. A
progressive control strategy must be used to reasonably control the emissions
of fugitive dust. Progressive control strategy means that if the initial
control strategy or strategies chosen do not adequately control fugitive dust
emissions, the owner or operator must employ successive control strategies as
listed until fugitive dust control is achieved. Fugitive dust control must be
applied on a frequency such that visible emissions do not exceed any emission
standard specified in Sections
790 through
799. (3-28-23)
c. The owner or operator must maintain a
record of each event where a control strategy is triggered. The trigger must be
recorded with a summary of the control strategy employed. If the trigger is a
citizen complaint, the owner or operator must record the complaint, an
evaluation of whether the complaint has merit, and a summary of the corrective
action taken. The record must be maintained on forms provided by the Department
or other forms that contain similar information. Records for current operations
must be maintained at the site of operations for the duration of operations at
that location and must be available to Department representatives upon request.
Records for previous sites of operation must be kept for the most recent two
(2) year period at a location where they can be reasonably accessed and must be
made available to the Department upon request. (3-28-23)
02.
Requirements for Paved Public
Roadways. (3-28-23)
a. Definitions.
(3-28-23)
i. A paved public roadway means a
roadway accessible to the general public having a surface of asphalt or
concrete. (3-28-23)
ii. Track-out
means the deposition of mud, dirt, or similar debris onto the surface of a
paved public roadway from the tires and/or undercarriage of any vehicle
associated with the operation of a nonmetallic mineral processing plant.
(3-28-23)
b. Control
strategy triggers that require initiation of a strategy or strategies to
control fugitive dust emissions from track-out include, but are not limited to:
(3-28-23)
i. Visible deposition of mud, dirt,
or similar debris on the surface of a paved public roadway. (3-28-23)
ii. Visible fugitive emissions from vehicle
traffic on an affected paved public roadway that approach twenty percent (20%)
opacity for a period or periods aggregating more than one (1) minute in any
sixty (60) minute period. (3-28-23)
c. The following are control strategies for
track-out. (3-28-23)
i. Prompt removal of mud,
dirt, or similar debris from the affected surface of a paved public roadway.
(3-28-23)
ii. Water flush, and/or
water flush and vacuum sweep, the affected surface of the paved public roadway.
Runoff must be controlled so it does not saturate the surface of the adjacent
unpaved haul road such that track-out is enhanced. If runoff is not, or cannot
be controlled, gravel must be applied to the surface of the adjacent unpaved
haul road over an area sufficient to control track-out. (3-28-23)
iii. Apply gravel to the surface of the
adjacent unpaved haul road. The area of application must be sufficient to
control track-out. (3-28-23)
iv.
Apply an environmentally safe chemical soil stabilizer or chemical dust
suppressant to the surface of the adjacent unpaved haul road. The area of
application must be sufficient to control track-out. (3-28-23)
v. Other control strategy or strategies as
approved by the Department. (3-28-23)
03.
Requirements for Unpaved Haul
Roads. (3-28-23)
a. Unpaved haul roads
are defined as any unsurfaced roadway within the physical boundary of a
nonmetallic mineral processing facility that is used as a haul road, access
road, or similar. (3-28-23)
b.
Control strategy triggers that require initiation of a strategy or strategies
to control fugitive dust emissions from unpaved haul roads include, but are not
limited to visible fugitive emissions from vehicle traffic on unpaved haul
roads that approach twenty percent (20%) opacity for a period or periods
aggregating more than one (1) minute in any sixty (60) minute period.
(3-28-23)
c. The following are
control strategies for fugitive dust emissions from unpaved haul roads.
(3-28-23)
i. Limit vehicle traffic on unpaved
haul roads. (3-28-23)
ii. Limit
vehicle speeds on unpaved haul roads. If a speed limit is imposed, signs must
be posted along the haul road route and clearly indicate the speed limit. Signs
must be placed so they are visible to vehicles entering and leaving the site of
operations. (3-28-23)
iii. Apply
water to the surface of the unpaved haul road. Runoff must be controlled so it
does not saturate the surface of the unpaved haul road such that it causes
track-out. If runoff is not, or cannot be controlled, gravel must be applied to
the surface of the unpaved haul road over an area sufficient to control
track-out. (3-28-23)
iv. Apply
gravel to the surface of the unpaved haul road. (3-28-23)
v. Apply an environmentally safe chemical
soil stabilizer or chemical dust suppressant to the surface of the unpaved haul
road. (3-28-23)
vi. Other control
strategy or strategies as approved by the Department.
