Piceance Fugitive Dust Control Plan (FDCP)
Document No. PBSR- ALL- CIV- SPC -tJRS- 00000 - 04013 -00
Revised March 11, 2009
The scope of this document is to outline the basic requirements to minimize and
control fugitive dust emissions during land development activities. These
guidelines will be reviewed periodically and will be shared with employees and
contractors to ensure that they have adequate knowledge to minimize fugitive dust
emissions.
Introduction
Land development activities, including clearing, excavating, and grading, release
dust to the atmosphere. This fugitive dust is regulated as an air pollutant by the
Air Pollution Control Division (APCD) at the Colorado Department of Public
Health and Environment. Land development projects ranging from 25 to 1,850
acres in size require permitting through the APCD and the implementation of
fugitive dust controls. Projects exceeding 1,850 acres will be subject to a
construction permit and public notice proceedings. Small land development
activities that are less than 25 contiguous acres and less than 6 months in duration
are exempt from permitting and do not need to report air emissions to the APCD,
but must use appropriate control treasures to minimize the release of fugitive dust
from the site.
This Fugitive Dust Control Plan addresses how dust will be kept to a minimum on
all applicable sites in Piceance.
This plan focuses action on:
1.0 General Operating Conditions
2.0 Control Measures for Unpaved Roadways and Disturbed Areas
3.0 Rccordkeeping and Permit Registration
4.0 Contingency Planning
1.0 General Operating Conditions
Field personnel and contractors are required to limit fugitive particulate matter
(fugitive dust) from all specific sources by taking the following steps:
• Fugitive dust from all activities, on -site haul roads, and haul trucks operating on
Chevron property must not result in off - property transport of visible emissions
• Fugitive dust on off -site haul roads must not interfere with or cause an
inconvenience on public or private property
• Fugitive dust from material in haul trucks must not result in visible emissions
when operating off -site of Chevron property
2.0 Control Measures for Unpaved Roadways and Disturbed Areas
Construction or maintenance work of any unpaved roadway may cause fugitive
dust emissions. Wind erosion of disturbed areas, including new roads, well pads,
parking and staging areas, and materials storage areas that have been cleared of
vegetation, leveled, or excavated, can also be a major source of fugitive dust
emissions. The following mitigation methods and controls are required to
minimize these emissions:
• All unpaved roads and disturbed surface areas on site shall be watered as
necessary to prevent off - property transport of visible fugitive particulate emissions
• Vehicle speeds on all unpaved roads and disturbed areas on the project site shall
not exceed a maximum of 30 miles per hour. Speed limit signs must be posted
along these roads.
• Land clearing, grading, carthmoving, and excavation activities must be
suspended when wind speeds exceed a velocity of 30 miles per hour
• All disturbed surface areas shall be rcvegetated within one year and completed
according to the information submitted in the permit application
• Gravel entryways shall be utilized to prevent mud and dirt carryover onto paved
surfaces. Any mud and dirt carryout onto paved surfaces shall be cleaned up
daily.
Other control measures that are recommended at the site but not required include:
• Compacting foundation soil on a daily basis to within 90% of maximum
compaction
• Installing silt fencing prior to earthmoving activities along property borders that
are adjacent to developed areas
3.0 Recordkeeping and Permit Registration
All records of current approved fugitive dust permits, Air Pollutant Emission
Notices, and approval letters from the APCD shall be kept and maintained on site.
Chevron must receive approval from the APCD prior to commencement of a new
land development project. Conditional approval for a fugitive dust general permit
is effective from the date the complete registration request is received by the
APCD.
A modified permit registration must be submitted to the APCD when:
• An increase in project size will result in greater emissions
• An increase in the duration of the project will result in fugitive particulates being
released longer than initially reported
• An increase in the amount of paving will occur on the site
• A decrease in dust control measures will be implemented from those initially
reported
4.0 Contingency Planning
Alternative control measures may become necessary in the event that the current
dust control strategy is not adequate or effective for conditions. An alternative
plan may require additional planning, permitting, or other regulatory compliance
requirements be implemented. When an alternative plan is needed, the current
activities at the project site must be suspended until such time as the alternate dust
control methods are put into place. These methods may include:
• Provide field personnel and contractors with contact information for responsible
individuals in cases where control measures need to he escalated in response to
weather conditions (i.c. shut down of operations due to increase in wind speed)
• Use an appropriate alternative dust inhibitor if water does not prove to be
effective, and obtain all regulatory permissions for the use of chemical
suppressants on the project site
• Use vegetative blankets or other methods for cover of topsoil, spoil, and bulk
material storage piles if immediate cover becomes necessary
• Attempt to locate alternative sources of bulk material closer to the project site if
fugitive dust emissions or other impacts from contract haul trucks on state or
federal highways become an issue with public safety or regulatory compliance
