The purpose of this chapter is to establish minimum requirements
for construction and demolition activities and other specified sources
in order to reduce man-made fugitive dust and the corresponding PM10
emissions.
(Prior code § 150.115)
For the purpose of this chapter, the following definitions are
applicable:
“Agricultural operations”
means any operation directly related to the growing of crops,
or raising of fowls or animals for the primary purpose of making a
livelihood.
“AQMD”
means the South Coast Air Quality Management District and
the representatives thereof.
“Average daily traffic (ADT)”
is the number of motor vehicles that traverse a given unpaved
or paved surface during a specified 24-hour period. ADT levels are
calculated as the average daily volume over a specified 48-hour period
as determined by the City (County) in consultation with the AQMD.
“Bulk material”
means all sand, gravel, soil, aggregate and other organic
and inorganic particulate matter.
“Chemical dust suppressants”
means nontoxic chemical soil binders that are not prohibited
for use by the City (County), the California Regional Water Quality
Control Board, the California Air Resources Board, the U.S. Environmental
Protection Agency (U.S. EPA), or any other law, rule or regulation,
used to reduce dust on disturbed surfaces.
“Coachella Valley Fugitive Dust Control Handbook”
means the most recently approved reference document by the
AQMD that includes a description of fugitive dust control measures,
guidance for preparation of fugitive dust control plans, notification
forms, signage provisions, and test methods.
“Construction activities”
means any on-site activities preparatory to or related to
the building, alteration, rehabilitation, or improvement of property,
including, but not limited to the following activities: grading, excavation,
trenching, loading, vehicular travel, crushing, blasting, cutting,
planning, shaping, breaking, equipment staging/storage areas, weed
abatement activities or adding or removing bulk materials from storage
piles.
“Demolition activities”
means the wrecking or taking out of any load-supporting structural
member of a structure or building and related handling operations
or the intentional burning of any structure or building.
“Disturbed surface area”
means any portion of the earth’s surface (or material
placed thereupon) that has been physically moved, uncovered, destabilized,
or otherwise modified from its undisturbed native condition (including
vehicular disturbances) thereby increasing the potential for the emission
of fugitive dust. This definition does not include land that has been
restored to a native condition, such that the vegetative groundcover
and soil characteristics are equal to surrounding native conditions.
“Finish grade”
means the final grade of the site that conforms to the approved
grading plan.
“Fugitive dust”
means any solid particulate matter that becomes airborne,
other than that emitted from an exhaust stack, directly or indirectly
as a result of human activities. PM10 is a subset of fugitive dust
and is defined as particulate matter with an aerodynamic diameter
of ten microns or less.
“Fugitive dust control plan”
means a document that describes fugitive dust sources at
a site and the corresponding control measures and is prepared in accordance
with the guidance contained in the Coachella Valley Fugitive Dust
Control Handbook (2003).
“High-wind episode”
is when wind speeds exceed 25 miles per hour as measured
by:
1.
The closest AQMD monitoring station; or
2.
A certified meteorological monitoring station; or
3.
An on-site wind monitor calibrated and operated on-site in accordance
with the manufacturer’s specifications with a data logger or
strip chart.
“Operator”
means any person who owns, leases, operates, controls, or
supervises any potential fugitive dust generating operation subject
to the requirements of this chapter. This definition includes any
person who has been officially designated by a property owner as the
person responsible for fugitive dust control at a site, as indicated
in an approved fugitive dust control plan.
“Paved road”
means an improved street, highway, alley, public way, or
easement that is covered by roadway materials (e.g., cement, asphalt
or asphaltic concrete).
“Physical access restriction”
means any barrier, including but not limited to: curbs, fences,
gates, posts with fencing, shrubs, trees, or other measures that are
effective in preventing vehicular and off-highway vehicle (OHV) use
of a specified site.
“Silt”
means any bulk material with a particle size less than 75
micrometers in diameter that passes through a Number 200 sieve as
determined by American Society of Testing and Materials (ASTM) Test
Method C 136 or any other test method approved by the U.S. EPA and
AQMD.
“Site”
means the real property on which construction, demolition,
or other activities subject to this chapter may occur.
“Stabilized surface”
means any portion of land that meets the minimum standards
as established by the applicable test method contained in the Coachella
Valley Fugitive Dust Control Handbook (2003).
“Storage pile”
means any accumulation of bulk material with a height of
three feet or more and a total surface area of 300 or more square
feet.
“Unpaved parking lot”
means an area utilized for parking vehicles and associated
vehicle maneuvering that is not covered with roadway materials (e.g.,
cement, asphalt or asphaltic concrete).
“Unpaved road”
means any service roads, internal access roads, heavy and
light duty equipment paths and other roadways which are not covered
by typical roadway materials (e.g., cement, asphalt, asphaltic concrete).
(Prior code § 150.116)
All performance standards and test methods referenced in this
chapter shall be based on the methodologies included in the Coachella
Valley Fugitive Dust Control Handbook.
(Prior code § 150.117)
Violation of, or failure to comply with any provisions of an
approved fugitive dust control plan shall be a violation of this chapter.
(Prior code § 150.126)
