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 corresponding PM10 emissions.
(Ord. 1639 § 1, 2003)
For the purpose of this chapter, the following definitions are
applicable.
"Agricultural operations"
are any operation directly related to the growing of crops,
or raising of fowls or animals for the primary purpose of making a
livelihood.
"AQMD"
is 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 twenty-four-hour period. ADT levels
are calculated as the average daily volume over a specified forty-eight
hour period as determined by the city in consultation with the AQMD.
"Bulk material"
is all the sand, gravel, soil, aggregate and other organic
and inorganic particulate matter.
"Chemical dust suppressants"
are non-toxic chemical soil binders that are not prohibited
for use by the city, 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 regulations,
used to reduce dust on disturbed surfaces.
"City"
means the city of Palm Springs or its authorized representative.
"Coachella Valley Fugitive Dust Control Handbook"
is 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"
are 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"
is 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 ground cover
and soil characteristics are equal to surrounding native conditions.
"Finish grade"
is the final grade of the site that conforms to the approved
grading plan.
"Fugitive dust"
is 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"
is 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.
"High-wind episode"
is when wind speeds exceed twenty-five 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"
is 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"
is an improved street, highway, alley, public way, or easement
that is covered by a roadway materials (e.g., cement, asphalt or asphaltic
concrete).
"Physical access restriction"
is 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"
is any bulk material with a particle size less than seventy-five
micrometers in diameter that passes through a Number two hundred 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"
is the real property on which construction, demolition, or
other activities subject to this ordinance may occur.
"Stabilized surface"
is 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.
"Storage pile"
is any accumulation of bulk material with a height of three
feet or more and a total surface area of three hundred or more square
feet.
"Unpaved parking lot"
is 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"
is 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).
(Ord. 1639 § 1, 2003)
All performance standards and test methods referenced in this
ordinance shall be based on the methodologies included in the Coachella
Valley Dust Control Handbook.
