29MM4.1 -6 As required by South Coast Air Quality Management
District Rule 403 — Fugitive Dust, all construction activities that are
capable of generating fugitive dust are required to implement dust
control measures during each phase of project development to
reduce the amount of particulate matter entrained in the ambient
air. These measures include the following:
• Application of soil stabilizers to inactive construction areas
• Quick replacement of ground cover in disturbed areas
• Watering of exposed surfaces three times daily
• Watering of all unpaved haul roads three times daily
• Covering all stock piles with tarp
• Reduction of vehicle speed on unpaved roads
• Post signs on -site limiting traffic to 15 miles per hour or
less
• Sweep streets adjacent to the project site at the end of the
day if visible soil material is carried over to adjacent roads
• Cover or have water applied to the exposed surface of all
trucks hauling dirt, sand, soil, or other loose materials
before leaving the site to prevent dust from impacting the
surrounding areas
• Install wheel washers where vehicles enter and exit
unpaved roads onto paved roads to wash off trucks and
any equipment leaving the site for each trip
MM4.1 -7 The developer must require by contract specifications
that construction - related equipment, including heavy -duty
equipment, motor vehicles, and portable equipment, be turned off
when not in use for more than 30 minutes. Diesel- fueled
commercial motor vehicles with gross vehicular weight ratings of
greater than 10,000 pounds must be turned off when not in use for
more than 5 minutes. Contract specifications must be included in
the proposed project construction documents, which must be
approved by the City of El Segundo before grading permits are
issued.
MM4.1 -8 The developer must require by contract specifications
that construction parking be configured to minimize traffic
interference during the construction period and, therefore, reduce
idling of traffic. Contract specifications must be included in the
proposed project construction documents, which must be
approved by the City of El Segundo before grading permits are
issued.
MM4.1 -9 The developer must require by contract specifications
that temporary traffic controls are provided, such as a flag person,
during all phases of construction to facilitate smooth traffic flow.
