(Ordinance 12-03 adopted 4/19/12)
(a) Federal and state regulations.
Current Federal Regulations
(section 402 of the Clean Water Act) and state regulations (chapter
26 of the Texas Water Code) require all owners/operators of stormwater
discharges from industrial activities to apply for and operate pursuant
to Texas Pollutant Discharge Elimination System (TPDES) general permit
TXR150000 hereafter referred to as the “state permit.”
The state permit regulates land-disturbing activities that result
in the disturbance of one or more acres of total land area, including
areas smaller than one acre that are part of a larger common plan
of development or sale.
(b) A responsible party engaging in a regulated land-disturbing activity
is responsible for compliance with the Texas Commission on Environmental
Quality (TCEQ) state permit. The responsible party shall submit to
TCEQ a notice of intent (NOI) or construction site notice for coverage
under the state permit, and shall also provide the director of public
works with a copy of the NOI or construction site notice prior to
beginning any land-disturbing activity.
(c) A responsible party engaging in a regulated land-disturbing activity
shall prepare a stormwater pollution prevention plan (SWPPP) satisfying
all requirements of the state permit. A copy of the SWPPP shall be
provided to the director of public works prior to the start of any
land-disturbing activity. The SWPPP shall be prepared by either a
registered professional engineer licensed in the state, a certified
professional in erosion and sediment control (CPESC) or a certified
professional in stormwater quality (CPSWQ).
(d) Any responsible party not in compliance with the TPDES general permit
TXR150000 shall be in violation of this article as well as state and
federal law and shall be subject to all local, state and federal enforcements.
(Ordinance 12-03 adopted 4/19/12)
(a) Application of article.
A responsible party engaging
in any land-disturbing activity shall prepare an erosion control plan
and submit that plan to the city for approval. This article shall
apply regardless of whether a responsible party is required to obtain
a permit from the city in order to conduct such land-disturbing or
construction activity. The responsible party shall also be held liable
for violations of this article committed by third parties engaging
in activities related to the responsible party’s project.
(b) Erosion control plan implementation and compliance.
Each responsible party shall implement and maintain the erosion control
measures shown on its approved erosion control plan in order to minimize
the erosion and the transport of silt, earth, topsoil, etc., by water
run off or construction activities, beyond the limits of the responsible
party’s site onto city streets, drainage easements, drainage
facilities, storm drains or other city property prior to beginning
any land-disturbing activity.
(c) Off-site borrow, spoil and staging areas.
Where applicable,
off-site borrow areas, spoil areas and construction staging areas
shall be considered as part of the project site and shall be governed
by this article.
(d) Related land areas.
The erosion control requirements
of this article shall apply to all related land areas. Additionally,
when land-disturbing activity occurs on a project, all disturbed land
areas related to the project shall have permanent erosion control
established before final occupancy of structures located thereon or
final acceptance of the subdivision may be obtained. This section
applies whether or not a building permit is required.
(e) Belowground installations.
All discharges resulting
from belowground installations shall be passed through city-approved
erosion control device(s) or removed from the site and properly disposed
of.
(Ordinance 12-03 adopted 4/19/12)
Plan requirements generally. Each erosion
control plan required by this article shall clearly identify all erosion
and sediment control measures to be installed and maintained throughout
the duration of the project for which that plan is submitted. The
responsible party shall install and maintain erosion control devices
in accordance with their city-approved erosion control plan as required
by this article. Erosion and sediment control devices shall be installed
and maintained in accordance with the city’s erosion control
manual. General guidelines for erosion and sediment control are as
follows:
(1) Maximum use shall be made of vegetation to minimize soil loss.
(2) Natural vegetation should be retained wherever possible.
(3) Where inadequate natural vegetation exists, or where it becomes necessary
to remove existing natural vegetation, temporary controls should be
installed promptly to minimize soil loss and ensure that erosion and
sedimentation does not occur.
(4) Wherever possible during construction, erosion and sedimentation
controls shall be used on hillsides to slow drainage flow rate.
(5) Erosion and sedimentation control elements should be implemented
as soon as practical in the development process. Erosion and sedimentation
controls shall be maintained by the responsible party. Erosion and
sedimentation controls that are installed but not properly maintained
in accordance with the city’s erosion control manual shall be
considered a violation of this article.
(6) Waste or disposal areas and construction roads should be located
and constructed in a manner that will minimize the amount of sediment
entering streams.
(7) Frequent fording of live streams will not be permitted; therefore,
temporary bridges or other structures shall be used wherever an appreciable
number of stream crossings are necessary.
(8) When work areas or material sources are located in or adjacent to
live streams, such areas shall be separated from the stream by a dike
or other barrier to keep sediment from entering a flowing stream.
Care shall be taken during the construction and removal of such barriers
to minimize the sediment transport into a stream.
(9) Should preventative measures fail to function effectively, the applicant
shall act immediately to bring the erosion and/or siltation under
control by whatever additional means are necessary.
(10) Erosion control devices shall be placed to trap any losses from stockpiled
topsoil.
(11) The selection and timing of the installation of erosion controls
shall be based upon weather and seasonal conditions that could make
certain controls not practicable.
(12) Vegetation used for vegetative cover shall be suitable for local
soil and weather conditions. Ground cover plants shall comply with
listings from the Texas Agricultural Extension Service for North Central
Texas.
(13) Runoff shall be diverted away from construction areas as much as
possible.
(14) Stripping of vegetation from project sites shall be phased so as
to expose the minimum amount of area to soil erosion for the shortest
possible period of time. Phasing shall also consider the varying requirements
of an erosion control plan at different stages of construction.
(15) Developers, builders, or owners of property shall install all utilities,
including franchise utilities, before final acceptance of a subdivision,
property and/or structure. Final acceptance will also be contingent
upon having all necessary erosion control measures installed to minimize
off-site sediment. A site may be accepted without erosion control
measures if perennial vegetative cover is actively growing at the
discretion of the director of public works.
(Ordinance 12-03 adopted 4/19/12)
(a) Prior to beginning any land-disturbing activity or upon the effective
date of this article, a responsible party engaging in land-disturbing
activity for nonresidential and multifamily construction projects
