The goal for erosion and sediment control at sites disturbed by construction is achievement of at least the minimum site rating to be in compliance with the city design criteria manual.
(1) 
All operators of construction sites shall use best management practices (BMPs) to control and reduce the discharge, to the MS4 and to waters of the United States, of sediment, silt, earth, soil, and other material associated with demolition, clearing, grading, excavation, land filling, and other construction activities to the maximum extent practicable. Any best management practices capable of installation and/or implementation prior to commencement of construction (for example, structural measures) shall be installed and/or implemented prior to commencement of construction at the site or in compliance with a schedule for installation and/or implementation in an applicable SWPPP. Permanent BMPs as required for post-construction water quality maintenance by the NPDES or TPDES construction general permit or other ordinances may be used during construction, as appropriate, for sediment and other pollutant control. They shall be restored to serve their post-construction function before development or redevelopment activities are completed.
(2) 
All sites shall comply with the requirements in any and all applicable current NPDES and TPDES storm water permits, when appropriate based upon the acreage of the construction site.
(Ordinance 1304, sec. 8-2.11, adopted 4/12/2010)
(a) 
Sites disturbing less than one acre or within a common plan of development that is disturbing less than one acre do not have to apply for state coverage, inspect the site, nor create plans. If general construction requirements are repeatedly not met, the owner/operator may be directed by the city to comply with some or all requirements for larger sites.
(b) 
Sites disturbing more than one acre of land or within a common plan of development that is disturbing more than acre of land shall comply with all sections of this article.
(1) 
The owner or operator shall ensure that copies of the notice of intent (NOI), notice of change (NOC), notice of termination (NOT), and construction site notice (CSN) are provided to the city when appropriate.
(c) 
Inspections.
(1) 
All construction sites shall be inspected per the TPDES construction general permit.
(2) 
All owners or operators of a construction site must provide an electronic version of inspection documentation at the frequency indicated by the construction general permit. Documentation will be of the condition of the practices and will note any repairs needed and action taken.
(3) 
Upon written notice by an agent of the city to the applicant or the applicant's designated representative regarding an erosion control action or repair needed to bring the site into compliance, the owner or operator shall comply with noted actions or repairs, and record such actions within 48 hours of the notification and prior to the next rain event. Failure to record such actions within 72 hours of notification shall be a violation of this article.
(d) 
Control measures.
Erosion and sediment control measures shall be designed and established at the site in a manner that minimizes erosion and retains sediment on-site to the maximum extent practicable with consideration of the topography, soil type, and rainfall. BMPs and control measures described in the Integrated Storm Management (iSWM) manual produced by the North Central Texas Council of Governments or subsequent versions are minimal control measures approved for use in the city. BMPs not listed in the iSWM manual may be considered and must receive city approval.
(e) 
Preserve existing vegetation.
The owner or operator shall ensure that existing vegetation is preserved to the maximum extent practicable. Should the existing vegetation not be preserved, the owner or operator shall take steps necessary to stabilize the site in order to prevent erosion.
(f) 
Maintenance.
(1) 
All temporary stabilization measures shall be maintained until final stabilization is established and a NOT is filed with the TCEQ, when required by the construction general permit, and the finalization of a city termination inspection has been conducted, or transfer of operational control has been completed, as required by the construction general permit, when appropriate based on the acreage of the construction site.
(2) 
The owner or operator of any site shall perform maintenance as necessary to maintain the continued effectiveness of storm water controls within 48 hours of discovery of failure, damage, or compromise and prior to the next rain event.
(3) 
Failure to maintain BMPs in proper working order shall be a violation of this article.
(4) 
Sediment or silt accumulation.
Should the control measures at a site fail, in part or in total, the owner or operator shall remove all sediment and siltation accumulation caused by BMP failure from the city's MS4, including streets and rights-of-way, within 48 hours of discovery or prior to the next rain event. Removal includes sweeping streets, sidewalks, and other infrastructure and removing sediment from the MS4.
(g) 
Waste.
(1) 
Proper waste disposal and waste management techniques shall be implemented, including covering waste materials, minimizing ground contact with regulated or hazardous chemicals and trash, and keeping trash receptacles off of paved surfaces or other locations that drain directly to a storm drain system or local waterway.
(2) 
This subsection also includes sanitary waste.
(h) 
Dust suppression.
Techniques shall be employed to prevent airborne dust from leaving the site.
(i) 
Concrete wash-out.
An operator shall specify a containment area and/or a concrete wash-out device that will be established and maintained for all sites. This designated area must be clearly marked with signs.
(Ordinance 1304, sec. 8-2.12, adopted 4/12/2010)
It is a violation of this article for any person to damage or allow be damaged any temporary or permanent storm water control measures through their actions or inactions without promptly restoring the control measures to an effective and efficient state.
(Ordinance 1304, sec. 8-2.13, adopted 4/12/2010)
(a) 
No contractor or sub-contractor shall commence work on a site without first attending training on storm water impacts from construction activities and maintenance of control measures.
(1) 
Location and availability of training shall be provided by the city.
(2) 
Prior training or training provided by another entity shall be considered by city staff. Staff shall consider the merits of said alternative training and may disapprove of this training for any reason.
(b) 
Contractors shall have proof of attendance available for inspection at any site. The contractor shall be responsible for ensuring that each of its employees is knowledgeable of the conditions of this article.
(Ordinance 1304, sec. 8-2.14, adopted 4/12/2010)
An erosion and sediment control plan shall be submitted to the city and reviewed and released by the city prior to the commencement of any activity on a site. Commencement of activity before the submittal, review and release of an erosion and sediment control plan shall be a violation of this article.
(Ordinance 1304, sec. 8-2.15, adopted 4/12/2010)
