If the control measures used result in ponding, the land application shall be done in an area with a constructed containment, such as an excavation or berm area with no outfall. The constructed containment shall prevent the discharge of the ponding water offsite as runoff.
6.A visible sheen is not evident in the discharge.
7.Control measures are implemented to prevent any sediment deposited during land application from being transported by stormwater runoff to surface waters or other conveyances.
8.All control measures used shall be selected, installed, implemented, and maintained according to good engineering, hydrologic , and pollution control practices. The selected control measures shall provide control for all potential pollutant sources associated with the discharge of uncontaminated groundwater to land. The discharge shall be routed in such a way that it will not cause erosion to land surface. Energy dissipation devices designed to protect downstream areas from erosion by reducing the velocity of flow (such as hose attachments, sediment and erosion controls) shall be used when necessary to prevent erosion. All dewatering operations shall be recorded in the SWMP as follows:
1.The source is identified in the SWMP and updated by the SWMP Administrator.
2.The SWMP describes and locates the practices implemented at the site to control stormwater pollution from the dewatering of groundwater or stormwater.
3.The SWMP describes and locates the practices to be used that will ensure that no groundwater from construction dewatering is discharged from the LOC as surface runoff or to surface waters or storm sewer s.
4.Groundwater and groundwater combined with stormwater do not contain pollutants in concentrations exceeding the State groundwater standards in Regulations 5 CCR 1002 - 41 and 42. If surface waters are diverted around a construction area and no pollutants are introduced during the diversion, a CDW Permit is not required. If the diverted water enters the construction area and contacts pollutant sources ( e.g., disturbed soil, concrete washout, etc.), the Contractor shall obtain a CDW permit for the discharge of this water to State waters or to the ground.
8.At least 15 days before commencing dredging or fill operations in a watercourse, the Contractor shall provide written notification to owners or operators of domestic or public water supply intakes or diversion facilities, if these facilities are within 20 miles downstream from t he dredging or fill operations. Notification shall also be given to 107.25 107-19 Owners or operators of other intakes or diversions that are located within five miles downstream from the site of the project. Identities of downstream owners and operators can be obtained from Colorado Division of Water Resources, Office of the State Engineer.
9.Temporary fill into wetlands or streams will not be allowed, except as specified in the Contract and permits. If such work is allowed, upon completion of the work all temporary fills shall be removed in their entirety and disposed of in an upland location outside of flood plains unless otherwise specified in the Contract.
10.Construction operations in waters of the United States as defined in 33 CFR Part 328.3, including wetlands, shall be restricted to areas and activities authorized by the U.S. Army Corps of Engineers as shown in the Contract. Fording waters will be allowed only as authorized by the U.S. Army Corps of Engineers 404 Permit.
11.Wetland areas outside of the permitted limits of disturbance shall not be used for storage, parking, waste disposal, access, borrow material, or any other construction support activity.
12.Pollutant byproducts of highway construction , such as concrete, asphalt, solids, sludges, pollutants removed in the course of treatment of wastewater, excavation or excess fill material, and material from sediment traps shall be handled, stockpiled , and disposed of in a manner that prevents entry into State waters , including wetlands. Removal of concrete waste and washout water from mixer trucks, concrete finishing tools, concrete saw, and all concrete material removed in the course of construction operations or cleaning shall be performed in a manner that prevents waste material from entering State waters and shall not leave the site as surface runoff. A minimum of 10 days before the start of the construction activity, the Contractor shall submit in writing a Method Statement for Containing Pollutant Byproducts to the Engineer for approval. The use of chemicals such as soil stabilizers, dust palliatives, herbicides, growth inhibitors, fertilizers, deicing salts, etc., shall be per the manufacturer’s recommended application rates, frequency, and instructions.
13.All materials stored on ‑site shall be stored in a neat, orderly manner, in their original containers, with the original manufacturer’s label. Materials shall not be stored in a location where they may be carried into State waters at any time.
14.Spill prevention and containment measures conforming to subsection 208.06 shall be used at storage, and equipment fueling and servicing areas to prevent the pollution of any State waters, including wetlands. All spills shall be cleaned up immediately after discovery or contained until appropriate cleanup methods can be employed. Manufacturer’s recommended methods for spill cleanup shall be followed, along with proper disposal methods. When required by the Colorado Water Quality Control Act, Regulation 5 CCR 1002 -61, spills shall be reported to the Engineer and CDPHE in writing.
15.The Contractor shall prevent construction activities from causing grass or brush fires.
16.The construction activities shall not impair Indian tribal rights, including, but not limited to, water rights, and treaty fishing and hunting rights.
17.Before start of work, the Contractor shall certify in writing to the Engineer that construction equipment has been cleaned before initial site arrival. Vehicles and equipment shall be free of soil and debris capable of transporting noxious weed seeds or invasive species onto the site. Additional equipment required for construction shall also be certified before being brought onto the project site. 107.25 107-20 18. Vehicles that have been certified by the Contractor as having been cleaned before arrival on site may be cleaned on site at an approved area where wash water can be properly contained. Vehicles leaving and reentering the project site shall be recertified.
19.At the end of each day, the Contractor shall collect all trash and dispose of it in appropriate containers.
20.Construction waste that is considered a pollutant or contaminant shall be collected and disposed of in appropriate containers. This material may be stockpiled on the project when it is contained or protected by an appropriate control measure.
21.If the project area is covered by a CDPS -SCP, permittees are authorized to discharge stormwater associated with construction activity and specified non -stormwater associated with construction activity to State waters.
A.Allowable Stormwater Discharges:
1.Stormwater discharges associated with construction activity.
2.Stormwater discharges associated with producing earthen materials, such as soils, sand, and gravel dedicated to providing material to a single contiguous site, or within 1/4 mile of a construction site ( i.e., borrow or fill areas).
3.Stormwater discharges associated with dedicated asphalt, concrete batch plants and masonry mixing stations. (Coverage under the CDPS -SCP is not required if alternative coverage has been obtained.)
4.Discharges resulting from emergency firefighting activities.
B.Allowable Non -Stormwater Discharges if identified in the SWMP with appropriate control measures:
1.Discharges from uncontaminated springs that do not originate from an area of land disturbance.
2.Discharges to the ground of concrete washout water associated with the washing of concrete tools and concrete mixer chutes. Discharges of concrete washout water shall not leave the site as surface runoff or reach receiving waters.
3.Discharges of landscape irrigation return flow. Discharges authorized by the CDPS -SCP shall not cause, have the reasonable potential to cause, or measurably contribute to an exceedance of any applicable water quality standard, including narrative standards for water quality. All construction site wastes shall be properly managed to prevent potential pollution of State waters. The CDPS -SCP does not authorize on -site waste disposal.
c.Stormwater Construction Permit . A Colorado Discharge Permit System Stormwater Construction Permit (CDPS -SCP) will be obtained from CDPHE by CDOT. The Contractor and CDOT will be co -permittees. The Contractor shall coordinate with CDOT to become 107.25 107-21 the Operator permittee of the respective permit upon award of the Contract. The Contractor shall provide a copy of permit certification as the Operator to the Engineer before or at the Pre -construction Conference. No work shall begin until the CDPS -SCP permit with Owner and Operator has been approved by CDPHE. A copy of the permit shall be placed in the project SWMP. The Contractor is legally required to obtain all other permits associated with specific activities within or outside of the right of way, such as borrow pits, concrete or asphalt plant sites, waste disposal sites, or other facilities. Staging areas within a quarter mile, but not within CDOT right of way shall be considered a common plan of development and permits for these facilities require permitting in the Contractor’s name as Owner and Operator. These permits include local agency, federal, or other stormwater permits. The Contractor shall consult with the Engineer and contact the CDPHE or other appropriate federal, state, or local agency to determine the need for any permit. When a Utility Company has obtained a CDPS -SCP within a CDOT project area, before the Contractor being on- site, the Contractor shall coordinate with the Engineer and the Utility Company to transfer or reassign the permit area within the project’s Limits of Construction to the Contractor and CDOT before work commencing. The Contractor shall not commence construction until CDPHE issues a new CDPS -SCP identifying the Contractor as the Operator, and the permit is put in the SWMP. To initiate acceptance of the stormwater construction work (including seeding and planting required for erosion control), the Contractor shall request in writing a Stormwater Completion Walkthrough. The Engineer will set up the walkthrough. It will include the Engineer or designated representative, Superintendent or designated representative, Stormwater Management Plan (SWMP) Administrator, Region Water Pollution Control Manager (RWPCM), Landscape Architect, and a Regional Maintenance representative. Unsatisfactory and incomplete stormwater and sediment/erosion control work will be identified in this walkthrough and will be summarized by the Engineer in a punch list. The completed action items associated with the corrective work will be shown as completed on the punch list. Upon completion of all items shown, the Contractor shall notify the Engineer. Upon written agreement that the punch list is completed from the Engi neer, the Contractor shall submit the appropriate form to the CDPHE such that CDOT Maintenance becomes the Operator permittee of the CDPS -SCP. Until the transfer of the permit has been approved by the CDPHE, the Contractor shall continue to adhere to all permit requirements. Requirements shall include erosion control inspections, control measure installation, control measure maintenance, control measure repair including seeded areas, and temporary control measure removal . All documentation shall be submitted to the Engineer and placed in the SWMP. All costs associated with the Contractor applying for, holding, and transferring the CDPS -SCP permit between parties will not be measured and paid for separately, but shall be included in the work per subsection 107.02.
d.Measurement and Payment.
1.All the work listed in (b) above, including but not limited to dewatering , erosion control for dewatering, and disposal of water resulting from dewatering operations, including all costs for CDPHE concurrences and permits, will not be measured and paid for separately, but shall be included in the work.
2.The Contractor shall be liable for any penalty (including monetary fines) applied to the Department caused by the Contractor’s noncompliance with any water quality permit or 107.25 107-22 certification. Monetary fines shall be deducted from any money due to the Contractor. If the monetary fine is in excess of all the money due to the Contractor, then the Contractor shall pay to the Department the amount of such excess.
3.The Contractor will not receive additional compensation, or time extensions, for any disruption of work or loss of time caused by any actions brought against the Contractor for failure to comply with good Engineering, hydrologic and pollution control pract ices.
4.If a spill occurs as a direct result of the Contractor’s actions or negligence, the cleanup of such spill shall be performed by the Contractor at the Contractor’s expense.
5.Areas exposed to erosion by fire resulting from the Contractor’s operations shall be stabilized per Section 208 by the Contractor and at the Contractor’s expense. 108.01 108-1 SECTION 108 PROSECUTION AND PROGRESS
108.01 Subletting of Contract. The Contractor shall not sublet, sell, transfer, assign, or
dispose of the Contract or Contracts, or any portion thereof without written permission of the Engineer. Before beginning any work by the subcontractor, the Contractor shall request permission from the Engineer by submitting a completed Sublet Permit Application, CDOT Form. 205, via the B2GNow software system. The subcontracted work shall not begin until the Contra ctor has received the Engineer’s written permission. The Contractor shall make all project -related written subcontracts, agreements, and purchase orders available to the Engineer for viewing, upon request, and at a location convenient to the Engineer. The Contractor will be permitted to sublet a portion of the Contract. However, the Contractor’s organization shall perform work amounting to 30 percent or more of the total original contract amount. Any items designated in the Contract as “specialty items” may be performed by subcontract. The cost of “specialty items” so performed by subcontract may be deducted from the total original contract amount before computing the amount of work required to be performed by the Contractor’s own organization. The original contract amount includes the cost of material and manufactured products that are to be purchased or produced by the Contractor and the actual agreement amounts between the Contractor and a subcontractor. The proportional value of a subcontracted partial contract item will be verified by the Engineer. When a firm both sells material to a prime contractor and performs the work of incorporating the materials into the project, these two phases shall be considered in combination and as constituting a single subcontract. The calculation of the percentage of subcontracted work shall be based on subcontract unit prices. Subcontracts or transfer of Contract shall not release the Contractor of liability under the Contract and Bond. Failure to comply with all contractual obligations may lead to the suspension, debarment, or both of the subcontractor, and if necessary, the Contractor as stipulated in the “Rules”. All firms that the contractor will be subletting a portion of the contract shall have an account created in the B2GNow software system. If the firm does not have an account created approval of the form 205 may be withheld.
108.02 Notice to Proceed . The Contractor shall not commence work before the issuance of a
Notice to Proceed. The “Notice to Proceed” will stipulate the date that contract time commences. When the Contractor proceeds with work before that date, contract time will commence on the date work actually begins. The Contractor shall commence work under the Contract on or before the 15th day following Contract execution or the 30th day following the date of award, whichever comes later , or per the selected start date allowed in the special provisions.
108.03 Project Schedule .
a.Definitions. Activity (Task). A portion of the project that requires time or resources to complete. An activity has a description, start date, finish date, duration, and one or more logic ties. A critical activity is an activity on the critical path.
