104.07 Permitting Requirements

There are a number of permits that will need to be received prior to the start of construction. The Forest Service will submit the applications for these permits.

• The San Diego Water Quality Control Board will need to issue a Section 401 Water Quality Certification. They will also be issuing a Construction Activities Storm Water General Permit. The application for the Storm Water Permit requires submittal of a Storm Water Pollution Prevention Plan (SWPPP). It is the Contractor’s responsibility to prepare the SWPPP in accordance with Section 157

– Soil Erosion Control.

• The US Army Corps of Engineers will issue a Section 404 permit.

• The California Department of Fish and Wildlife will be issuing a Streambed

Alteration Agreement. The application for this permit requires submittal of the Dewater Plan. It is the Contractor’s responsibility to prepare the Dewater Plan in accordance with Sections 157 – Soil Erosion Control and 648 – Stream Simulation.

106 - Acceptance of Work 106.01_nat_us_03_29_2005

106.01 Conformity with Contract Requirements.

Delete Subsection 106.01 and substitute the following:

Follow the requirements of FAR Clause 52.246-12 Inspection of Construction.

References to standard test methods of AASHTO, ASTM, GSA, and other recognized standard authorities refer to the methods in effect on the date of solicitation for bids.

Perform all work to the lines, grades, cross-sections, dimensions, and processes or material requirements shown on the plans or specified in the contract.

Incorporate manufactured materials into the work according to the manufacturer’s recommendations or to these specifications, whichever is more strict.

Plan dimensions and contract specification values are the values to be strived for and complied with as the design values from which any deviations are allowed. Perform work and provide material that is uniform in character and reasonably close to the prescribed value or within the specified tolerance range. The purpose of a tolerance range is to accommodate occasional minor variations from the median zone that are unavoidable for practical reasons.

When standard manufactured items are specified (such as fence, wire, plates, rolled shapes, pipe conduits, etc., that are identified by gauge, unit mass, section dimensions, etc.), the identification will be considered to be nominal masses or dimensions. Unless specific contract tolerances are noted, established manufacturing tolerances will be accepted.

The Government may inspect, sample, or test all work at any time before final acceptance of the project. When the Government tests work, copies of test reports are furnished to the Contractor upon request. Government tests may or may not be performed at the work site. If Contractor testing and inspection is verified by the Government, the Contractor’s results may be used by the Government to evaluate work for acceptance.

Do not rely on the availability of Government test results for process control.

Acceptable work conforming to the contract will be paid for at the contract unit bid price.

Four methods of determining conformity and accepting work are described in Subsections

106.02 to 106.05 inclusive. The primary method of acceptance is specified in each Section of work. However, work may be rejected at any time it is found by any of the methods not to comply with the contract.

Remove and replace work that does not conform to the contract, or to prevailing industry standards where no specific contract requirements are noted, at no cost to the Government.

(a) Disputing Government test results. If the accuracy of Government test results is disputed, promptly inform the CO. If the dispute is unresolved after reasonable steps are taken to resolve the dispute, further evaluation may be obtained by written request. Include a narrative describing the dispute and a proposed resolution protocol that addresses the following:

(1) Sampling method;

(2) Number of samples;

(3) Sample transport;

(4) Test procedures;

(5) Testing laboratories;

(6) Reporting;

(7) Estimated time and costs; and

(8) Validation process.

If the evaluation requires additional sampling or testing be performed, mutually agree with the Government on witnessing procedures and on sampling and testing by a third party laboratory. Use a third party laboratory accredited by the AASHTO accreditation program. Provide proof of the laboratory’s accreditation for the test procedures to be used. Do not use the same laboratory that produced the disputed Government test results or that produced the test results used as a basis for the dispute.

The CO will review the proposed resolution protocol and may modify it before final approval and execution.

The Government will use the approved resolution protocol test results to determine the validity of the disputed testing. If the Government test results are validated, the Contractor will be responsible for all costs associated with developing and performing the resolution protocol. If the Government test results are not validated, the Government will be responsible for all costs associated with developing and performing the resolution protocol. If the validity of the Government test results cannot be determined, the Contractor and Government will equally share all costs associated with developing and carrying out the resolution protocol.

(b) Alternatives to removing and replacing non-conforming work. As an alternative to removal and replacement, the Contractor may submit a written request to:

(1) Have the work accepted at a reduced price; or

(2) Be given permission to perform corrective measures to bring the work into conformity.

The request must contain supporting rationale and documentation. Include references or data justifying the proposal based on an evaluation of test results, effect on service life, value of material or work, quality, aesthetics, and other tangible engineering basis. The CO will determine disposition of the nonconforming work.

151 - Mobilization

151.01 Description

Add the following:

This work consists of washing and treating construction equipment and vehicles necessary for equipment transport to remove seeds, plants, and plant fragments before the equipment is used on Forest Service lands.

Wash the sides, tops, and undercarriages of all construction equipment. Remove all seeds, plants, plant fragments, dirt, and debris from the construction equipment. Only equipment inspected by the Forest Service will be allowed to operate within the project area. All subsequent move-ins of equipment to the project area will be treated in the same manner as the initial move-in. This requirement does not apply to cars, pickup trucks, and other vehicles that regularly travel between the construction site and areas off the National Forest.

Equipment will be considered free of soil, seed, and other such debris when a visual inspection does not disclose such material. Disassembly of equipment, components or the need for specialized inspection tools is not required.

Notify the CO in writing at least 48 hours before moving any construction equipment onto the national forest. Notification will include an agreed upon location where the equipment will be available for inspection by the Forest Service. Inspection will be required after every cleaning.

Use methods of cleaning and locations for cleaning approved by the C.O.

For work at a commercial washing facility, use an approved facility.

New infestations of noxious weeds of concern to Forest Service and identified by either Contractor or Forest Service, on the Project Area or on the haul route, will be promptly reported to the other party. Contractor and Forest Service will agree on treatment methods to reduce or stop the spread of noxious weeds when new infestations are found. A current list of noxious weeds of concern to Forest Service is available at each Forest Service office.

151.02 Measurement

Clean equipment prior to moving onto this project. The initial cleaning will not be included in the measurement for payment. Payment under this item will only be made if subsequent cleanings are ordered by the CO. Measurement shall be on an “each” basis, meaning one complete cleaning of all equipment required for this contract.

Subsequent cleanings necessitated by the Contractor’s actions but not directed by the CO will not be included in the measurement for payment.

152 - Construction Survey and Staking 152.00_nat_us_02_23_2005

Description

152.01(c) Material.

Mark all stakes with a stake pencil that leaves a legible imprint, or with waterproof ink.

Do not use aerosol spray paints.

Use moisture-resistant paper for survey notes. Keep notes in books with covers that will protect the contents and retain the pages in numerical sequence.

Construction Requirements

152.02 General.

Delete the first two sentences.

Add the following:

All construction staking for elevation control, grade control, site layout, bridge components and roadway shall be the responsibility of the Contractor. Contractor shall stake location of all bridge components for approval of the Contracting Officer prior to construction. The Contractor is responsible for maintaining the construction staking.

When indicated on the plans, a preliminary survey line has been established on the ground. The project location line is established by offsets from this preliminary line.

Delete second sentence in second paragraph and replace with the following:

Reestablish missing reference, control lines, or stakes as necessary to control subsequent construction staking operations

152.03 Survey and Staking Requirements.

(b) Roadway cross-sections.

Replace the first two sentences with the following:

Take roadway cross-sections normal to centerline. When the centerline curve radius is less than or equal to 200 feet, take cross-sections at a maximum centerline spacing of 25 feet. When the centerline curve radius is greater that 200 feet take cross-sections at a maximum centerline spacing of 80 feet.

c) Slope Stakes & References:

Replace section with the following:

Slope stakes and references. When required, locate slope stakes on designated portions of the road. Locate the slope stake catch points and use them to establish clearing limits and slope stake references.

Mark slope stakes with the station, the amount of cut or fill, the horizontal distance to centerline, and the slope ratios.

Place slope reference stakes at least 10 feet outside the clearing limit and mark with the offset distance to the slope stake. Place sight stakes when required.

Prior to clearing and grubbing operations, move the slope stake outside the clearing limit to the slope reference stake. After clearing and grubbing and before excavation, reset the slope stakes in their original position.

Use the designated method to establish the slope stake catchpoint.

• Method I—Computed Method. Use the template information shown in the plans or other Government-provided data to calculate the actual location of the catchpoint. The slope stake “catchpoint distance” provided may be used as a trial location to initiate slope staking. Recatch slope stakes on any section that does not match the staking report within the tolerances established in Table 152-2.

• Method II—Catchpoint Measurement Method. Determine the location of slope stake catchpoints by measuring the catchpoint distances shown in the plans or other Government-provided data.

(d) Clearing and grubbing limits.

Establish clearing limits on each side of the location line by measuring the required horizontal or slope distances shown in the stake notes. Mark the clearing limits with flagging or tags on trees to be left standing, or on lath. Make markings intervisible, and no more than 90 feet apart.

After establishing clearing limits, move the location line stake outside the clearing limits for station identification purposes, and mark it with horizontal distance to location line.

(e) Centerline reestablishment.

Replace with the following:

Reestablish centerline from instrument control points. The maximum spacing between centerline points is 25 feet when the centerline curve radius is less than or equal to 200 feet. When the centerline curve radius is greater than 200 feet, the maximum distance between centerline points is 80 feet.

(g) Culverts.

Replace subsection with the following:

Set culvert reference stakes at all culvert locations. Set a culvert reference stake on the centerline of the culvert 10 feet from each end or beyond the clearing limit, whichever is greater. Record the following on culvert reference stakes:

(1) Diameter, actual field measured length, and type of culvert.

(2) The vertical and horizontal distance from the reference stake to the invert at the ends of the culvert.

(3) Station of actual point where culvert intersects centerline.

When required, stake headwall for culverts by setting a hub with a guard stake on each side of the culvert on line with the face of the headwall. Perform this work after clearing is completed.

Contracting Officer or RWQCB, shall be performed until the Contracting Officer and RWQCB has approved the SWPPP.

C. The Contractor shall designate a Water Pollution Control Manager. The Water

Pollution Control Manager shall be responsible for the preparation of the SWPPP and any required modifications or amendments and shall be responsible for the implementation and adequate functioning of the various water pollution control practices employed. The Water Pollution Control Manager shall serve as the primary contact for all issues related to the SWPPP or its implementation, monitoring and maintenance. The Contractor shall submit to the Contracting Officer a statement of qualifications, describing the training, previous work history and expertise of the individual selected by the Contractor to serve as Water Pollution Control Manager. The Contracting Officer will reject the Contractor’s submission of a Water Pollution Control Manager if the submitted qualifications are deemed to be inadequate.

D. Within 30 days after the issuance of the Notice to Proceed on the contract, the

Contractor shall submit 5 copies of the SWPPP to the Contracting Officer.

E. The objectives of the SWPPP shall be to:

• Identify all pollutant sources including sources of sediment that may affect the quality of storm water discharges associated with construction activity (storm water discharges) from the construction site, and

• Identify non-storm water discharges, and

• Identify, construct and implement in accordance with a time schedule, and maintain BMPs to reduce or eliminate pollutants in storm water discharges from the site during the duration of the work.

• Develop a maintenance schedule for BMPs installed before and during construction designed to reduce or eliminate pollutants after construction is completed (post-construction BMPs).

The SWPPP shall apply to all areas that are directly related to construction activities and other site work including, but not limited to, staging areas, storage yards, and access roads within or outside of the Project limits.

F. As a minimum, the SWPPP shall incorporate pollution control practices in the following categories:

1. Soil Stabilization;

2. Sediment control;

3. Tracking control;

4. Wind erosion control;

5. Non-storm water control; and

6. Waste management and material pollution control.

7. Sampling and analysis

G. The Contractor shall develop a Water Pollution Control Schedule that shall describe the timing of grading or other work activities that could affect water pollution. The Water Pollution Control Schedule shall be updated by the Contractor to reflect any changes in the Contractor’s operations that would affect the necessary implementation of water pollution control practices.

H. The Contractor shall incorporate the “Minimum Requirements” presented in the Preparation Manual into the SWPPP. In addition to the “Minimum Requirements” presented in the Preparation Manual, the Contractor shall complete the BMP Consideration Checklist presented in the Preparation Manual and incorporate the appropriate BMPs into the SWPPP.

I. One hundred percent (100%) of exposed disturbed areas including all flat areas and slopes must have erosion protection BMPs properly installed and maintained during the rainy season (October 1 through April 30). Unpaved roadways and traveled ways within contractor’s onsite yards are exempt from 100% erosion control protection requirement but shall have, where appropriate, BMPs installed such as gravel bag chevrons as conditions warrant.

J. The Contractor shall prepare an amendment to the SWPPP when there is a change in construction activities or operations which may affect the discharge of pollutants to surface waters, ground waters, municipal storm drain systems, or when recommended by the Forest Service. Amendments shall show additional water pollution control practices or revised operations, including those areas or operations not shown in the initially approved SWPPP.

Amendments to the SWPPP shall be prepared and submitted for review and approval in the same manner as specified for the SWPPP approval.

Subsequent amendments shall be submitted within a time approved by the Contracting Officer, but in no case longer than the time specified for the initial submittal and review of the SWPPP. At a minimum, the SWPPP shall be amended annually and submitted to the Contracting Officer 25 days prior to the defined rainy season.

K. The Contractor shall keep one copy of the approved SWPPP and approved amendments at the project site. The SWPPP shall be made available upon request of a representative of the Regional Water Quality Control Board, State Water Resources Control Board, United States Environmental Protection Agency or the local storm water management agency. Requests by the public shall be directed to the Contracting Officer.

L. SWPPP IMPLEMENTATION

Upon approval of the SWPPP, the Contractor shall be responsible throughout the duration of the project for sampling and analysis (if required), installing, constructing, inspecting, maintaining, removing and disposing of the water pollution control practices included in the SWPPP and any amendments.

Implementation of the SWPPP begins when construction begins, and before initial clearing, grubbing, and grading operations. Unless otherwise directed by the Contracting Officer, the Contractor’s responsibility for SWPPP implementation shall continue throughout any temporary suspension of work ordered.

If the Contractor or the Contracting Officer identifies a deficiency in any aspect of the implementation of the approved SWPPP or amendments, the deficiency shall be corrected immediately. The deficiency may be corrected at a later date and time, if requested by the Contractor, and approved by the Contracting Officer in writing, but not later than the onset of the precipitation. If the Contractor fails to correct the identified deficiency by the date agreed or prior to the onset of precipitation the project shall be in noncompliance.

If the Contractor fails to conform to the provisions of “Water Pollution Control,” the Contracting Officer may order the suspension of any construction operations which create water pollution.

Implementation of water pollution control practices may vary by season. The Construction Site BMP Reference Manual and these special provisions shall be followed for control practice selection of year round, rainy season and non-rainy season water pollution control practices.

M. YEAR- ROUND IMPLEMENTATION REQUIREMENTS

1. The Contractor shall conduct sampling and analysis (if required), and have a year-round program for implementing, inspecting and maintaining water pollution control practices for soil stabilization, wind erosion control, tracking control, sediment control, non-storm water control, waste management and materials pollution control.

2. As part of the SWPPP, the Contractor’s shall have a “weather triggered” action plan and have the ability to deploy standby BMPs as needed to completely protect the exposed portion of the project site within 48 hours of a predicted storm event.

3. The National Weather Service weather forecast shall be monitored and used by the Contractor on a daily basis. An alternative weather forecast proposed by the Contractor may be used if approved by the Contracting Officer. If precipitation is predicted, the necessary water pollution control practices shall developed prior to the onset of the precipitation.

4. A minimum of 100% of the material needed to install weather triggered BMPs necessary to completely protect the exposed portions of the site from erosion, and to prevent sediment discharges, must be stored on site. Areas that have already been protected from erosion using physical stabilization or established vegetation stabilization BMPs as determined by the Contracting Officer, are not considered “exposed” for purposes of this requirement.

5. Disturbed soil areas shall be considered active whenever the soil disturbing activities have occurred, continues to occur or will occur during the ensuing 21 days. Non-active areas shall be protected as prescribed in the Construction Site BMP Manual within 14 days of cessation of soil disturbing activities or prior to the onset of precipitation, whichever occurs first.

6. In order to provide effective erosion control the Contractor may be requested to apply permanent erosion control in small or multiple units as disturbed soil areas are deemed substantially complete by the Contracting Officer.

7. The Contractor shall implement, maintain, and inspect the following temporary sediment control practices on a year-round basis, as conditions warrant. The listed practices shall remain in place until their use is no longer needed, as determined by the Contracting Officer.

8. The active disturbed soil area of the project site shall be not more than 1 acre.
