ARCHEOLOGICAL PROTECTION

SECTION 01 35 13.22

PART 1 - GENERAL

1.1 SUMMARY

A. The work of this section consists of protecting archeological resources contained in soil deposits.

1.2 DEFINITIONS

A. Archeological Resources: Archeological resources are the physical evidences of past human activity, including evidences of the effects of that activity on the environment. Archeological resources represent both prehistoric and historic time periods. They are found above and below ground and under water.

B. Archeologically Sensitive Areas: Areas that have the potential to contain significant

(National Register eligible) archeological resources. If National Register eligible or listed archeological resources could not be avoided, an appropriate mitigation strategy would be developed in consultation with the state historic preservation officer and, if necessary, associated American Indian tribes.

C. Non-sensitive Areas: Areas with little, if any, potential of containing significant (National

Register eligible) archeological resources.

D. Archeological Monitor: Representative of the Government designated to oversee construction activities that could disturb archeological resources.

E. Archeological Resources Protection Act (ARPA) of 1979 (P.L. 96-95; 93 Stat. 712): defines archeological resources as any material remains of past human life or activities that are of archeological interest and at least one hundred (100) years old; Section 4 of the statute describes the requirements that must be met before Federal authorities can issue a permit to excavate or remove any archeological resource on Federal or Indian lands; the curatorial requirements of artifacts, and other materials excavated or removed.

1.3 SUBMITTALS

A. Daily Work Schedule; Submit a Daily work Schedule detailing construction work in archeologically sensitive areas. Submit to Contracting Officer thirty (30) days before start of ground disturbing site work.

MORA – 157430 01 35 13.22 - 2

1.4 QUALITY ASSURANCE

A. At least one (1) week before on-site work begins, Contractor shall meet with Contracting Officer and Archeological Monitor to discuss Daily Work Schedule and equipment and special methods to be used in archeologically sensitive areas. Contractor shall ensure that approved Daily Work Schedule is followed throughout construction.

PART 2 – PRODUCTS

2.1 DAILY WORK SCHEDULE

A. A Daily Work Schedule is required for all work occurring within archeologically sensitive areas. Include all work that is to occur within the area and key the schedule to the drawings to include the following:

1. Starting and ending dates of ground-disturbing construction.

2. Locations of temporary facilities, such as barriers, field offices, staging areas, sanitary facilities, borrow pits, and haul and access roads.

3. Types of construction, such as clearing, topsoil stripping, structure or trench excavation, landscaping, and post construction clean-up.

4. Methods and equipment used for each type of construction.

5. Plan for relocating work in the event of temporary work stoppages at each archeologically sensitive area

PART 3 – EXECUTION

3.1 BARRICADES

A. Comply with requirements specified in Division 01 Section “Temporary Facilities & Controls.”

3.2 ARCHEOLOGICAL INVESTIGATION BY NON-NPS PERSONNEL

A. All archeological work will be undertaken by NPS personnel, if required.

3.3 OBSERVATION

A. Archeological Monitor will observe all ground-disturbing site work, including construction of temporary facilities, at all archeologically sensitive areas, from a safe location mutually agreed on by Contractor and Monitor. As new ground is broken, Monitor will examine excavated materials, using construction layout centerline and perimeter staking as a reference point to record locations of findings.

3.4 DISCOVERY OF RESOURCES

A. If Archeological Monitor discovers resources, immediate relocation of the work to a non-sensitive area may be required to allow Monitor to identify and document resources and, if necessary, develop an appropriate mitigation plan. While Archeological Monitor is

MORA – 157430 01 35 13.22 - 3

ARCHEOLOGICAL PROTECTION

documenting resources in sensitive areas, Contractor shall relocate work to non-sensitive areas where monitoring is not normally required.

B. If resources are discovered while Archeological Monitor is absent, stop work immediately and report the discovery to the Contracting Officer.

3.5 WORK STOPPAGE

A. The Contractor shall plan, schedule, and execute the work to prevent stoppages at one area from stopping all work at the construction site.

TEMPORARY STORM WATER

POLLUTION PREVENTION

SECTION 01 57 23

TEMPORARY STORM WATER POLLUTION PREVENTION

A. Federal Regulations for controlling discharges of pollutants (including chemicals, erodible material, and trash) from municipal separate storm sewer systems, construction sites, and industrial activities, were brought under the National Pollution Discharge Elimination System (NPDES) permit process by amendments to the Clean Water Act (CWA), and promulgation of federal stormwater regulations issued by the U.S. Environmental Protection Agency (USEPA). The USEPA uses the amount of ground disturbance as a measure of a project potential to generate pollution from erosion. NPDES Phase I regulates discharges from construction sites that disturb five (5) acres or more. NPDES Phase II regulations expand the existing General Permit requirements under Phase I to include/regulated discharges from construction sites that disturb land equal to or greater than one (1) acre and less than five (5) acres, known as Small Construction Activity. Construction disturbances one (1) acre and above typically require a formal NPDES permit and a formal Stormwater Pollution Prevention Plan (SWPPP) must be submitted to the Authority Having Jurisdiction (AHJ) for review and approval.

B. The work of this section consists of implementing measures to prevent discharges of pollutants, including temporary storm water pollution during construction activities, either through compliance with the NPDES permit program; Or in conformance with NPS guidance for UPPPs.

1.2 DEFINITIONS

A. Definitions pertaining to sustainable development: As defined in ASTM E2114.

B. Environmental Pollution and Damage: The presence of chemical, physical, or biological elements or agents which adversely affect human health or welfare; unfavorably alter ecological balances; or degrade the utility of the environment for aesthetic, cultural, or historical purposes.

C. National Pollution Discharge Elimination System (NPDES) Phase I: Regulates discharges from construction sites that disturb five (5) acres or more.

D. NPDES Phase II: Regulations expand the existing General Permit requirements under Phase I to include and regulate discharges from construction sites that disturb land equal to or greater than one (1) acre and less than five (5) acres, known as Small Construction Activity.

MORA – 157430 01 57 23 - 2

TEMPORARY STORM WATER

POLLUTION PREVENTION

E. Storm Water Pollution Prevention Plan (SWPPP): Developed and implemented stormwater management measures to protect surface water from pollutants during construction activities disturbing an acre or more in compliance with federal, state, and local requirements for permit approval under the NPDES program.

B. Orientation Meeting: The Park shall be responsible for arranging and conducting an Erosion and Sediment Control meeting/briefing to inform all parties scheduled to be on-site during the project of the measures to be implemented for proper erosion and sediment control (may be included as part of the Park’s internal Pre-Construction Meeting and again during the Contractor’s Pre-Construction Meeting).

1. Installation of silt fences, storm drain protection, and all other forms of erosion and sediment control shall not begin until after the internal NPS meeting has occurred.

C. Pollution Prevention and Erosion Control Manager: The Park shall designate the Pollution Prevention and Erosion Control Manager who will be responsible for the implementation, inspection, maintenance, and amendments to the approved plan.

1. The Pollution Prevention and Erosion Control Manager shall be familiar with temporary storm water pollution prevention procedures and Best Management Practices (BMPs) and shall ensure that emergency procedures and the plan are updated as needed and available for inspection.

2. When changes in the approved plan are required, the Pollution Prevention and Erosion Control Manager shall prepare and certify an amendment and submit the amended plan for internal NPS review and concurrence.
