Any building escorts are to be provided by the end user.

d. Access and Passes All Contractor employees, including subcontractors, subcontractors’ employees, suppliers, and suppliers’ employees are required to comply with the Installation Security Requirements regarding personnel, vehicle, and equipment security passes and access to the jobsite. Nothing in the contract is to be construed in any way to limit the authority of the Commanding Officer to prescribe new, or to enforce existing security regulations governing the admission or exclusion of persons or personnel and the conduct of persons while aboard the station, including but not limited to, the rights of search of all persons or vehicles aboard the station.

Coordinate with the Contracting Officer for specific security and access requirements.

a. Access to Buildings/Occupied Buildings: The Contractor may work in or around occupied buildings. The Contractor is responsible, via the Contracting Officer, to obtain access to the building and facilities and arrange for them to be opened and closed. Do not enter the building(s) without prior approval of the Contracting Officer. Contract personnel will not be permitted in security-regulated buildings or areas unless cleared by the Security Officer. In addition, buildings located within operational areas of the station, must be given approval by Range Control and therefore, must work with the Contracting Officers Representative (COR) to arrange for access to these facilities.

b. Passes and Badges: Contractor employees and representatives performing work under this contract are required to be either United States citizens or documented legal residents (status verified by the prime contractor). All Contractor employees must obtain the required contractor employee and vehicle passes. Each employee is required to wear and display the

Government issued badge over the front of outer clothing. Failure to obtain security and base access passes must not be a cause for contract performance time extension(s) or delays in performance of the contract. The Contractor is required to immediately turn in all terminated employee's badges to the issuing office.

c. Obtain access to Navy installations through participation in the Defense Biometrics Identification System (DBIDS). Requirements for Contractor employee registration, and transition for employees currently under Navy Commercial Access Control System (NCACS), are available at https://www.cnic.navy.mil/om/dbids.html. No fees are associated with obtaining a DBIDS credential. Participation in DBIDS is not mandatory, and Contractor personnel may apply for One-Day Passes at the Base Visitor Control Office to access the installation. Registration for DBIDS includes: Present a letter or official award document (i.e. DD Form 1155 or SF 1442) from the Contracting Officer that provides personnel the purpose for access to the base Visitor Control Center representative.

a. Present valid identification, such as a passport or Real ID Act- compliant state driver's license.

b. Provide completed SECNAV FORM 5512/1 to the base Visitor Control Center representative to obtain a background check. This form is available for download at https://www.cnic.navy.mil/om/dbids.html.

c. Upon successful completion of the background check, the Government will complete the DBIDS enrollment process, which includes Contractor employee photo, finger prints, base restriction and several other assessments.

d. Upon successful completion of the enrollment process, the Contractor employee will be issued a DBIDS credential, and will be allowed to proceed to the work site.

1.1 Dig Permit Approval

The Contractor is required to obtain a dig permit prior to the start of any construction or demolition related activities on-site. In order to obtain the dig permit, the Contractor must first obtain Miss Utility Ticket for the project site(s), so outside utilities such as, Verizon telephone and Comcast cable can be marked by the service provider. Once the utility ticket is obtained and the service provider has marked the utilities, then the utility ticket is forwarded to the Contracting Officer’s Representative (COR), so that the COR can have base utilities personnel mark all Government Owned utilities. At the conclusion of the utility markings, a dig permit will be issued to the Contractor via the COR. The permit is good for two (2) weeks at a time and will be re-issued by the Government; however, once marked, the Contractor is now responsible for up-keeping the utility makings throughout the contract duration.

1.2 Hot Work Permit

Prior to performing any “Hot Work” (e.g. welding, cutting or torching) or operating other flame-producing/spark-producing devices, request a written permit from the Fire Division.

CONTRACTORS ARE REQUIRED TO MEET ALL CRITERIA BEFORE A PERMIT IS

ISSUED. It is mandatory to have a designated FIRE WATCH for any “Hot Work” done on this activity. The Fire Watch shall be trained in accordance with NFPA 51B and remain on-site as required after completion of the task or as specified on the hot work permit.

7. OTHER PROJECT REQUIREMENTS:

Cultural Resources:

Buildings 312 and 360 are both historic and contributing elements of the Mainside Historic District. A Memorandum of Agreement has been developed to mitigate the adverse effects associated with their demolition that will require certain stipulations related to the demolitions.

This MOA will need to be executed prior to the demolition of these two specific buildings.

Coordinate with the Cultural Resources Program Manager prior to any work commencing on B.

312 or B. 360. Ground disturbance related to the demolitions should not impact cultural resources since the areas around the buildings are already heavily disturbed by construction and infrastructure. If suspected artifacts are discovered, stop work and contact the Cultural Resources Program Manager at 540-850-0698.

Natural Resources/Species Protection Conditions:

1. All buildings scheduled for demolition shall be inspected by the NRM prior to beginning activities for the presence of bat colonies or hibernating bats (depending on the time of year).

During the active colony season (01 March – 31 August), bat colonies shall not be removed/excluded without approval from Virginia Department of Wildlife Resources (VDWR) and work shall be conducted by a licensed nuisance wildlife control cooperator that is specifically authorized to conduct bat work. Demolition of buildings between 01 September and 28 February will require an inspection by the NRM to ensure hibernating bats are not present. A supplemental bat box of appropriate size shall be erected in close proximity to any building that is determined to be a bat roosting site and is scheduled for demolition prior to the beginning of demolition.

2. There is an osprey nest that is rebuilt and used each year at building 220 which is adjacent to building 217. If the nest is deemed active and contains eggs or young, then demolition of 217 would need to occur after the osprey nesting season to avoid impacting the nest efforts. If demo is slated to occur during the nesting season, then the nest can be removed as often as needed as long as there are no eggs and young present.

3. There has been historical evidence that ospreys nest on building 360 (Screen Tower) and similar time of year restrictions would need to be adhered to if a nest is established prior to demolition.

Earth Disturbance Conditions:

- Seed and straw disturbed areas. Seed mix shall not contain sericea lespedeza or Kentucky 31.

- If erosion control matting is needed, the use of 100% biodegradable material such as jute matting is required (non-biodegradable synthetic fiber erosion control matting is not permitted).

General Hazardous Component Abatement:

Reports, performed in 1990, identify that ACM are present in the B217 facility. A report for each of the following: asbestos, lead based paint, mercury, and PCBs will need to be performed to support this project at all demolition locations. The General Contractor is required to hire, as a first tier subcontractor, a PQP to ensure compliance with the approved work plans and perform independent inspections, testing and verification, and abatement of the hazardous components work including: asbestos, lead containing paint, mercury containing equipment, LLR components, PCBs, animal droppings, molds and spores. B116A is suspected to have ACM siding, but no report exists to substantiate.

Waste (Hazard and Non-Hazard) Conditions:

Worker Safety Lead and Asbestos Contamination:

- Lead and asbestos surveys must be performed on the work area prior to start of work. Asbestos surveys shall be performed by certified EPA AHERA Inspectors and lead surveys shall be performed by certified Lead Inspectors or Risk Assessors. Digital copies of laboratory analysis (asbestos/lead) from samples shall be forwarded to the NAVFAC South Potomac Lead Based Paint and Asbestos Program Manager (Paul Wenninger ), Dahlgren Environmental POC (Brendon Harp), and Safety Specialist (Jim Cole). If lead and/or asbestos-containing materials are identified the following conditions apply:

- Federal and State requirements for proper management of asbestos for demolition and disposal, included in (VSWMR) 9VAC20-81-620, and the National Emission Standard for Hazardous Air Pollutants (NESHAP) regulations, 40 CFR Part 61 Subpart M, contain standards for managing asbestos-containing waste materials (ACM). Requirements include: completion of proper surveys prior to work, development of proper work plans, notifications to regulators, implementation of proper controls and worker protection, proper supervisor and work licensing, waste disposal, and record keeping.

Waits, Kenneth.d.waits4.civ@mail.mil, 301-744-4855) for review and records maintenance. Waste (Hazard and Non-Hazard) Conditions

- Metal should be recovered from demolition for recycling to the maximum extent possible. Any recyclable metal with lead paint does not require removal of that lead paint prior to recycling. The lead paint may remain on the metal parts (stairs, window/door frames, metal siding, crane components, structural supports, etc.). Some of the remaining building materials contain lead. The entire waste stream for the demolition project will require TCLP testing for lead. If the entire waste stream TCLP's positive for lead, review the lead survey and remove all highly leachable lead components from the waste stream, then retest. Consult the NSF Dahlgren Environmental Office (Brendon Harp, 202-718-0655) for guidance.

- Contractor must coordinate storage of any generated hazardous waste with the NSF Dahlgren Environmental Office. Offsite shipments of any hazardous waste remain the responsibility of the contractor and may only be signed by a government employee specifically authorized by the Installation Commanding Officer, coordinated by the NSF Dahlgren Environmental Office.

Other Work Restrictions Contact the GIS Analyst upon project completion so that the Navy's GIS geodatabase can be updated (ie. buildings, structures, utilities, etc) Note:

GIS Analyst position is currently vacant, Interim POC: Rob Hupp, 201-757-4863 Buried Utilities Conditions

- Utility Location Required - No later than 5 business days prior to project execution, project manager must submit a request to Miss Utility for phone line location and submit a utility location request to the service desk (540-653-8230) for Mark Shelton (540-653-2766) to perform base utility location.

- PDS & TPDS Required - If site markings are purple, no excavation without prior notification from NSWCDD 1041 (540-653-3142/6309).

General Explosive Contamination Abatement:

Structures, in which explosive materials have been managed and/or stored, may contain explosive residues hidden within cracks, crevices, under flooring, in ventilation ducts, behind wall panels, etc. Friction or impact from dismantling the structural components can present a potential detonation hazard that must be evaluated and addressed prior to dismantling/demolition operations.

The decommissioning and demolition of an explosives- contaminated structure may present unobvious hazards requiring application of specialized knowledge and expertise as well as implementation of established regulatory safety programs. Consequently, the decommissioning and demolition of structures should be preceded by a comprehensive planning process and be conducted in accordance with both established and project-specific safety procedures. This process shall include a Safety and Environmental Hazard Review and Site Inspection, Work Plan Development, Obtain Permits, Gain Approval, Implementation of Work Plan, Test Debris and Soil for Reactivity/Toxicity. Activities involving ammunition and explosives or their constituents or chemical warfare agents have additional requirements as specified in EM 385-1-97, Explosives Safety and Health Requirements Manual. If tests show no reactivity/toxicity in

Structures Containing Blasting Agents:

Decontamination of structures that have contained blasting agents composed of high percentages of water soluble, hygroscopic salts such as ammonium nitrate and fuels may be achieved by sweeping or other physical means. Water wash down usually results in the safe decontamination of this building category. In certain cases, collecting and treating the wash down water may be required.

Open burning is not recommended for this explosives contaminated building category. Structures Containing Black Powder and Pyrotechnic Mixtures: Decontamination of black powder and similar pyrotechnic mixtures may also be achieved by mechanical cleaning followed by water wash down.

However, due to the ease of ignition after drying, burning is recommended for this building category.

Structures Containing Other Explosive Chemicals and Compounds:

Water insoluble molecular explosives such as nitroglycerin, tetryl, TNT, PETN, RDX, and HMX require special decontamination and dismantling procedures. These procedures may include sweeping and physical removal followed by steam cleaning of equipment and the use of solvents, such as acetone, or a desensitizing oil prior to the removal of threaded fittings. Trinitroresorcinol, lead styphnate, lead azide, mercury fulminate and other initiating explosives are quite sensitive to initiation by heat, impact and friction. These materials present the supplemental problem of residual metal contamination after the criteria of reactivity is eliminated. Structures that have contained these two groups of explosives require soil monitoring to assure complete, safe closure of the site.

Bioremediation or ash and soil removal may be required. It is highly recommended that buildings used to manufacture or process any of these two groups of explosives be burned to eliminate possible hazards associated with reactive materials that may have accumulated in cracks, crevices or larger spaces within the floors and walls.

Unexploded Ordinance (UXO)/Munitions & Explosives of Concern (MEC) Monitoring & Clearance:

- Bldg. 102 shall be downloaded of all explosives while facilities 312 and 360 are being demoed.

- All ammunition and explosives shall remain at rest inside of Magazine Area 2 while facility 1312 is being demoed.

- A UXO surface sweep shall be conducted by EOD or a Certified UXO Technician prior to the demolition of facility 360 (Main Range Tower) to ensure the area of work is clear of UXO/MEC.

- To avoid concurrent explosive operations, all work shall be coordinated and scheduled with Range Control (x540-653-8791) at least 5 days in advance. POC for scheduling is Michael White.

- There shall not be any ammunition/exploisve testing conducted on Main Range while facilities 312 and 360 are being demoed.

- Onsite Construction Workers shall contact Range Control (x540-653-8791) daily prior to the start of work to ensure explosive operations are not being conducted in the areas of facilities 312, 360, and 1312.

- Onsite Construction Workers shall adhere to range barricades and postings at all times, and shall only gain permission from Range Control prior to entering an area that has been barricaded.

- The likelihood of encountering UXO/MEC in the area of facilities 1312, 217, 2014, and 116A is very low. In the unlikely event a suspect explosive item is found, contact Range Control @540-653- 8791 or Dispatch @ 540-653-8291/8095 for EOD support.

- If MEC is found for any of the facilities being demoed, then work will not recommence until follow-up actions by the NSWCDD/NSASP ESO have taken place.

- See attached ESR MEMO for any additional Explosive Safety comments/requirements.
