STATEMENT OF OBJECTIVES (SOO)

Site Maverick drainage

HUAC JAJ30515-8J-Building 12584

Walkway to Entrance of Building Needs Permanent Fix

05 AUGUST 2022

1. Project Background

This project aims to reduce flooding near Building 12584. This location is in a remote mountainous area.

2. Statement of Objectives

2.01 This is a design/build. The Contractor shall provide design and build services and furnish all labor, material, equipment, supervision, transportation, permits, fees, licenses necessary to add an approved storm drain system for Building 12584, located at Fort Huachuca, AZ. A non-specific Statement Of Work (SOW) for this repair project is provided in Section 4, below. The Contractor shall prepare a more detailed SOW outlining their Contract Execution Overview, to include their technical approach, and tentative schedule. The Contractor shall field verify the area of work before submitting their SOW and proposal.

2.02 Environmental Work Statement clause for all exterior work:

Through the Arizona Pollutant Discharge Elimination System (AZPDES) permitting program, the Arizona Department of Environmental Quality (ADEQ) regulates the discharge of storm water from construction sites throughout the state including those on military installations.

“Construction” refers to actions that result in a disturbance of the land, including clearing, grading, excavating, and other similar activities. It also includes “construction-related activities” areas that support the construction project such as stockpiles, borrow areas, concrete truck washouts, fueling areas, material storage areas and equipment storage areas.

The AZPDES Storm water Program requires operators of construction sites which are one acre or larger, including smaller sites that are part of a larger common plan of development, to obtain authorization to discharge storm water under an AZPDES construction storm water permit. The Contractor is responsible for determining whether a construction site will exceed this minimum threshold and for obtaining coverage under an AZPDES construction storm water permit.

Obtaining coverage under an AZPDES permit entails preparing and implementing a Storm Water Pollution Prevention Plan (SWPPP) in accordance with ADEQ requirements and submitting a Notice of Intent (NOI) for coverage under the applicable AZPDES general permit.

Once ADEQ receives the NOI, ADEQ then issues an authorization certificate to the Contractor.

If a contractor has a subcontractor working together on the same project, then the contractor and subcontractor(s) will have to submit an NOI for the same job and separate authorization certificates will be issued to each party.

If the Contractor determines that the project will not exceed the minimum threshold and does not submit an NOI and it is later determined that the threshold is exceeded, the Contractor will be required to stop all work until they have completed the above process. If the appropriate documentation is not provided to the Government prior to the start of construction or once the threshold is exceeded, the Contracting Officer will be notified of the failure to comply with a contract requirement, the ADEQ Enforcement Section will be notified, and other appropriate action will be taken to resolve the matter. The Contractor and any subcontractor(s) will be liable for any fines levied by ADEQ.

A critical component of the SWPPP is final site stabilization. This generally involves restoring the disturbed area to at least 70% of its former vegetative state. After implementing all aspects of the SWPPP, to include final site stabilization, the Contractor submits a Notice of Termination to ADEQ, ending coverage under the AZPDES permit.

An example SWPPP can be found at the following website:

http://cfpub1.epa.gov/npdes/stormwater/swppp.cfm

The Contractor is encouraged to follow the format and content of the sample SWPPP. It is the responsibility of the Contractor to develop a SWPPP that meets applicable requirements. The Government will not review the Contractor SWPPP for compliance with applicable laws. The Contractor and any subcontractor(s) shall provide a copy of the ADEQ Authorization Certificate and a copy of the SWPPP to the Government employee performing construction oversight prior to any construction or construction-related activities as defined above.
