8. Security Requirements.

8.1. Levels of Security. Dyess AFB security may be viewed as being one of three broad levels, the level in effect being dependent on the location or AREA of Dyess AFB in question.

8.1.1. The lowest level of security exists in “GENERAL ACCESS” areas. These areas are all of Dyess AFB outside of the "USAF Controlled" and "USAF Restricted" areas.

8.1.2. “USAF Controlled” access areas are the mid-level security areas. Presence within the CONTROLLED ACCESS AREA is by authorization; however, the movement of authorized personnel in and out of these AREAS is generally not impeded.

8.1.3. The highest level of security on Dyess AFB is that within the “USAF RESTRICTED AREAS”. These areas are subdivided to be known as Protection Level 1, 2 or 3 AREAS.

Work schedule requests or changes to existing schedules for work to be performed in a “USAF RESTRICTED AREA” shall be submitted at least 7 calendar days in advance for approval and coordination of Dyess AFB Security Forces.

8.2. Closed Base. Dyess AFB is considered a closed base. All personnel entering must have specific permission of the installation commander for entry. This permission is granted when a Contractor employee is issued an identification card. The Contracting Officer will provide information necessary to obtain identification cards. The contractor shall be responsible to ensure that all of its employees obtain, and keep on their person at all times while working on the base, a USAF identification card. Upon completion of the work or termination of an employee, the contractor shall be responsible for turn in of identification cards to the Contracting Officer or to the Pass and Registration Office of the Security Forces.

NOTE: Failure to turn in badges will result in WITHHOLDING OF FINAL PAYMENT and revocation of any future badges issued by the Pass and Registration Office to the employee and the contractor.

8.2.1. Dyess Form 173. The Dyess AFB Form 173 is subject to the privacy act of 1974, Authority:

10 U.S.C. 8012 and 5 U.S.C. 552a (b) (7). Disclosure is Mandatory: Failure to provide the information and Social Security Number (SSN) could result in denied access to the Dyess AFB installation.

8.2.1.1. Effective 1 Nov 04, a completed signed original Dyess Form 173 (Mar 04) must be delivered to Pass & ID by 0900 on the duty day prior to the desired day of entry onto Dyess AFB. The Visitor Control Center no longer issues temporary passes to contractor personnel unless they have already been previously identified on an executed Dyess Form 173. All information on the Dyess Form 173 must be typed and the authorizing signature must be in blue or black ink. Personal information provided on the Dyess Form 173 will be cross-referenced against state and federal criminal databases to identify those individuals possessing outstanding warrants. Those individuals with outstanding warrants will be detained at the Visitor Control Center on the desired day of entry, and turned over to Abilene Police Department.

8.2.1.2. The approving authority (individual on the 577) can make “ink changes” in red ink to correct any errors noted on the form. All changes have to be initialed by the approval authority.

8.2.1.3. All individuals with Dyess Form 173’s will still continue to be processed via the Texas Law Enforcement Terminal System (TLETS—police wants/warrants check). Once it is determined the individual is cleared from any wants or warrants, a copy of the Dyess Form 173 will be placed at the Tye Gate entry point. The Tye Gate Guard will use this form as an Entry Authority List (EAL) allowing contractors onto the installation. The contractor will then be able to go to the Gate directly (not the Visitor Control Center (VCC) or Arnold Gate) and verify if their Dyess Form 173 is there. Should their Dyess Form 173 not be there, they will be directed to the VCC for issuance of an AF Form 75.

At this time, someone will physically have to meet them to sponsor them onto the installation. (Reasons why the form would not be at the guard shack would be erroneous driver’s license number, erroneous information, warrant, or identified as illegal alien).

8.2.1.4. Should their Dyess Form 173 be at the Tye Gate entry point, the contractor will be told to proceed directly to the Pass and Registration Section for the 7 SFS Contractor Badge issue. The Pass Section will have the original Dyess Form 173. Once a badge is obtained, they need only show the badge at the installation gate for entry onto the installation. Please note that neither the Security Forces Control Center nor the Tye

Gate Guards will check the Dyess Form 173 for errors. This is the responsibility of the Pass and Registration Section.

8.2.1.5. The Dyess Form 173 will be maintained at the Tye Gate entry point for 48 hours (two business days). After the specified time has expired, it will be destroyed. Should the contractor not process through Tye Gate in that 48-hour period, the contractor will require someone to physically vouch them on base to get a one day pass at the VCC so they may proceed to the Pass and Registration office for their badge. The hold period for these forms at the gate can and will be extended should rain days occur or through prior coordination with any affected agency.

8.2.2. Trusted Agent Letter for Day Labor Requests.

8.2.2.1. Purpose of Letter: To provide sponsoring authority to specific contractor individuals as identified by their sponsoring agency (7 CONS, Army Corp of Engineers, etc.) to sponsor day laborers on for one day periods.

8.2.2.2. The Letter Process:

8.2.2.2.1. The sponsoring agency, in coordination with their contractor, will identify contractor individuals that require sponsoring/vouching authority. This authority is given to the contractor for the purpose of sponsoring day laborers/job site personnel sub-contracted as a result of an unexpected or new requirement not previously identified in the current contract. This authority will not be given to contractors for convenience only but should be limited to the smallest group of manager or foreman contractor personnel needed to complete their assigned contract. It is the responsibility of the sponsoring agency to ensure the Trusted Agent Letter remains current. Additionally, all reasonable actions should occur to prevent use of this process when a known laborer/sub-contractor was required well in advance of the day labor/sub-contractor request. (Effective Date: Immediately)

8.2.2.2.2. The sponsoring agency will provide this letter to the Pass and Registration Section who will maintain it on file. The Pass and Registration section shall post a copy of the letter at the VCC, as a reference, to verify which contractor personnel have sponsoring/vouching authority.

8.2.2.3. The Process to get Day Labors/Job Site Personnel Sub-Contracted onto the

Installation:

8.2.2.3.1. The contractor individuals identified in the Trusted Agent Letter will provide a typed or hand-written form (form will be provided by the 7 SFS) with all individuals they will sponsor onto the installation to the VCC Guard. The VCC Guard will verify the identity of all individuals on the form by checking the information against a valid State/Federal Identification card. The VCC Guard will randomly check a percentage of the individuals via the TLETS. Should any individual not possess a valid identification card, they will be turned away at the VCC and entry to the installation denied. Pen and ink changes can be made to the form, but all information must be validated by the guard before the contractor will be allowed to proceed onto the installation with the sponsored individuals. No AF Form 75/Visitor Pass will be issued to any individual who is sponsored by the Trusted Agent Contractor, unless the sponsored individual will be driving a vehicle onto the installation. Trusted Agent Contractors are encouraged to consolidate all sponsored individuals into the smallest number of vehicles as possible to avoid the issuance of multiple AF Forms 75. Should an AF Form 75 be issued, the driver will be required to produce a valid driver’s license, current insurance card, and current registration for the vehicle being operated. Once on the installation, the Trusted Agent Contractor will be responsible for the actions of the sponsored individuals. Should an incident occur with a sponsored guest, and negligence be proven on the part of the Trusted Agent Contractor, their vouching/sponsoring authority will be revoked. The Trusted Agent Letter can be adjusted to add and delete names of Trusted Agent Contractors as needed, as long as the provisions of this paragraph are followed. Although the 7 SFS form is used in lieu of the AF Form 75, it carries the same authority and responsibilities.

Additionally, the 7 SFS Form will expire at 0001 daily or at the end of the contractor duty day, whichever occurs first. At no time will the Trusted Agent Contractor depart the installation and leave any of his/her sponsored individuals with another contractor that does not have the same vouching/sponsoring privileges.

8.2.2.3.2. All contractors must attend a contractor briefing given to the contractors by Pass and Registration who will provide a more detailed explanation regarding contractor badges and their uses. Pass and Registration reserves the right to not issue a contractor badge due to erroneous information or failure to disclose information on the Dyess Form 173. Any derogatory information received from the background check will result in the non-issuance of the contractor badge.

9. Identification of Contractor Vehicles. Contractor vehicles must be marked on each side with company name with either permanent or semi-permanent/magnetic signage.

10. Other Vehicle and Licensing Requirements:

10.1. All contractor employees who will be driving a vehicle on Dyess AFB shall have a current driver’s license with them at all times while on Dyess AFB.

10.2. All contractor vehicles to be operated on Dyess AFB will have a valid state registration, vehicle inspection, and insurance. Proof of registration and vehicle insurance must be physically available at all times while the vehicle is on Dyess AFB.

10.3. Any contractor employee who will be operating heavy equipment or specialized equipment that requires a license or certification shall be so licensed and/or certified with proof presented to the contracting officer prior to work start.
