NASAP Program Enrollment and Drug Testing for Contractors

Do you need site access with NASAP (North American Substance Abuse Program)?

DISA helps contractor companies enroll employees, complete required drug and alcohol testing, manage employee status, and maintain NASAP compliance.

When DISA manages your NASAP enrollment, your workforce can also gain reciprocal access to hundreds of participating DISA sites in the DISA Contractor Consortium. Instead of needing multiple providers, DISA grants eligible workers access to all urine-testing NASAP and DISA-mandated sites. Contractors may choose another provider, but will not receive reciprocity to DISA Contractor Consortium sites.

What is NASAP?

NASAP stands for the North American Substance Abuse Program.

NASAP is a standardized contractor employee drug and alcohol testing program designed for contractor employees who need access to participating owner sites. The program centralizes reporting, supports rehabilitation requirements, and helps participating owners and contractors reduce unnecessary testing and administrative expense.

DISA is listed by the Industry Business Roundtable as a qualified NASAP Consortium Third-Party Administrator.

Why Choose DISA as Your NASAP Administrator?

A NASAP provider helps your company manage enrollment, required test notifications, laboratory and medical review processes, database status, and ongoing compliance support.

In addition, DISA provides an additional benefit. Your NASAP program with DISA as your provider also grants you reciprocal access to participating DISA Contractor Consortium sites that mandate urine testing. This means your workers gain access to several hundred additional sites with no additional program requirements.

This broader network helps contractors:

» Manage one provider across more participating owner sites
» Reduce duplicate drug testing
» Reduce separate random testing pools
» Limit scheduling, travel, and collection time
» Keep more productive labor hours on the job
» Consolidate drug testing, background screening, and occupational health services

NASAP Drug Testing Requirements

» Pre-Enrollment & Pre-Access: New hires must pass an initial urine drug and alcohol test to become "Active".

» Random Testing: The program maintains a strict random testing pool requiring a 50% annual draw for drugs and alcohol.

» Reasonable Suspicion & Post-Accident: Testing is required if a supervisor documents reasonable cause. Post-accident testing is mandated following qualifying incidents.

» Substances Tested: NASAP uses a standard 10-panel drug test, including Marijuana (THC), Cocaine, Amphetamines (including MDMA/Ecstasy), Opiates (including Oxycodone), Phencyclidine (PCP), Barbiturates, Benzodiazepines, Propoxyphene, Methadone, and Methaqualone.

Check the Math!

You have a 20-person contractor crew working at 4 nearby owner sites, each with a 50% random-rate. If some sites mandate DISA and other sites mandate NASAP, it makes sense to choose DISA.

With DISA as your NASAP provider, you:

» Have access to all 4 sites with 1 program
» Manage 1 program for all employees
» Conduct 10 random selections annually

If you enroll in NASAP with a different provider, you would need to:

» Manage 2 separate programs
» Random selections double to 20 annually
» Screening program costs double

Your workforce should spend more time on the job and less time repeating screening requirements.

Choosing a NASAP provider is more than checking a compliance box. The provider you select affects how many participating owner sites your workforce reaches without enrolling in additional programs.

DISA is the only NASAP provider that also provides reciprocal access to hundreds of participating DISA urine consortium sites. As crews move between projects, one provider supports more owner requirements, reducing duplicate enrollments, repeated random testing, and unnecessary administrative work.

That broader reciprocity translates into measurable savings. In 2025, participating DISA contractors avoided 178,600 redundant tests and saved $21.9 million in direct testing costs. Those figures do not include reduced travel, recovered labor hours, or the value of getting qualified workers onto participating sites sooner.

Start NASAP enrollment with DISA to simplify contractor compliance, reduce duplicate testing where reciprocity applies, and help your workforce meet more owner-site requirements through one provider.

What does NASAP stand for?


NASAP stands for the North American Substance Abuse Program. It is an industry drug and alcohol testing program for contractor employees working at participating owner sites across North America.

The program establishes consistent testing, reporting, rehabilitation, and compliance requirements. This structure helps owners maintain safer workplaces while giving contractors a standardized process for managing employee eligibility across participating sites.

What is the purpose of the NASAP?


To provide a safe and substance-free contractor workforce while protecting employee rights and privacy. NASAP includes a rehabilitation process and keeps individuals who test positive from moving between contractor companies without completing an approved rehabilitation program.

NASAP helps to reduce unnecessary testing redundancy that now exists for many contractors, thereby reducing the overall administrative costs for both owners and contractors. Additionally, contractors have a choice of who administers NASAP. Third-Party Administrators (TPAs) will have to earn the business and perform to keep it.

Contractors choose DISA because of our larger network of owner sites. By using DISA to manage a NASAP program, contractors gain access to hundreds of additional sites without needing an additional program. As the number of participating sites a contractor visits increases, pre-employment and pre-access testing is greatly reduced.

Is DISA a NASAP provider?


Yes. DISA is a qualified NASAP Consortium Third-Party Administrator, also known as a C/TPA. DISA manages contractor enrollment, testing coordination, compliance records, employee status, and other administrative requirements associated with the NASAP program.

Choosing DISA also gives contractors access to DISA’s broader urine-testing consortium network. When applicable requirements are met, employees enrolled through DISA receive reciprocal access to both NASAP sites and participating DISA owner sites through one provider.

Is NASAP the same as the DISA Contractor Consortium?


No. NASAP is an industry program supported by participating owners and administered through qualified C/TPAs. The DISA Contractor Consortium is DISA’s broader contractor compliance network, which serves additional owners across multiple industries and locations.

When DISA manages your NASAP enrollment, your company receives the required NASAP administration plus access to participating DISA urine-testing owner sites. This broader reciprocity helps reduce separate programs, duplicate testing, added paperwork, and time away from the job.

Does NASAP provide access to every owner site?


No. NASAP supports access ONLY to owner sites participating in the NASAP program. Other owners use separate drug and alcohol testing requirements, including the DISA Contractor Consortium or other owner-specific programs.

Choosing DISA as your NASAP administrator expands your potential site access. Your workforce receives support for NASAP requirements and participating DISA urine-testing consortium requirements through one provider, subject to each owner’s policies and eligibility standards.

Does choosing DISA change NASAP requirements?


No. DISA administers the established NASAP program requirements. Choosing DISA does not remove, replace, or reduce any owner-site requirements.

The difference is the additional value your company receives. DISA combines NASAP administration with access to its larger contractor consortium network, helping your workforce meet additional owner requirements without managing separate providers.

What are a contractor's responsibilities under NASAP?


1. Establishing a business relationship with a NASAP TPA like DISA.

2. Having employees sign a one-time Global Release form and sending these to the selected TPA.

3. Ensuring that employees are active in the NASAP database by doing a drug screen look-upbefore sending workers for substance abuse testing and/or the worksite. (Note: manufacturers may use gate-check procedures to ensure NASAP eligibility. Non-eligible employees will be denied access.)

Ongoing compliance includes conducting random and other required tests per the TPA, ensuring that Contractor employee rosters are updated to the TPA at least monthly upon TPA request, ensuring that employees new to the NASAP have signed global consent forms sent to the TPA, etc.

More NASAP FAQs

I need NASAP for owner-site access. Do I have to use a specific provider?


No. Participating owners require NASAP, but contractors typically choose which qualified NASAP C/TPA administers their program. Choosing DISA provides the added benefit of broader reciprocity across participating DISA owner sites, reducing the need for multiple programs when crews work across different facilities.

What is the role of the Health and Safety Council (HASC) in NASAP?


The Health And Safety Council maintains the NASAP database.

What is the role of the TPAs when drug testing with NASAP?


TPAs will administer the NASAP for participating employees of their contractor clients. Administration includes notification of required tests, specimen collection and testing, database management, medical reviews, referrals to substance abuse professionals for rehabilitation, and maintenance of status information for employees.

Additionally, TPAs train appropriate contractor employees who will be involved in administering the substance abuse program.

TPAs will report employee statuses to the Houston Area Safety Council and will coordinate with other TPAs as employees transfer to other employers.

Does NASAP apply to workers subject to DOT drug testing?


The employer needs to check with the facility representative to determine if the facility requires a NASAP test for employees covered by the DOT program. Some facilities require both tests, while others accept the DOT test depending on the duties the worker will be performing at the site.

How is NASAP affected when a worker changes contractor companies?


For example, Person A was hired by Contractor X and is tested by one of the TPAs. Later, the same worker is hired by Contractor Y, which uses a different TPA. Does the person need to be tested again? How is the TPA aware that the worker is already in the NASAP pool? The worker will stay “Active” on the NASAP database if he/she does not miss a random test or tests non-negative regardless of who the worker’s employer is. Contractor Y must do a NASAP look-up to see if Person A is in the database and discern their status. Person A does not have to be re-tested unless the database shows the individual is “Inactive”. It is the responsibility of the employer to call the TPA to determine why the person is “Inactive”.

Are Social Security Numbers required for the NASAP database?


Social Security Numbers are required since employees are tracked from employer to employer. The NASAP database follows all state and federal laws and acceptable security standards.

What is the role of the Three Rivers Manufacturers’ Association (TRMA) in NASAP?


TRMA provides a drug-screen look-up function for contractors and manufacturers through the Virtual Safety Council. The Virtual Safety Council is the same software through which contractors order background checks, register for training, check training history, etc.

Does the test history show when a NASAP lookup is performed?


There are 2 different ways to do a NASAP look-up: through the TRMA online system or through the Contractor’s TPA website. Only “active” or “inactive” status will be displayed on the TRMA online system. When doing a NASAP look-up through the Contractor’s TPA website more information may be displayed including the test results, dates, “Authoritative TPA”, etc.
