The Department of the Interior, specifically the National Park Service, is seeking qualified businesses to address septic tank issues at the Santa Monica Mountains National Recreation Area through a Sources Sought Notice (SSN). The procurement aims to gather information on interested businesses and their qualifications for diagnosing septic tank problems, conducting septic tank pumping, and potentially repairing or replacing the septic system. This project is crucial for maintaining the environmental integrity of the park, which is primarily used by park staff and requires protective measures to minimize disturbance. Interested contractors must submit a completed Sources Sought Survey Questionnaire by 2:00 PM Pacific Time on January 20, 2026, to Contracting Officer Quinn Rankin at quinn_rankin@nps.gov, with a competitive Request for Quotations anticipated to be issued in early February 2026.
