Documentation, sampling data, and any other records required\n\nby this section shall be maintained on site for as long as the\n\nfacility is in operation. Samples collected during the first year\n\nof the retention structure may be considered the baseline data and\n\nshall be retained on site as long as the facility is in operation.\n\nBaseline data for the facility shall be determined based on the best\n\ninformation available.","path":["OK Code","Title 2"],"source_url":"https://www.oklegislature.gov/OK_Statutes/CompleteTitles/os2.pdf","current_through":"2026-08-14","vintage":"open-us-law v2026.08, retrieved 2026-09-14","retrieved_at":"2026-09-14T18:32:36Z","sha256":"10c1fe88f8aee9ec97ba01424519143bdf6699ab8bcddf784b4cbe9168f0e16b","source_id":"us-ok","stale":false,"prev":"us-ok/okla.-stat.-tit.-2-2-20-49","next":"us-ok/okla.-stat.-tit.-2-2-20-51"},"notice":"GroundRules: Original legal text.
