Colorado Parks and Wildlife biologists did a field count of boreal toads, a state endangered species. Each toad caught was check for the chytrid fungus, which attacks amphibians by destroying their skin, disrupting their immune systems and causing heart failure as a way to assess the health of the boreal toad population. The biologists collect the toads eggs to be hatched to restock in locations in southwest Colorado to reestablish the population in the state., video file MPEG 159MB, Produced by Colorado Parks and Wildlife., Online resource; title from title screen (viewed May 2023)

The Colorado Oil & Gas Conservation Commission (COGCC) has been asked to use a risk-based strategy of inspection that will target the oil and gas operational phases that are most likely to experience spills and create a health risk to the public and environment. For each oil and gas spill reported to COGCC, Rule 906 requires that the responsible party fill out a Spill/Release Report, Form 19. For the last 20 years, the COGCC has required that spills associated with oil and gas activities that were five barrels (bbls) or greater in volume (or any volume if the spill impacted the State's waters) be reported using a Spill/Release Report, Form 19 (COGCC Rule 906.b). The contents of these forms have been input into the COGCC spills database., prepared for: State of Colorado Department of Natural Resources, Colorado Oil and Gas Conservation Commission ; prepared by S.S.
