South Padre Island Tar Patty March 2017 Response by: USCG TGLO Clean-up conducted by: Cameron County Parks, 3rd party contractor Potential Spill Amount: Unknown Actual Discharge Amount: 500 gallons Notification to Completion Time: 1 day Talking Points: Challenges (beach access for contractor, public safety, the tide can dictate the recovery time/efforts) These types of removal can be complicated due to the changing tides , distance into the water, and lack of a responsible party. Classified as tar patties, this occurrence is easier to clean-up but it is usually only speculation into who might be the responsible party. Discharge or natural seepage from the Gulf Of Mexico and beyond are a possible explanations for this type of pollution incident occurring.
