This amendment provides Q&A for a National Park Service requirement to clean and inspect water tanks at Crater Lake National Park. There is no discharge within 100 feet; the nearest discharge is Mazama dump station, about 7 miles from Garfield, 4 miles from Headquarters, and 1 mile from Mazama tank. Vehicle access is tight at Headquarters, and Garfield requires a 0.7-mile haul from parking to the tank; mechanical toters are allowed but limited to 36 inches wide, and ATVs are not permitted. Each tank has at least a 24-inch hatch, and Garfield is concrete half in-ground/half out while the other tanks are above-ground welded steel. Performance is flexible, with a total period of September 28, 2026 through July 31, 2027, and the park hopes the more complicated Garfield work can be completed before the end of October 2026, weather permitting, with possible seasonal shutdowns due to heavy snowfall.
