18, 2025. The Temporary Operating Permit (TOP) for this project was issued on January 4, 2022. The TOP included conditions that required the Town to submit 3 years of spring flow data
before March 31, 2025. The required spring flow data was submitted with your POP request. Our understanding of the project is that the existing Lime Kiln Spring collection area wasreplaced
with new collection piping, drain gravel, 40 mil polyethylene liner and 3 feet of relatively impervious soil on top of the polyethylene liner. Two of the existing spring collectionboxes
were reused and one spring collection box was replaced. The Lime Kiln Spring is identifiedas WS001 in the Division’s database.
