of 6`t'Avenue NW The site is owned by the Town of Catawba and contams the existmg wastewater treatment plant and a boat access ramp and parkmg The WWTP is situated on the upper portion of the property while the boat access ramp and parkmg area is located on the lower portion of the site The remamder of the property is undeveloped The site slopes toward Lyle Creek at the east edge of the property Attached pictures show the lower portion of the site where the buffer impacts will occur and the existmg effluent pipe 3e Describe the overall pro�ect A 3 0 million gallon per day(mgd) activated sludge treatment facility is planned for construction on the site ad�acent to the existing WWTP The facility will be implemented m phases Phase I will provide capacity for 1 5 mgd and Phase II is planned to complete the 3 0 mgd facility The exishng plant will be left in operahon unhl Phase I is completed The existmg WWTP will be taken off line when the new system is put mto operation The proposed pro�ect will consist of the construction of a new facility on the existmg property of the WWTP The design mcludes an automatic barscreen and gnt chamber m the headworks A splitter box will direct the waste stream into aeration basms for biological treatment The flow will come together once agam into a splitter box for routmg to the two parallel clanfiers for solids removal The sludge will be piped to the return activated sludge pump stahon where it can be wasted or returned to the head of the plant The effluent will proceed to the effluent structure where it can be filtered (if needed) pnor to introduction to the chlonne contact chamber for dismfection After disinfection the effluent will be dechlonnated and re aerated before dischargmg mto Lyle Creek as permitted by the North Carolma Department of Environment and Natural Resources (NCDENR) The effluent pipe for the treatment plant will be upgraded from the existmg 15 CMP to a 20 DIP discharge Sludge wasted from the plant will be pumped to a sludge holdmg tank and sent to the Hickory Regional Compostmg Facility F Supplementary Informahon Sd What data sources did you use to determine whether your site would impact
