Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health Why Isn’t Everyone Connected to a Municipal or Large Scale Sewage Treatment Plant o The simple answer is COST!!! -The collection and treatment of sewage is not cheap so the most cost effective thing to do is to spread those costs over a large population. -Large scale or municipal sewage systems are usually installed where the population density is greatest which leaves rural properties to fend for themselves. This is where On- lot Septic Systems come into play…

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health What is a On-lot Septic System? • First of all, the On-lot Sewage Regulation have only been around since the late 1960’s so there a lot of on -lot systems out there in Erie County that were installed that are no longer meet the current code:  Cesspools  Gravel filled pits  Discharges to old wells  Unpermitted direct discharges to streams/ditches including black and grey water Major components of a conventional On-lot Septic

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health How do I get one? The Application Process • Our staff process over 230 applications On-lot Septic Applications per year. Soil Evaluation • The Limiting Zone is: • Water • Depth to Water Table • Depth to Seasonal High Water Table (Mottling) • Slowly Permeable Zones • Depth to Bedrock • Depth to Clay or Fragipan • Zone of Poor Water/Soil Contact • Depth to zone of fractured rock, gravel, loose rock fragments

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health Perc Rate • Run Perc Test • Put water in hole and monitor its infiltration. • Have Soil Scientist evaluate the soil.

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health Conventional Beds & Trenches • Soil Conditions: • Limiting Zone  72 inches. • Perc. Rate: 6 to 90 min/in. 12 to 24 inch backfill 12 in aggregate 48 inches  72 inches

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health Elevated Sand Mound: • Soil Conditions: • Limiting Zone  60 inches;  20 inches. • Perc. Rate: 3 to 120 min/in. Top & Berm 12 in aggregate SAND  60 inches;  20 inches 5/8/2017

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health What is a Small Flow Treatment Facility? (SFTF) An individual or community sewerage system designed to adequately treat sewage flows not greater than 2,000 gpd for final disposal using a stream discharge or other disposal methods approved by the Department.

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health When does someone install a SFTF? ●After soil evaluations determine that the property can’t be approved for any other standard in-ground septic system ● If there is a stream or drainage swale on the property to discharge into (or on neighbor’s property with easement) ● After obtaining a two permits from the Department of Environmental Protection NPDES (National Pollutant Discharge Elimination System) for discharging and WQM (Water Quality Management) for construction and operations.

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health ECDH Oversight Program ● Provides a means by which municipalities can satisfy the DEP regulation governing SFTFs that requires the establishment of specific O & M requirements. Every township in Erie County signed on to our program, except Elk Creek Township ● Provides education to individual home and business owners on their responsibilities as an SFTF owner as well as specific O & M procedures required to properly maintain their system. ● Tracking of reporting requirements ● Conduct annual inspections by ECDH, if possible ● Follow up inspections to ensure system compliance ● Annual compliance reports sent to DEP and Municipalities

Lake Erie watershed discharges are displayed in yellow. Allegheny watershed discharges are displayed in red .

Erie County Department of Health www.ecdh.org www.ecdh.org Erie County Department of Health Program Challenges: • Systems have many violations and malfunctions so they need training and frequent monitoring; robust program needed • Together the systems pose a significant impact on local water quality • Office of the Great Lakes is seeking information on their impact on nutrient loading; mapping grant awarded. • ECDH does not have the staff to inspect these facilities; two SEOs already have a heavy workload • Previously staff were pulled from other programs and a per diem was hired. • Frequent property sales lead to need for education of real estate community, new property owners, and contractors.
