Summary Household sewage treatment systems (HSTS) and small semi-public systems (referred to as package plants) are used in areas where municipal sanitary sewers are not available or accessible. These small treatment systems represent a potential source of nutrients (e.g., nitrogen and phosphorus) to Lake Erie, and promote growth of harmful algal blooms. The goal of this project was to identify areas in the Ohio portion of the western Lake Erie basin (WLEB) where sanitary sewage infrastructure improvements should be made to support the phosphorus load reduction of 40% set by the Great Lakes Water Quality Agreement. The objectives were to (1) map known sanitary sewer service areas, (2) estimate nitrogen and phosphorus loads from HSTS within the unsewered areas, (3) update the inventory of package plants and estimate their phosphorus loads, and (4) identify critical sewage areas (CSAs) where there are dense housing units in unsewered areas.

Sanitary sewer areas were delineated using Geographical Information System (GIS) based on information provided by municipalities and county engineers. Total phosphorus and nitrogen loads from HSTS were estimated using data from literature, U.S. census data, and GIS analysis. Phosphorus loads from package plants were quantified using information obtained from National Pollutant Discharge Elimination System (NPDES) permits and existing data for package plants without a permit. Critical sewage areas were delineated based on information provided by county health departments and sanitary engineers, and review of county parcel maps.

HSTS accounted for 80.49 metric tons annum (mta) of total phosphorus and 784.45 mta of total nitrogen. Nutrient loads from HSTS were derived from population, so it was typical the loads increased in areas with higher population. The highest loads were observed in Lucas, Wood, and Allen counties: total phosphorus – 9.78, 9.55, and 7.25 mta; total nitrogen – 95.34, 93.06, and 70.68 mta, respectively. Ten sub-watersheds (12-digit hydrological unit code) were highlighted because the total phosphorus loads from HSTS exceeded 1.0 mta, these included Cedar Creek, Wolf Creek, Crane Creek, Heldman Ditch, Preston Run, Ai Creek, Portage River, Sugar Creek, Dog Creek, and Rocky Ford.

Package plants accounted for 8.97 mta of total phosphorus. A total of 196 package plants were identified, with 145 (74%) having NPDES permits. Most (n=104) of the plants had a capacity less than 10,000 gallons per day (gpd); these smaller plants have no total phosphorus limit for effluent. Ottawa County had the most package plants (n=48) and greatest cumulative phosphorus load (2.66 mta).

CSAs were identified in 17 of the 19 counties, with 31 located in Lucas County. Areas that included more than 50 housing units are of concern due to the potential to contribute elevated loadings of nutrients and bacteria. A total of 60 CSAs with at least 50 housing units were identified, with 12 located in Lucas County and 11 in Ottawa County.

Based on the results from this project, TMACOG supports the following actions: • Identify and map all existing home sewage treatment systems, with efforts focused on the 10 HUC-12 watersheds with elevated total phosphorus loads. • Connect housing units and package plants to available and accessible sanitary sewers. • Establish total phosphorus limits for all package plants, especially plants with a capacity less than 10,000 gpd. • Prioritize CSAs, with focus on those with documented unsanitary conditions, such as elevated levels of nutrients and bacteria.

1. Introduction Water quality in western Lake Erie has increasingly become degraded, as demonstrated by excessive nutrients (Jarvie et al. 2017), recurring harmful and nuisance algal blooms (Ho and Michalak 2017), and public beach closings (ODH 2017). Elevated levels of phosphorus facilitate the growth of algal blooms (Michalak et al. 2013), and recently nitrogen was identified as another growth limiting nutrient (Gobler, et al. 2016; Levy 2017). Algal blooms in western Lake Erie are dominated by Microcystis that produces microcystins, which are toxins that affect the liver. In August 2014, elevated levels of microcystins at the Toledo water treatment plant resulted in a temporary ban of the drinking water to approximately 500,000 regional residents. To address these growing challenges of Lake Erie, governments of Canada and the United States adopted targets under the Great Lakes Water Quality Agreement (GLWQA) Nutrients Annex Subcommittee to reduce phosphorus entering western Lake Erie by 40 percent (USEPA 2015).

Impairments to Lake Erie are a direct result of terrestrial activities that occur within the watersheds that empty into the lake. The western Lake Erie basin (WLEB) (Figure 1) is approximately 9,300 square miles and is dominated by agricultural activities that account for almost 70% of the total land area (USDA, NRCS 2016a). Studies indicate that agricultural practices are the primary sources of nutrients. For example, Scavia et al. (2016) estimated that 85% of the total phosphorus load from the Maumee River is derived from farm fertilizers and manures, and the Ohio Environmental Protection Agency (Ohio EPA) estimated that non-point sources (comprised mainly of agriculture sources) account for 88% of the total phosphorus load (Ohio EPA 2016). The remaining phosphorus load is generated by point sources, which are discharging facilities permitted by Ohio EPA through the National Pollutant Discharge Elimination System (NPDES) program, and household sewage treatment systems (HSTS).

As expected, efforts to reduce nutrient loads have been directed towards agriculture, with costs for implementing conservation practices in the WLEB reported to be $277 million in 2012 (USDA, NRCS 2016b). Positive results from conservation practices include reductions in sediment, total phosphorus and nitrogen lost from farm fields, but soluble phosphorus losses remained the same (USDA, NRCS 2016b). Despite these costly efforts, it is evident from the record setting algal bloom in 2015 that additional strategies are needed to reduce the nutrient loads entering Lake Erie. Accordingly, it is necessary to assess the nutrient contribution from other potential sources and identify solutions to reduce their nutrient inputs.

HSTS are a potential source of nitrogen and phosphorus to surface and ground waters. These systems are used to treat and dispose domestic wastewater in areas where sanitary sewers are not available or accessible. Typically, the wastewater undergoes primary treatment in a septic tank via sedimentation with secondary treatment completed in a leach field by means of soil adsorption. Design specifications and effluent standards differ by state, and effluent data for HSTS are highly variable. For example, reported values for total nitrogen range 40-237 mg/L and total phosphorus range 10-26 mg/L due to the age and type of system, and site-specific soil conditions (Whelan and Titamnis 1982; Beavers and Gardner 1993; Gardner et al. 1997; Charles

4 | P a g e

et al. 2004). The Ohio Department of Health (ODH) completed a statewide survey in 2012 (ODH 2013) to assess the failure rates of HSTS. Results of the survey indicated an overall failure rate of 31% for the state with the highest rate of failure (39%) in the northwest region. The high failure rate in northwest Ohio is not surprising because of the regional soil conditions that have inadequate drainage and high seasonal or perched water tables.

In addition to HSTS, larger on-site sewage treatment plants known as “semi-public” systems and herein referred to as “package plants” are potential sources of nutrients to surface and groundwater in areas with no public sanitary sewer available. Package plants are small wastewater treatment systems, commonly prefabricated, that function to treat wastewater from businesses or residential developments that is generated at a rate that exceeds the capacity of a septic system. In general, package plants are rated from 1,500 gallons per day (gpd) to 100,000 gpd and consist of one large tank that is subdivided into an aeration chamber, a clarifier, and a disinfection unit (Water Pollution Control Federation 1985). On-site effluent that has not been properly treated may cause water quality impairments through elevated loadings of nutrients and bacteria.

At the present, there have been no studies to assess the contribution of nitrogen and phosphorus loads by HSTS for the entire WLEB. This is due to the limited data available for HSTS such as the number and type of individual treatment systems, and nutrient removal efficiencies for the treatment systems. However, Ohio EPA estimated nitrogen and phosphorus loads from HSTS for major watersheds in Ohio for water years 2013-2017, including portions of the WLEB. Their study determined that HSTS accounted for 1-11% of the total nitrogen load and 3-17% of the annual total phosphorus load for the watersheds they examined (Ohio EPA 2018). Ohio EPA also estimated the nitrogen and phosphorus loads from all wastewater treatment facilities with NPDES permits (including municipal wastewater treatment plants [WWTP] and package plants), which accounted for 3-93% of the total nitrogen load and 2-69% of the total phosphorus load for the watersheds in their study (Ohio EPA 2018).

This project complements the work completed by Ohio EPA by estimating total nitrogen and phosphorus loads from HSTS and total phosphorus loads from package plants throughout the Ohio portion of the WLEB. However, this project differs from the Ohio EPA study because sanitary sewer service areas were delineated using information obtained from municipalities and county engineers. Additionally, the estimated total phosphorus loads from package plants was derived using data from both NPDES permitted and non-permitted plants.

Goal Identify wastewater infrastructure improvements within the Ohio portion of the western Lake Erie basin that support the target phosphorus load reduction of 40% set by the Great Lakes Water Quality Agreement.

2. Methods Study Area The WLEB covers approximately 9,300 square miles of northwest Ohio, northeastern Indiana, and southeastern Michigan (Figure 1). The WLEB is comprised of 10 hydrologic unit code (HUC) 8- digit watersheds: Auglaize (04100007), Blanchard (04100008), Cedar-Portage (04100010), Lower Maumee (04100009), Ottawa-Stony (04100001), River Raisin (04100002), St. Joseph (04100003), St. Marys (04100004), Tiffin (04100006), and Upper Maumee (04100005); there are a total of 333 HUC 12-digit watersheds (Appendix A). The study area in this project consisted of only the Ohio portion (approximately 5,900 square miles) of the WLEB that includes 232 HUC-12 digit watersheds partially or completely in Ohio.

Inventory of Municipal Sanitary Sewers A county level approach was used to attain information for municipal sanitary sewer systems. The approach included two phases spanning from 2017 to 2018 for the 19 Ohio counties in the WLEB: Phase I (2017) - Defiance, Fulton, Hancock, Henry, Lucas, Ottawa, Sandusky, Williams, and Wood counties; Phase II (2018) - Allen, Auglaize, Hardin, Mercer, Paulding, Putnam, Seneca, Shelby, Van Wert, and Wyandot counties.

Incorporated municipalities with WWTPs were identified as those with NPDES permits issued by the Ohio EPA (Appendix B). A request for information for the sanitary sewer system was sent to each permitted municipality and county sanitary engineer by email, mail, or phone. Specifically, requests were made for maps showing sanitary sewer lines and/or service areas, with GIS shapefiles as the preferred type of data. If the municipality or county sanitary engineer did not have an available map, a description of the service area was used, such as municipal boundary. For municipalities that did not respond to the request, the sewer service area was assumed to be the municipal boundary.

Inventory of Package Plants Package plants were identified as semi-public and privately owned WWTPs with NPDES permits issued by the Ohio EPA or non-permitted facilities (Appendix C). A request for information on package plants was sent to county sanitary engineers and county health departments by email or phone. Requested information included name, location, treatment equipment, and capacity. Aerial photo maps from Google Earth were used to identify treatment equipment, such as lagoon, extended aeration, and whether sand filters were present.

Creation of Sanitary Sewer Maps All sanitary sewer service areas were mapped using ArcGIS 10.4.1 and individual shapefiles were created for municipal WWTPs and package plants. Sanitary sewer and unsewered area maps were generated using the following steps: • Shapefiles provided by municipalities with sanitary sewer lines were converted to sewer service areas by creating a buffer (400-foot buffer for Wood county and a 200-foot buffer for all other counties). • Shapefiles provided by municipalities showing sanitary sewer service areas were left unmodified. • For municipalities that provided PDF maps or plans, sanitary sewer areas were drawn to best represent the provided maps. • For municipalities that provided verbal or written descriptions, sanitary sewer areas were drawn to best represent the description. • For privately owned package plants that provide service to long-term or permanent residents (e.g., mobile park homes, apartments, campgrounds), aerial photo maps from Google Earth were used to interpret the service areas. • Sanitary sewer parcels were determined as those overlying the sanitary sewer service area. The boundary was reviewed to included parcels with majority of its area within the

8 | P a g e

sanitary sewer service area. Aerial photo maps from Google Earth were used to interpret the sewered parcels, and eliminate undeveloped parcels, such as agriculture fields and wood lots. • Unsewered parcels were determined as all remaining parcels and assumed to be serviced only by HSTS.

Populations and Housing Units Populations and housing units within the unsewered areas were determined using ArcGIS 3.2. Briefly, 2010 U.S. Census data was translated from a Topologically Integrated Geographic Encoding and Referencing (TIGER) housing database into a compatible format and linked with unsewered area shapefiles. The Data Partitioner tool was used to calculate the population and housing units for unsewered areas at the county level and for HUC 12-digit watersheds.

It’s worth noting that within each census block, it is assumed the population and housing units are uniformly distributed. This means that higher values (i.e. overestimates) are likely provided in unsewered areas located adjacent to sewer areas, such as areas just outside of a municipality.

HSTS Nutrient Loads Nitrogen and phosphorus loads for HSTS were estimated using the population in unsewered areas with either nutrient mass or concentration. Both approaches followed a similar equation developed by Ohio EPA (2016) as shown below.

Load based on nutrient mass

LoadHSTS = PopHSTS * NutYield *[percentPopdischarge * DRdischarge + percentPopnondischarge-working * DRnondischarge-working + percentPopnondischarge-nonworking * DRnondischarge-nonworking] where,

• LoadHSTS = Total nutrient load (kg/yr) • PopHSTS = Total population served by HSTS (persons) • NutYield = Annual yield of nutrient per person (0.511 kg-P/person/yr and 3.686 kg-N/person/yr) • percentPopdischarge = Percent of population served by discharging HSTS (32%) • DRdischarge = Nutrient delivery ratio for discharging systems (94%) • percentPopnondischarge-working = Percent of population served by nondischarge-working HSTS (42.5%) • DRnondischarge-working = Nutrient delivery ratio for nondischarge working systems (20%) • percentPopnondischarge-nonworking = Percent of population served by nondischarge-nonworking HSTS (25.5%) • DRnondischarge-nonworking = Nutrient delivery ratio for nondischarge nonworking systems (60%) The nutrient yield was based on values reported by Lowe et al. (2009), these included 0.511 kg- P per capita per year and 3.686 kg-N per capita per year. The percent population using the types of HSTS was obtained from the ODH 2012 survey (ODH 2013), which identified 32% of the

9 | P a g e

population using discharging systems, 42.5% of the population using nondischarging systems working properly, and 25.5% of the population using nondischarging systems not working properly (Appendix D). The nutrient delivery ratio is based on the removal efficiency of the treatment system and used the same values of the Ohio EPA study (Table 1).

Table 1. Nutrient removal and delivery ratios for home sewage treatment systems. Removal Efficiency (%) Delivery (%) System Phosphorus Nitrogen Phosphorus Nitrogen Discharge (all) 6 0 94 100 Nondischarge (working) 80 40 20 60 Nondischarge (nonworking) 40 40 60 60

Load based on nutrient concentration

LoadHSTS = Q * Nutcon * cf * [percentPopdischarge * DRdischarge + percentPopnondischarge-working * DRnondischarge-working + percentPopnondischarge-nonworking * DRnondischarge-nonworking] where,

• LoadHSTS = Total nutrient load (kg/yr) • Q = Annual flow of wastewater by population served by HSTS (million gallons per day, MGD) • Nutcon = Nutrient concentration (10 mg/L for total phosphorus; 40 mg/L for total nitrogen) • cf = conversion factor for kilograms (3.78541) • Remaining parameters are described above

The annual flow value was calculated by multiplying the population served by HSTS and 70.1 gal per capita per day was based on Lowe et al. (2009); the concentration for total phosphorus (10 mg/L) and total nitrogen (40 mg/L) represent the minimum values reported by Gardner et al. (1997).

Package Plant Phosphorus Loads Phosphorus loads for package plants were estimated using information from current NPDES permits and existing records that TMACOG has maintained since the 1980s. Phosphorus load for each package plant was calculated using the equation shown below, which includes average design flow (capacity in gallons per day, gpd), operating period (months per year), and concentration (mg/L). It’s important to note the flow of the package plant is commonly less than the average design flow, so the estimated loads are expected to be higher than the actual load. Package plants were divided into two classes based on flow: < 100,000 gpd or ≥ 100,000 gpd. A total phosphorus concentration of 2.5 mg/L was used for the smaller package plants (< 100,000 gpd) and a concentration of 1.5 mg/L was used for the larger plants (≥ 100,000 gpd). These values were used in the Ohio EPA 2018 study and are based on actual phosphorus monitoring completed

10 | P a g e

at different wastewater treatment facilities (personal communication with Joshua Griffin, Ohio EPA). It’s worth noting that the lower total phosphorus concentrations for the larger package plants (≥ 100,000 gpd) is due to better equipment and operations, and detention time (personal communication with Ryan Gierhart, Ohio EPA).

LoadPKPLANT = Q * Nutcon * cf

Where,

• LoadPKPLANT = annual load for total phosphorus (kg/yr) • Q = average design flow for the package plant (million gallons per year) • Nutcon = total phosphorus concentration (2.5 mg/L for package plants < 100,000 gpd; 1.5 mg/L for package plants ≥ 100,000 gpd) • cf = conversion factor for kilograms (3.78541)

Critical Sewage Areas Critical sewage areas (CSAs) were identified as locations with dense housing units in unsewered areas. Areas where CSAs commonly are located include nonincorporated municipalities, subdivisions, and major intersections. CSAs may be problematic due to potential failure of the wastewater treatment system, such as HSTS or package plant. CSAs were identified by reviewing existing documents and based on discussion with county health departments and county sanitary engineers. Existing documents reviewed were (i) the TMACOG Areawide Water Quality Management Plan “208 Plan”, which includes critical sewage areas already identified for Lucas, Wood, Ottawa, and Sandusky counties; (ii) County Home Sewage Treatment Plans developed by county health districts in 2003-04; (iii) the ODH 2012 Survey, in which county health departments provided estimates for the number of HSTS within designated areas (ODH, 2013). The designated areas by the county health departments were identified as CSAs in this project. Additionally, county maps were reviewed to identify clusters of parcels then aerial photo maps (i.e. Google Earth) were viewed to confirm the presence and approximate number of housing units.

Results

Objective 1 – Sanitary Sewer Service Areas Information for sanitary sewer service areas was provided by 105 of the 126 incorporated municipalities within the study area. Sanitary sewer services areas for the remaining 21 municipalities were assumed to be restricted to the corporate boundaries. A total of 196 active package plants were identified (details for each package plant are provided in Appendix C). Areas serviced by sanitary sewer and package plants are shown in Figure 2 and detailed county maps are provided in Appendix E.

Figure 2. Sanitary sewer service areas in the Ohio portion of the WLEB. The shaded areas are serviced by municipal wastewater treatment plants or package plants.

Objective 2 – Population in Unsewered Areas Eight of the 19 counties were located entirely within the WLEB, which means that only a portion of the remaining 11 counties were included the study area. As expected, higher population densities were observed near municipalities (Figure 3). The highest values observed were in Lucas and Wood counties; Seneca and Shelby counties had the lowest values (Table 2). It’s worth noting that our approach to estimate housing units yielded comparable results as the Hancock County and Wood County Home Sewage Treatment System Plans of 2004 (Hancock County Health Department, 2004; Wood County General Health District, 2004). Whereas the 2004 Plans estimated 7,646 homes for Hancock County and 14,590 for Wood County, our approached estimated 7,433 and 14,290 homes for the two counties, respectively.

Objective 3 - Nutrient Loads from Household Sewage Treatment Systems

County Level Nutrient loads were derived from population, so it was typical the loads increased in counties with higher population. The highest loads were observed in Lucas, Wood, and Allen counties, and the smallest loads were observed in Seneca and Shelby counties (Table 2).

Phosphorus loads estimated based on mass ranged from 0.10 to 9.78 metric tons per annum (mta), and total nitrogen loads ranged from 0.94 to 95.34 mta. In general, nitrogen loads were 10x greater than phosphorus loads. Whereas the estimated phosphorus load based on concentration was 2x greater than loads estimated by mass, the estimated nitrogen loads were similar for both approaches. Phosphorus loads ranged 0.18 to 18.55 mta, and nitrogen loads ranged from 0.98 to 100.28 mta.

Watershed-Level Three of the HUC-8 watersheds are located entirely within Ohio, the remaining seven watersheds extend into areas of Indiana or Michigan, which are not within the scope of this project (Table 3). Therefore, these seven watersheds have an incomplete data set for this project. The Auglaize watershed generated the highest nutrient loads, followed by the Lower Maumee and Cedar- Portage (Table 3). In general, nutrient loadings increased with the area of the watershed. Data for the HUC-12 watersheds that make up the larger HUC-8 watersheds are shown in Appendix A. Estimated phosphorus loads derived from the nutrient mass were approximately half of the load calculated using the nutrient concentration; both methods used for estimating nitrogen loads produced similar values (Table 3).

To determine which of the two approaches (nutrient mass or concentration) used to estimate nutrient loads produced more accurate results for phosphorus, a comparison was made to the recent study completed by Ohio EPA (Ohio EPA 2018). Ohio EPA found that HSTS accounted for 7.7 mta of the total phosphorus load in the Portage River watershed. To directly compare to the Portage River watershed (04100010) delineated by Ohio EPA, data from the following 15 HUC-12 watersheds were compiled: 04100010 01 01, 04100010 01 02, 04100010 01 03, 04100010 01 04, 04100010 02 01, 04100010 02 02, 04100010 02 03, 04100010 02 04, 04100010 02 05, 04100010 03 01, 04100010 03 02, 04100010 04 01, 04100010 04 02, and 04100010 05 02. The cumulative phosphorus load for these HUC-12 watersheds based on nutrient mass was 7.52 mta; the cumulative phosphorus loads for these watersheds based on nutrient concentration was 14.24 mta. Therefore, using the nutrient mass to estimate loads yielded results comparable to the Ohio EPA study. The results of this comparison suggest that the concentration for total phosphorus

15 | P a g e

following primary treatment in a septic system (i.e. effluent from the septic tank) is closer to 5 mg/L than the 10 mg/L used in this study, which was reported by Gardner et al. (1997).

The estimated total nitrogen load using the two approaches (nutrient mass or concentration) yielded similar results: 73.3 and 77.1 mta, respectively, which are comparable to the Ohio EPA stud of 74.5 mta (Ohio EPA 2018). This suggests that a concentration of 40 mg/L for total nitrogen following primary treatment in a septic system is accurate.

Higher nutrient loads were generated in HUC-12 watersheds in the northern portion of the project area, located near Lake Erie (Figures 4 and 5). Highlighted HUC-12 watersheds (Table 4) include those generating a phosphorus load greater than 1.0 mta and nitrogen load greater than 10.0 mta (nutrient load estimates are based on mass). The Cedar Creek-Frontal Lake Erie watershed had the greatest population (6,328) in the unsewered areas resulting in the highest loads for total phosphorus (1.74 mta) and nitrogen (16.98 mta).

As noted above, using census block data assumes the population and housing units are uniformly distributed. Therefore, it is likely the population and housing units are overestimated in the unsewered areas located adjacent to municipalities. For example, Ai Creek includes portions of the Village of Swanton, Heldman Ditch includes portions of the Cities of Sylvania and Toledo, and Preston Run includes a portion of the City of Defiance.

Objective 4 – Package Plants Inventory and Phosphorus Loads A total of 196 package plants were identified within the project area, which generated a total phosphorus load of 8.97 (mta). This estimated load is likely higher than actual because it is based on the plants maintaining their capacity (i.e. maximum load) throughout the assumed operating period (nine or 12 months). Of the 196 plants identified, 145 (74%) had NPDES permits; data for individual package plants are provided in Appendix C. Most (n=104) of the package plants had a capacity less than 10,000 gpd (Figure 6). Ottawa County had the most package plants (n=47) and greatest cumulative phosphorus load (2.66 mta); no package plants were present in portions of Seneca or Wyandot Counties in the WLEB (Table 5).

The Cedar-Portage watershed had the most package plants (n=87) and greatest phosphorus load (3.85 mta) (Figure 7). Many of the plants in the Cedar-Portage watershed are located along the Lake Erie coast in northern Ottawa County (n=15 and on South Bass Island (n=8) and Middle Bass Island (n=5) (Appendix E – Ottawa County Map).

Highlighted HUC-12 watersheds (Table 6) include those with package plants generating a phosphorus load greater than 0.50 mta. Four watersheds were identified with two of them, Crane Creek and Portage River, also highlighted based on the phosphorus load from HSTS (Table 4). Lacarpe Creek-Frontal Lake Erie generated the highest phosphorus load (0.88 mta) and had the most package plants (n=19) (Figures 8 and 9). As previously noted, many of the package plants in the Lacarpe Creek watershed are located along the Lake Erie coast and on South Bass Island and Middle Bass Island.

Objective 5 – Critical Sewage Areas Critical sewage areas (CSAs) were identified in 17 of the 19 Ohio counties in the WLEB; Lucas County had the greatest number (31) of CSAs (Table 7). CSAs that include more than 50 housing units are of concern due to the potential to contribute elevated loadings of nutrients and bacteria

23 | P a g e

to ground- and surface waters. A total of 60 CSAs with at least 50 housing units were identified, with Lucas and Ottawa counties each having 12 CSAs. No CSAs were identified in the portions of Seneca or Wyandot Counties within the WLEB, however, it is likely there are CSAs present in the remaining areas of these counties. Appendix F includes a complete list of the CSAs with estimated housing units as well as county maps showing the locations of the CSAs.

The number of housing units within the CSAs is highly variable; housing units ranged from six to several hundred (Appendix F) with the variability due to the size and location of the CSA. For example, the majority of Middle Bass Island and South Bass Island in Ottawa County were identified as CSAs; each of these islands have several hundred housing units in unsewered areas.

Recommendations

• Identify and map all existing home sewage treatment systems. Although this project provided estimates for population and housing units in unswered areas, actual numbers are needed to assist local stakeholders with decision making. The Ohio Department of Health 2016 sewage regulations (Ohio Administrative Code [OAC] 3701-29) require county health departments to administer an operation and maintenance (O & M) program for HSTS. This requires an assessment of all existing HSTS that should include the determination of type, age, condition, and complexity of each system. While all county health departments started to implement an O & M program in 2016, most counties lack the ability to complete this work in a timely manner. This is due to limitations on funding, staff, and technical resources.

• Connect all housing units and package plants to available and accessible sanitary sewers. The Ohio Revised Code (ORC) 6117.51 states that sewers under the County Commissioners are accessible if within 200 feet of the foundation wall of the structure. Ohio Boards of Health may establish more stringent “accessibility” rules, which the Wood County Board Health has done so by requiring the connection to sanitary sewers within 400 feet.

• Establish total phosphorus limits for all package plants. Majority (104/196) of the package plants identified in this project have a capacity less than 10,000 gpd. However, most package plants in this class (<10,000 gpd) regulated under the NPDES permit program are not required to monitor the final effluent for total phosphorus concentration like larger wastewater treatment facilities (Ohio EPA 2010). To verify the smaller package plants are functioning properly, it is necessary to establish a total phosphorus concentration limits.

• Prioritize critical sewage areas. This project identified 57 CSAs that include more than 50 housing units. CSAs with high densities of housing units are potential sources of nutrients and bacteria to drinking water sources. County health departments and county sanitary engineers should prioritize the importance of CSAs based on the number of housing units and proximity to accessible and available sanitary sewers.
