housekeeping, pollution prevention, and spill prevention and response

In addition to the programs implemented by City departments, the City also maintains an agreement with the Hampton Roads Planning District Commission (HRPDC) to implement portions of the MS4 permit. These programs pertain to the outreach elements in Section I.B.2.j.1.e-f. The HRPDC also coordinates the regional in-system monitoring program in Section I.C.1.

“In the event the permittee is unable to meet conditions of this state permit due to circumstances beyond the permittee’s control, a written explanation of the circumstances that prevented permit compliance shall be submitted to the Department in the annual report.”

Part I.A.4 MS4 Program Resources

“The permittee shall submit to the Department a copy of each fiscal year’s budget including its proposed capital and operations and maintenance expenditures necessary to accomplish the activities required by this state permit. The permittee shall describe its method of funding the stormwater program with the copy of the fiscal year budget.”

The City funds its stormwater management program using stormwater utility fees. The rate structure is the same for all properties in the City and is based on the amount of impervious area on each. Impervious areas are surfaces that do not permit water to penetrate into the ground such as rooftops, concrete or bituminous parking lots, concrete sidewalks, etc. It is this impervious cover that contributes to stormwater runoff. Impervious area is measured in square feet and converted into Equivalent Residential Units (ERUs). The average impervious area for residential properties in the City of Portsmouth is 1,877 square feet, which has been set equivalent to one ERU. All residential properties are billed for one ERU. Commercial properties are billed for the actual amount of impervious cover, which is converted to ERUs. The billing rate for all properties in Portsmouth in FY 2020 was $11.25 per month per ERU.

“Each annual report shall include a summary of actions taken by the permittee to implement Part I.B.2.a)1) and 2) of this state permit.”

The City has continued its program to maintain and monitor structural and nonstructural erosion and sediment control (E&SC) practices to reduce the amount of pollutants in stormwater runoff from construction sites. Site inspections are completed on all projects that disturb 2,500 square feet or more of land area, including demolition projects. Land Disturbance Permits must be obtained for all such projects and an approved E&SC Plan or an Agreement- in-Lieu-of-a-Plan must be obtained prior to any land disturbing activity.

Two full-time Erosion Control Specialists perform routine periodic inspections at all regulated job sites to ensure proper construction methods and proper installation and maintenance of erosion and sediment controls. Inspections are generally conducted once every two weeks and following any runoff-producing storm event. Following a repeat violation, inspections are conducted weekly until compliance is achieved. Please note that since March 2020 and the outbreak of the Covid-19 pandemic, the City has reduced inspection frequencies to two week intervals unless there are mitigating circumstances, e.g. egregious violations, to reduce contact risk for our inspectors and the public. Owners, Contractors, and Responsible Land Disturbers are provided copies of inspection reports when violations occur. On-site meetings are conducted with the responsible parties when necessary, as well as pre-construction meetings before construction begins. The City of Portsmouth also conducts VSMP Inspections at all sites within the City that have land disturbance greater than an acre and that have Construction General Permit coverage.

“Each annual report after program development shall include a list of sites surveyed for floatables, a summary of observations at each site, and a determination as to the effectiveness of the floatables reduction program.”

Outfall Monitoring

The City’s floatable reductions program has continued to operate toward increasing effective removal of waste. Outfall booms have been installed at the five outfall locations listed below. Structures were maintained through the fiscal year with regular cleanings. IC Norcom’s trash boom systems failed twice due to heavy rains and intense flows, possibly combination of higher tides as well. IC Norcom trash booms were repaired after both occurrences, and we have added additional anchors to better secure the booms.

• Morro Boulevard • Lake Shores & Potomac • IC Norcom – Chesapeake Avenue • 2570 Airline Boulevard • Warfield Canal

All infrastructure maintenance and street sweeping programs operated through the reporting year as scheduled. However, outfall surveys were not performed due to limited staffing and decreased work time caused by the COVID-19 pandemic. Public outreach events and training events were also placed on hold until large gatherings are considered safe. The City’s first trainings are scheduled to begin on September 30, 2020 in an outdoor setting with social distancing and mask protocols in place (OSHA LEVEL 2 – HAZARDOUS WASTE TRAINING). The City is in the process of scheduling our trash boom and outfall survey training.

Part I.B.2.l) Dry Weather Screening Program “Each annual report shall include the total number of outfalls included as part of the permittee’s MS4, the number of stations screened during the reporting period, a list of locations upon which the dry weather screening was conducted, the results and any follow-up actions…”

Dry Weather Sampling at seventy-five random sites is conducted to identify potential illicit discharges. Dry Weather samples are tested for the following parameters: FLOW ANALYSIS PARAMETERS TOLERANCE LIMIT (Update per agreement with EPA) pH < 6.0 or > 9.0 Total Chlorine > 4.0 mg/l Hardness (to benchmark Copper) > 3.0 mg/l Total Phenol > 0.026 mg/l Detergents > 0.5 mg/l Ammonia > 2.14 mg/l Potassium > 20 mg/l

As required for the Dry Weather Sampling aspect of our program, at least seventy-five sites were chosen at random, but generally selected in commercial and industrial areas with some coverage in residential areas. These sites were checked for flow and, if observed, the flow was tested for chemical concentrations outside the tolerance limits for the above listed parameters. The screening results are provided in Attachment C.

2. The Hampton Roads Phase I MS4s are still in the first permit cycle for the Bay TMDL, which is likely to be extended, based on the schedule of the other Phase I MS4 permit issuances in the state. The draft Bay TMDL Action Plans are due with the registration statements in December 2020.

3. Virginia Beach shared a few updates with their program. The City is updating their MS4 service area mapping and SWM modeling by June 2021, which they will share with VDOT. The City is revising their design standards to include a 20% increase in the design storms. Looking for water quality benefit add-ons to the numerous flood mitigation projects going on city-wide. ______MS4 Annual Report / City of Portsmouth 49 Fiscal Year 2020 09/30/2020 | V.2

4. Portsmouth noted that they are working on updating their stormwater modeling and coordinating the JLUS project with Chesapeake. The City is working with Ms. Dail of VDOT to resolve some ditch maintenance issues. There was an incidence of an illicit discharge into a VDOT-owned BMP.

5. Chesapeake shared updates regarding their program. They are coordinating the JLUS with Portsmouth. The City is working with USACE to “snag and drag” the Northwest River and working with a contractor to address beaver dams. In the Greenbrier area, the City is developing a BMP Spillway Improvement Plan.

6. Newport News is working on several retrofit projects, including stream restoration, for the third year of the permit.

7. Norfolk has ten or so pond retrofit projects underway. They anticipate meeting their 40% pollutant reduction goal soon.

8. VDOT is looking for municipal partners to achieve further reductions, particularly in the James River.

9. Virginia Beach is the only locality in the process of changing their design standards, though several others are considering doing so. VDOT recently finished a rainfall intensity study with UVA. It is not clear yet if the VDOT design standards will be changed as a result.

10. VDOT is working to update their MS4 mapping tool and requested to work with the localities. They intend to use it to help coordinate maintenance activities. A few localities already provided information on ditches needing attention. BMPs and outfalls are included on the VA Roads data layer, which is publicly available.

11. VDOT has a new IDDE manual and training video.

12. The Central Office of VDOT is managing the HRBT expansion.

12 Student Outreach Environmental Education Lesson Plans

In response to coronavirus safety protocols, public schools throughout Hampton Roads closed for in-person learning in late March. Public schools and parents scrambled to continue education via a virtual platform but few were prepared to operate in a completely online environment. In order to assist teachers and parents in need of content for daily lesson plans, askHRgreen.org crafted nine weeks of environmentally-themed lesson plans for elementary and middle school students. While not targeted at specific Virginia Standards of Learning (SOLs), the lesson plans covered topics such as the water cycle, watersheds, wastewater treatment, Earth Day, waste reduction, drinking water, marine debris, biodiversity and healthy habitats, and sustainable living. Many SOL-based activities were pulled from the previously published Green Learning Guides created by askHRgreen.org for third and sixth grade students. The lessons were well received by teachers and parents in need of new ways to keep their young learners engaged during this detour from a formal education atmosphere.

Environmental Education Mini Grant Program

Supporting environmental education in the classroom continues to be a priority of askHRgreen.org. The Mini Grant program offers all Hampton Roads teachers (K-12), youth leaders, or organizations working with youth mini grants of up to $500 to provide funding for environmentally-themed projects. Providing educators with the funding necessary to bring to life environmental subjects has proven successful over the years but particularly in FY20. For the first time since the mini grant program was consolidated into a single, streamlined askHRgreen program, the entire $10,000 budget was exhausted in one fiscal year. In all, the program supported 21 projects and awarded $10,073 in grant funding. The funded projects reached nearly 8,100 students across Hampton Roads. While funded in FY20, many projects will be implemented in FY21 due to the early school closures caused by coronavirus. Examples of projects funded this fiscal year include pollinator gardens and habitat, meaningful watershed experiences, tap water tastings, native tree plantings, and support for in- school waste reduction programs such as composting and recycling. www.askHRgreen.org 13 Environmental Education Mini Grant Projects

Sedimentation was by far the most common non-compliant attribute found at City owned SWMFs, followed by overgrown vegetation, impacted stone, and presence of trash and debris. This shows a change since the last year of inspections in which many SWMFs found to be overgrown were rehabilitated. A breakdown of deficiency types reported is shown in Figure 1.

Owner Correspondence and Enforcement

Owner notifications were sent prior to inspection activities with maintenance information. The owner was met on-site, if a response was received from the notification letter. Otherwise, the inspection was made on the stated date. Property owners then received a detailed report of findings following the site visit. Enforcement inspection proceeded for those structures found to be non- compliant.

Reinspection activities and guidance for those owners rehabilitating structures have resulted in new compliance for six (6) SWMFs (indicated with asterisks in Table 2), with several more in progress. Multiple SWMF owners have requested extensions for compliance actions due to the COVID-19 pandemic, which the City has accommodated. The City of Portsmouth continues to work with SWMF owners in their efforts to achieve compliance.

Hoffler Creek Bacteria Monitoring Program Update – FY2020

Bacteria monitoring surveys continued on a monthly schedule through fiscal year covered in this report. At each station water samples were obtained, and field observations of water temperature, salinity, and pH were recorded. Water samples were analyzed for presence of Enterococcus sp. and fecal coliforms by the HRSD Central Environmental Laboratory (CEL), VA Laboratory ID 460011. The HRSD CEL remains VELAP/NELAC accredited by the Division of Consolidate Laboratory Services. The results have been summarized below. Monthly average fecal coliform levels ranged from 12.5 - 5,550 MPN/100mL and monthly average Enterococcus sp. Ranged from 12.5 - 731.75CFU/100mL, respectively. Table 1 summarizes the bacteria levels recorded during the reporting year. October 2019 is considered an outlier compared to other months; however, this data is not significant enough to exclude from further analyses. Compared to the survey results of the FY2019 Monitoring Program, the month averages for FY2020 declined significantly.

Discussion and Long-Term Trends The water quality standards for Enterococcus (104 MPN/100ml) and fecal coliforms (43 CFU/100ml) were exceeded at all stations during the fiscal year. These instances occurred both during the warm and cool seasons. The lack of a seasonal trend is a marked difference from previous monitoring periods and may be due to the relatively warm winter experienced. Any correlation to measured water conditions also appears to be absent when combining the past three years of data (Figure 4).

Overall average bacteria levels in Hoffler Creek remained consistent with the previous monitoring results. There was little observed variation between sites during the July 2019 to July 2020 sampling period; however, PHC 000.59 appears to trend lower than the other locations. This may be due to greater tidal influence, as the site is the farthest downstream. Please refer to Figure 3 of the 2016- 2017 Bacteria Monitoring Report for a map of site locations. The spike in bacteria concentrations of October 2019 is also present at all monitoring sites. Though investigators were not able to determine the cause of this event, it seems likely that increased runoff from a previous heavy rain the night prior (almost 1.27 on October 16, 2019) could have caused the increase. This would be consistent with previous observations of increased bacteria concentrations after heavy rains. However, elevated bacteria concentrations found in February 2020 do not appear to be associated with a large rain event. The ultimate cause for increases in bacteria levels still requires further data for analysis. The monitoring program is expected to continue monthly sampling through the following fiscal years.

2020 Inspections Report

INTRODUCTION In 2020 Arcadis assisted the City of Portsmouth in their Municipal Separate Storm Sewer System (MS4) permit compliance by leading the necessary inspections of the City-owned stormwater drainage structures located adjacent to and/or receiving flow from businesses classified as high-risk runoff facilities.

The stormwater structures and system inspected were those receiving runoff from locations classified as Priority 4 and Priority 5 facilities. A total of 17 facilities were inspected, including four (4) Priority 4 sites and fourteen (13) Priority 5 sites. The sites were inspected and documented by one (1) City of Portsmouth stormwater inspector and two (2) Arcadis stormwater engineers.

Prior to the inspections, digital field inspection forms were created in a mobile databased application (Fulcrum) to reduce paper and redundancy as well as create an organized and consistent format. Arcadis produced GIS inspection maps based on the City of Portsmouth’s planimetric and stormwater network data to provide an overview and understanding of the drainage profile for each site. In addition to the digital inspection forms as the GIS maps, OSHA approved Personal Protective Equipment (PPE), traffic cones, manhole pick(s), dry erase site identification placard, first aid kit, flashlight(s) as well as mobile phones for inspection photos and Fulcrum App completion.

All inspections where performed on dates considered to be “dry weather” (dry weather defined as a minimum of 72 hours following any rainfall event totaling a 24-hour total of 0.1” depth). The purpose of the dry weather inspections is to determine dry weather flow and identify potential illicit discharge draining from the identified sites. A detailed summary of the field inspection procedure is provided on the City of Portsmouth MS4 Program Industrial and High-Risk Facilities technical memorandum.

INSPECTION RESULTS During the 2020 inspection year, the most common issue identified among the sites inspected was varying amounts of litter and trash debris, ranging from minimal to significant amounts of trash, documented in and around the structures of concern. The sources of the trash documented in each inspection could not be definitively linked to the associated facilities, but it was noted that removal of the trash build-up could improve drainage capacity and stormwater quality for each site.

Other frequent issues noted during inspections was the presence of stagnant water or dry weather flow within the inspected structures. The amount of standing water varied by site, ranging anywhere from approximately 1” to over 12” in the larger capacity systems. In the structures where dry weather flow was observed, there were no cases of any discernable component of the flow originating from the

facilities being inspected. Since each site was only inspected during dry weather, stormwater runoff was not considered to be an active component of the water noted in the system. The most likely source of flow in these instances was determined to be groundwater infiltration upstream of the inspected structure from between pipe joints or defects and through pipe to structure connections.

The tables below summarize the findings from the 17 facility inspections performed. Detailed findings of each inspection can be found in the attached site inspection reports

FOLLOW UP DISCUSSIONS WITH THE CITY Upon completion of the 17 site inspections listed in Tables 1 & 2 above, there were no significant items of concern found. However, Arcadis personnel identified five (5) sites where the inspection findings revealed evidence of potential illicit discharge that could require remediation. Typical findings for these sights included the presence of chemical odors, visible oil sheens, buried/obscured infrastructure, and GIS connectivity discrepancies. However, there was no evidence of illicit discharges originating from the five facilities inspected. These sites and the respective inspection findings were presented to the City in June 2020 for follow up discussions. Upon receipt, City crews were dispatched to perform various maintenance activities at the indicated sites. The City provided Arcadis with a summary of the activities performed and findings noted by City crews.

The results of these follow up discussions with the City are summarized in Table 3 below. A detailed description of the follow up action and recommendation, if any, for each site be found in the attached site inspection reports.

FACILITIES TO BE CONSIDERED FOR REMOVAL FROM INSPECTION LIST Leading up to and during the field inspections several locations were identified to have either been vacated, or the nature of the actual business activities have changed to a non-Industrial and High-Risk status and no longer qualified for an inspection. These locations are summarized below.

Four industrial facilities were identified during this project as candidates for removal from the Industrial and High Risk Facilities list. In some cases, the businesses are registered to residential homes and the appearance of any industrial activities was not present. In other cases, the recorded business no longer occupies the corresponding address.

206 Sandpiper Rd: Nottingham Window and Door

This business address is in a residential neighborhood. Although there is a detached garage, there are no apparent indications of any industrial activities taking place at this location.

4435 Winchester Dr: Chris’s Auto Electric

This business address is in a residential neighborhood. Upon receipt of the owner notification letter, the owner contacted Arcadis to mention his business is mobile in nature and conducted from his work van, not his home. Additionally, the owner has retired, and his business was only re-registered with the State Corporation Commission (SCC) and City of Portsmouth for the 2020 calendar year to allow the business to close out 2019 tax/accounting issues before closing permanently.

1011 Queen Street: All Star Auto Repair

This location is no longer occupied by a business. The building appears vacant with no commercial operations taking place on site.

2200 High Street: High Street Amoco

This address no longer has a building or business located on site. The parcel currently contains grass, landscaping, sidewalk and park benches. It appears to have been cleared to allow for the Martin Luther King Jr Freeway.

Regional Water Quality Monitoring Program Annual Report

Introduction In order to characterize nutrient and sediment concentrations related to urban stormwater, the six Phase I MS4 localities within Hampton Roads, in partnership with the U.S. Geological Survey (USGS) and the Hampton Roads Sanitation District (HRSD), created a regional stormwater monitoring network. This network is dual-purposed, simultaneously addressing local water quality issues and fulfilling MS4 permit requirements, while providing useful data to support Chesapeake Bay Program modeling efforts. This report was developed to fulfill the requirements stated in the Phase I localities’ MS4 permits. The Chesapeake Bay Program’s watershed model is responsible for estimating loads of total nitrogen (TN), total phosphorus (TP), and total suspended solids (TSS) throughout the Bay watershed. While monitoring began with the non-tidal network (NTN), primarily covering rural areas, there are no calibration stations within the Coastal Plain, nor stations that reflect urban centers, and therefore no verifiable loading rates of these constituents. USGS now has multiple sites to inform future versions of the Bay model, representing a range of percent impervious land cover (Fig. 1). In 2018, localities agreed to another five-year commitment of monitoring to obtain a long-term data Figure 1. Representation of USGS monitoring stations series. By providing high frequency and within the Chesapeake Bay watershed, including the high quality data through the USGS non-tidal network (NTN), based on percent impervious land cover. quality control and quality assurance framework, the Hampton Roads region will be well-represented with accurate estimates of loading rates for future phases of the model. Towards the latter part of FY20, the region was impacted by COVID-19, forcing many to work from home, however the monitoring program was not impacted and samples continued to be obtained and analyzed.

Monitoring Network The six Phase I MS4 localities (Chesapeake, Hampton, Newport News, Norfolk, Portsmouth, and Virginia Beach) participate in the Hampton Roads Regional Water Quality Monitoring Program (RWQMP). Each locality has two monitoring sites, draining land between 30 and 300 acres with no tidal water influence, representative of three types of urban land uses (high-density residential, single- family residential, and commercial/industrial), and ranging between 36% and 80% imperviousness (Fig. 2; Table 1). Site selection Figure 2. Locations of the 12 water quality monitoring stations, overlaid on land cover, in was also based on the goal of having very few, if Hampton Roads, VA. any, best management practices (BMPs) upstream of the sampling area. By characterizing the range in loadings that are typical of a given land-use type that do not yet have BMPs implemented, variability can be assessed within land use types, and meaningful comparisons can be made between the three dominant land use types in the region. This should significantly enhance the understanding of how management activities can be directed efficiently in the future.

Operation of the monitoring network is the joint responsibility of USGS and HRSD. Data collection is supervised by the USGS Virginia Water Science Center to ensure that data quality meets the requirements established by USGS. Discrete sample collection and analysis plus system maintenance are conducted by HRSD’s Central Environmental Laboratory (CEL) while data analysis, interpretation, and reporting are conducted by USGS. All 12 stations collect real- time, high frequency data including flow (stage, velocity, and discharge), turbidity, specific conductance, and water temperature. Discrete samples for nutrients and sediments are taken during storm events over a range of flows and for quarterly baseflow sampling. Nutrient concentrations consist of measurements of TN, total Kjeldahl nitrogen (TKN), organic nitrogen, nitrate + nitrite, ammonia + ammonium, TP, and orthophosphate. Sediments are measured as TSS.

Monitoring Protocols Each station is equipped with a continuous flow meter, a water quality sonde for continuous water quality monitoring, a refrigerated automated sampler for the collection of stormwater water quality samples, an internal data logger for recording and storing all measured values, a satellite telemetry unit to transmit data hourly, a power system supporting all components (AC power with battery backup), and a ruggedized housing that protects all equipment (Fig. 3). Continuous flow is measured at 5 minute intervals and flow meters are connected to the data logger and satellite Figure 3. Ruggedized housing and components telemetry system to provide data in near real present at each stormwater monitoring station. time. Instruments are operated in accordance to manufacturer guidance, and USGS guidance (see http://water.usgs.gov/osw/pubs.html). Continuous water quality monitors measure water temperature, specific conductance, and turbidity and are operated in accordance to standard protocol (Wagner et al. 2006). Discrete sampling for nutrients and sediment are triggered by the datalogger when stormflow conditions exist (as indicated by flow and water quality conditions). Samples are retained in the refrigerated sampler (≤ 6°C) until retrieved by HRSD field staff. Samples are retrieved within 24 hours of collection, transported in coolers (≤ 6°C), and delivered to the laboratory for preservation and analysis. The analytes measured have defined laboratory methods within 40 CFR Part 136 and TN is calculated as the sum of TKN and nitrate + nitrite. Detailed standard operating procedures for nutrient and sediment analysis are maintained at HRSD’s CEL and are available upon request. All data collected for this monitoring program, including continuous time series data and discrete sample data, is retained in the USGS National Water Information System (NWIS) and made publicly available online via NWISweb (http://waterdata.usgs.gov/HRStormwater). Continuous data from the flow meter and water quality monitors are transmitted via GOES

satellite hourly and uploaded directly into NWIS via automated processes. These data are made publicly available on NWISweb within minutes of the hourly transmission. Discrete sample data is entered into the Laboratory Information Management System (LIMS) at HRSD. These data are electronically transferred monthly to USGS for entry into NWIS, at which time they are publicly accessible via NWISweb.

Results Monitoring station installation began in April 2015 with all stations online and collecting data by December 2016. Between July 1, 2019 and June 30, 2020, across 28 storm events, over 480 event- triggered samples were collected for nutrients (Fig. 4). The intent of the program is to quantify loads during non- storm and storm events, to compare baseline loads to high intensity or Figure 4. Total sampling events per quarter for each station prolonged rainfall events. During the FY between July 1, 2019 and June 30, 2020. 20 sampling season, two major rain events were captured. Of note, during Hurricane Dorian (9/8/19), key flow measurements were made and 39 samples were collected. During an intense April storm (4/30/20), 31 samples were collected. Monthly samples are collected at each station on a fixed schedule regardless of hydrologic condition to capture storm versus baseflow characteristics. These samples can be used to characterize spatial and temporal patterns, load contributions from discharging groundwater, and trends in concentration. In past years, we observed that the greatest amount of stormflow is associated with stations that have the greatest amount of impervious surface within the watershed. Commercial sites had the greatest amount of impervious surface compared to other land use types with turf grass and tree cover. As watershed imperviousness increases, the proportion of flow from storm runoff increases, and the proportion of flow from groundwater decreases. Impervious cover also increases the speed and volume of runoff and limits groundwater recharge. In the Hampton

Hampton Roads Planning District Commission September, 2020

Roads network, groundwater accounts for 5-55% of total flow. In past years, we reported that even though commercial sites generated more stormflow per acre, TN concentrations were greater in the single-family and high-density residential land use compared to commercial land use and that normalized annual TN yields (lbs/acre) were slightly higher on commercial landscapes but not significantly different between land use types on average. These trends haven’t changed and this year’s analysis focuses more on nutrient composition and comparisons with other monitoring networks. The monitoring networks compared comprised of the Chesapeake Bay’s non-tidal network (NTN), a network in Atlanta and in Fairfax County, all run by USGS. Comparisons are inclusive of baseflow and stormflow across the years in which they were sampled. For the Hampton Roads network, this data is inclusive of all sampling since 2016. TN yields in Hampton Roads are comparable across the monitoring networks, with no significant differences observed among the median concentrations (Fig. 5A). Hampton Roads TN samples are composed primarily of organic N while inorganic N (in the form of nitrate) dominates in Fairfax County’s A B monitoring network (Fig. 5B). This may be related to streamflow characteristics as slow-moving waters, as in the Hampton Roads network, increase residence time of allochthonous inputs, and/or C D there is an absence of organisms that process colored particulate organic matter (CPOM). Nitrate yields in Hampton Roads are comparable to Atlanta and significantly lower than Fairfax Figure 5. Total nitrogen (A), nitrate, total phosphorus, and County and the NTN (Fig. 5B). orthophosphate yields (lbs/acre) across various monitoring networks. This may be due to a lack of septic infrastructure. As has been seen in studies in Atlanta, nitrate concentrations can be high in areas that have high geographic densities of septic systems (Hoghoogi et al, 2016). The Hampton

Hampton Roads Planning District Commission September, 2020

Roads network does not have many, if any, septic systems within the drainage areas of these urban monitoring systems. Total phosphorus yields in Hampton Roads are higher than the NTN and ATL and comparable to Fairfax County (Fig. 5C). Orthophosphate yields in Hampton Roads are significantly higher than other networks (Fig. 5D). A larger proportion of TP yields in Hampton 3- Roads are composed of PO4 compared to Fairfax County (which is comprised primarily of particulate P). This could be a function of source types, the Hampton Roads region is mostly sandy soils which have a low sorptive capacity. Additionally, sediment yields in Hampton Roads are significantly lower than all other networks (Fig. 6). Coastal Plain watersheds have a more limited source of sediment and the topography does not generate the energy required to Figure 6. Sediment yield (lbs/acre) across various tidal monitoring networks. mobilize as much sediment as compared to the Piedmont.

Hampton Roads Planning District Commission September, 2020

Comparisons were made to look at the composition of nitrogen in baseflow (dry weather conditions) versus stormflow (wet weather conditions). The nitrate load is equally generated during baseflow and stormflow while TN, primarily comprised of organic nitrogen, is transported more during stormflow

Organic N and other forms of hydrologic source, baseflow or stormflow for the Hampton particulate bound N is generally Roads monitoring network. thought to be mobilized by overland runoff with sources from atmospheric deposition, pet waste, leaf litter, lawn clippings, and excess fertilizer. Orthophosphate loadings occur during periods of runoff as orthophosphate is washed off the land surface (Fig. 7). TP is transported by overland flows rather than groundwater sources and approximately 2/3 of loads are from particulate bound P (not shown in figure). The vast majority of suspended solids (sediment and course particulates such as decomposing leaf litter) are mobilized by storm runoff, the proportion transported during low flows may be algae and/or fine particulate organic matter. The monitoring network results were also looked at to determine how much precipitation generates loads. On average for this network, there are 250 “dry” (< 0.1 inches), 40 “wet” (0.25 – 1.0 inches), and 8 “extreme” (>1.5 inches) days per year. The percent of annual loads for TN doesn’t vary as a function of dry, wet, or extreme precipitation events (Fig. 8A) but more inorganic nitrogen is generated during dry times (Fig. 8B). This makes sense as inorganic nitrogen is a large component of the baseflow, which is primarily groundwater. However, organic nitrogen is generated during wet and extreme events (Fig 8C), suggesting BMP measures can be put in place to mitigate the transport of organic nitrogen to receiving waters if necessary. It is yet to be determined, however, if this type of organic nitrogen is bioavailable to organisms in the surface waters in the lower portion of the Bay. Typically, the lower portion of the Bay is limited by nitrogen and inorganic nitrogen is the preferred source of nitrogen for algal growth (Fisher et al., 1992). There is research on-going linking certain harmful algae growth to

Hampton Roads Planning District Commission September, 2020

mixotrophy, or the ability of algae to prefer organic and inorganic nitrogen as their nutrient source (Hofmann et al., submitted, Mulholland et al. 2009). For TP (Fig. 8D), orthophosphate (Fig. 8E), and TSS (Fig. 8F), the majority of the loads are mobilized during wet and extreme events. BMPs that can capture these events would be ideal as they are capturing all of the relevant constituents necessary to limit eutrophication in the lower part of the Bay. Many urban BMPs are designed to mitigate nutrients and sediment conveyed during periods of moderate rainfall, suggesting further research needs to be done to adapt BMPs for higher rainfall events or allow for the capture of larger stormwater events in the urban landscape.

While it is too soon to evaluate trends over time, patterns are emerging relating total constituent yields to precipitation. As expected, wetter years result in higher yields for TP, TSS, and TN (Fig. 9). Precipitation patterns decreased over the course of the monitoring program, and the smoothed line fit of the annual yields appeared to decrease as well. However, the data is still extremely variable and assessing trends over only 4 years is not typical.

Discussion

The Regional Water Quality Monitoring Program has almost five years of data collected and each year of analysis confirms findings from the previous year while also prompting new questions and allowing for better comparisons with other urban networks. Annual discharges as well as nutrient concentration variability among land use types is still evident. As shown in the past, generally, constituent concentrations are greatest at sites with single-family and high- density residential sites compared to commercial sites, in contrast, annual yields normalized to drainage size tend to be higher at commercial sites. This variability is likely a function of percent imperviousness and may be due to runoff volume rather than the concentration of inputs. It is likely that high inorganic N found at residential sites is simply getting diluted during stormflow events. As more data accumulates, we can continue to compare yields from runoff volume to baseflow, or groundwater. This monitoring program is unique in that it captures dry weather baseflow that is primarily groundwater comprised of inorganic N. Other monitoring programs run by USGS capture the baseflow of natural streams. Runoff or stormflow in the Hampton

Roads network is mostly comprised of organic N and storms can account for nearly 50% of the total annual flow in the monitoring system. Organic N also makes up the bulk of the TN pool and is transported more during wet and extreme events. Therefore, it may be valuable to understand the bioavailability of the organic N fraction in the receiving waters of the stormwater system. Different types of organic N, whether naturally formed, from runoff, or as a byproduct of wastewater treatment, can be bioavailable in estuarine communities, but it depends heavily on the type and composition of organic N (Seitzinger et al. 2002, Filippino et al. 2011). Organic N in this system could be from algae formed inside the pipe, resuspension of material as it travels through the system, or from outside sources washed from lawns and impervious surfaces. These types of bioassays are costly and a consistent laboratory method has yet to be developed, however project partners are looking for ways to explore finding funding for this research. Once bioavailability is determined, managing for organic N on commercial sites for stormflow versus inorganic N on residential sites could be a valuable strategy. For management purposes, approved BMPs do not have load reduction estimates for specific forms of nitrogen, they only account for bulk nutrient removal. However, some practices could be better at removing organic N versus inorganic N. For example, any BMP that is associated with settling of particles could remove more organic N and any BMP that performs denitrification (converting nitrate to nitrogen gas) would remove more nitrate. Many BMPs could fall into these categories however (living shorelines, floating treatment wetlands, oyster reefs, etc.), and more research is needed to determine efficiencies associated with nitrate or organic N removal and how to maximize those reductions. Evaluating BMPs that are able to reduce nitrogen during more extreme events and considering alternatives, like water storage, is a future research need that could be addressed within the Chesapeake Bay Program partnership. Like TN, TP loads are generated at higher yields from commercial sites and are also being transported more during storm events as opposed to the baseflow. Also like TN, with less imperviousness there is less particulate and dissolved organic P. Inorganic P can come from a variety of sources, like fertilizer, mineralization of organic materials, and desorption from soil particles. Looking at bioavailability of TP constituents versus TN constituents would also help managers decide on strategies that may reduce TN versus TP. While BMP reduction efficiencies in Virginia are tied to TP, production of algae in receiving waters in the Coastal Plain are likely due to increased TN, as it is the limiting nutrient. Understanding better the sources of organic P,

whether or not it is tied to particles or dissolved, and its bioavailability in relation to TN would be helpful to understand for management purposes. Conversely, TSS did not vary from site to site. In comparison to other monitoring programs across the state conducted by the USGS, TSS concentrations are much lower in the Coastal Plain. This monitoring program is allowing us to see a more holistic picture of baseflow and runoff for the region and the importance of TN versus TP across different land uses. It is also allowing for comparisons of other urban networks to provide better insights in the types of nutrients entering the Bay from the Coastal Plain. We are also starting to see trends in annual yields in relation to annual precipitation, while acknowledging the extremes that occur and produce the majority of the loads. Through continued monitoring and research, we can get closer to calculating runoff ratios based on impervious surfaces, investigate and apply management strategies that target the bioavailable nutrients, and inform decision-makers using the best available science for the region. It is the goal of this monitoring program to factor in storm variability, baseflow, and land use type over an extended period of time to establish demonstrable loading rates in the Coastal Plain. This will provide valuable data to a future version of the Chesapeake Bay watershed model and contribute to current calibrations of the Phase 6 model. Over the course of the next few years, localities will continue to collaborate with USGS and HRSD to collect data and evaluate loading rates over the long term.
