Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 3

Section 1: Minimum Control Measures #1 ― #6, Activities in Year 2

MCM1 – Public Education and Outreach (Permit Sec. Part I.E.1.g(1) – (2))

Due to the restrictions in place because of the COVID-19 pandemic, the in-person outreach activities that we usually conduct or take part in during springtime (e.g., Fest, student field trips) could not happen during the second half of Year 2. However, during that time we changed course to deliver some excellent web-based educational materials and curricula for the general public and school students.

Rivanna Stormwater Education Partnership - The County continues its fruitful collaboration with other local MS4 permit holders – the City of Charlottesville, the University of Virginia, and the Rivanna Water and Sewer Authority – in implementing education and involvement efforts through the Rivanna Stormwater Education Partnership (RSEP). The Thomas Jefferson Soil and Water Conservation District (TJSWCD) serves as the partnership’s coordinating body. The partnership website is http://www.rivanna-stormwater.org/, which received a major upgrade during the reporting year. RSEP met seven times during the reporting period to discuss and organize initiatives and share information pertaining to stormwater stewardship and permit compliance. Educational outreach and planning activities conducted by the partnership during Year 2 are listed in the table below.

RSEP members regularly consult and update the public education and outreach plan that is shown within the County’s 2018-2023 MS4 Program Plan. The strategies in the plan and those activities implemented in Year 2 address one or more of the plan’s three high-priority stormwater issues: runoff volume reductions, potential runoff pollutants, and TMDL impairments (bacteria, sediment, nitrogen, phosphorus).

Meaningful Watershed Experiences – The County, through an ongoing contract with TJSWCD, continues to provide watershed education to County public school students, staff, and parents through the Meaningful Watershed Education Experience (MWEE). During the Fall 2019 semester, 525 Albemarle County Public School 4th graders and 135 adults took part in MWEEs at Camp Albemarle on the Mormons River. The experience included a demonstration of benthic stream sampling and a tutorial about watersheds using the Enviroscape watershed model. As alluded to above, the spring MWEE field trips were cancelled. However, TJSWCD staff successfully continued delivering educational watershed materials to County students via their schoolteachers, but through online means.

Presentation on Native Riparian Plants, Flood Control with Dams – On Sept 19, 2019 County MS4 staff gave a presentation to approximately 40 non-environmental County staff about the benefits of native plants in riparian areas for infiltration and erosion protection, as well as flood control with dams.

Future MCM1 Activities – During Year 3, we anticipate conducting educational activities like those described above. Additionally, we have already worked through the RSEP partnership to distribute a Love Your Watershed stormwater message on a utility bill and have printed several thousand Love Your Watershed stickers, to be distributed throughout the year. RSEP members also plan to install pet waste bag stations at trailheads where currently there are none. We will likely still be limited in our ability to hold in-person activities during the remainder of Year 3, but we will find creative ways to continue reaching out to the public about stormwater stewardship in our community.

MCM2 – Public Involvement and Participation (Permit Sec. Part I.E.2.f)

Public Input on MS4 Program (Permit Sec. Part I.E.2.f(1)) – During this reporting year, County MS4 staff received a total of 30 stormwater/drainage alerts or complaints from the public. Staff responded to all of these with a site visit to evaluate and resolve each specific situation as appropriate. Also, the RSEP illicit discharge reporting hotline received 5 reports from the public, one of which was for an issue within Albemarle County’s MS4 area (see the section on MCM#3 for more detail).

MS4 Program Webpage (Permit Sec. Part I.E.2.f(2)) – Albemarle County’s website was recently completely redone (after Year 2). The new webpage where the public can report a stormwater problem or learn about the County’s MS4 program and other water resources topics, is located here: https://www.albemarle.org/government/facilities-environmental-services/environmental- stewardship/water-resource-protection

Public Involvement Activities (Permit Sec. Part I.E.2.f(3) – (5)) – The following stormwater and watershed activities conducted in Year 2 involved the participation of members of the public and were supported by Albemarle County staff and/or funds.

• Funding for RCA Water Monitoring Program – For many years, the County has helped fund the Rivanna Conservation Alliance’s (RCA) community-based stream monitoring program (formerly called StreamWatch). This program is certified Level III by DEQ; the data collected by this program is incorporated into DEQ’s water quality testing program. With the help of trained volunteers, RCA conducts extensive benthic monitoring throughout the Rivanna basin, as well as bacterial monitoring in the Charlottesville and Albemarle MS4 areas.

• Volunteer Maintenance of Streamside Trails – Albemarle County Parks and Recreation involves the public in the maintenance of trails alongside streams and rivers. Streamside trails increase public interest and involvement in water stewardship. o Metric: # of volunteer hours o Value: 42 hours

• Albemarle Conservation Assistance Program (ACAP) – This program assists property owners in Albemarle County with financing and technical assistance for the installation of new water quality best management practices. It serves as match to the state-wide Virginia Conservation Assistance Program funding. The program is administered by TJSWCD. o Metric: # of BMPs installed o Value: 10 BMPs o Metric: County funds for ACAP o Value: $32,000

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 6

• Climate Action Planning – Albemarle’s Climate Action planning process has included a robust community involvement component. Many components of climate action planning overlap with watershed stewardship and water pollution (e.g., tree planting, flood mitigation). During the reporting year, the public was invited to provide input on the draft Phase 1 Climate Action Plan. There was immense success getting feedback from the community through a questionnaire, as well as individual letters submitted to the County. o Metric: # of comments received o Value: over 750 o Metric: # of participants o Value: 381

• Rivanna River Basin Commission conference & general support – The Rivanna River Basin Commission holds a small conference for local partners and members of the public each year. This meeting allows for knowledge sharing and input from participants on local watershed needs. In Year 2, Albemarle County provided a location for the conference and provided general operating support to RRBC, as it does most years. County elected officials and staff participated in the conference. o Metric: # of conference participants o Value: ~30 o Metric: Annual funds provided to RRBC for general support o Value: $6,210

• Landowner Involvement in Stormwater Basin Retrofits – Although stormwater capital projects are currently postponed due to high bid prices and COVID-19 budget impacts, County staff have worked closely with owners and property managers of two privately owned stormwater facilities in order to gain support for stormwater retrofit projects involving the creation of bioretention and constructed wetlands. County staff have educated property owners and managers regarding the aesthetic, maintenance, and environmental benefits of stormwater retrofits and have received the easements and support required to construct these projects. o Metric: # of property owners / managers reached o Value: ~10

Future MCM2 Activities – During FY 2020 the County will engage the public through the following efforts:

• Benthic and Bacteria Sampling by Community-based Stream Monitoring Program – To satisfy data needs and continue our engagement with the community, Albemarle will continue to support Rivanna Conservation Alliance’s volunteer-supported water monitoring program. We will also continue contracting with RCA to perform both benthic and bacteria sampling at streams in and near our MS4 area.

• Public Input on Stream Buffers – Albemarle will continue to solicit community advice around the re- drafting of our stream buffer protection rules.

MCM3 – Illicit Discharge Detection and Elimination (Permit Sec. Part I.E.3.e)

Map & Information Table (Permit Sec. Part I.E.3.e(1)) – Albemarle County staff continuously update the storm sewer system map and outfall information table for our MS4 area. Any known changes to MS4

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 7

stormwater infrastructure that occurred on or before June 30, 2020 have been updated in our geographic information system. No changes have been made to the MS4 area boundary during this reporting year.

Albemarle County does not own and maintain a traditional, interconnected storm sewer system, as is typically the case in cities. Public roadways in the County – and the drainage infrastructure within the rights-of-way (ROW) – are operated by Virginia Department of Transportation (VDOT). Most of the infrastructure outside of VDOT right-of-way is located on private property. The County is responsible for infrastructure on its own properties – including school and park properties – and within public easements on private properties.

While most of the drainage infrastructure within the County’s MS4 jurisdictional area is not actually maintained by the County, staff has been locating and mapping all infrastructure to the extent that we can. We have mapped approximately 90% of stormwater infrastructure within our MS4 area, irrespective of ownership. The map below shows an example of our progress to date.

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 8

Above: Storm sewer infrastructure (red) in Albemarle MS4 area.

Outfall Screening (Permit Sec. Part I.E.3.e(2)) – Per a continuing contractual arrangement with the TJSWCD, and over a period of more than a decade, the County has been conducting an IDDE survey of all perennial and intermittent streams in and around the County’s MS4 and other developed areas. Every year, TJSWCD staff conduct dry-weather screening of a subset of the stormwater outfalls along those streams. The survey includes updating storm sewer outfall locations in our mapping system and conducting a visual screening for signs of illicit discharges. Other details of the survey protocol are described in the Program Plan. During the Year 2 reporting period, 51 outfalls were surveyed in the MS4 area (see map below).

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 9

Above: Outfalls surveyed in MS4 area during Year 2.

Illicit Discharge Summary (Permit Sec. Part I.E.3.e(3)) – No illicit discharges were identified during the annual dry weather outfall screening. However, County MS4 and Fire Marshal staff respond to reports by the public of suspected illicit discharges through the RSEP illicit discharge hotline and/or discover them while in the field. Additional reports or inquiries from the public are received through the County phone system or are forwarded by colleagues. A record of reported suspected illicit discharges and other types of inquiries and complaints is maintained in the Environmental Services Division’s files.

During this reporting period, the County investigated four potential or actual illicit discharges in the MS4 area. Details of each are shown in the table below:

MCM4 – Construction Site Stormwater Runoff Control (Permit Sec. Part I.E.4)

Albemarle County’s construction site stormwater runoff program is implemented in accordance with Part I.E.4.a (1) of the MS4 General Permit. Albemarle County has been authorized by DEQ as a local authority of the Virginia Erosion and Sediment Control Program (VESCP) and the Virginia Stormwater Management Program (VSMP). Property owners preparing to engage in land disturbing activities must obtain a permit from the Community Development Department prior to the commencement of land disturbance. Land disturbing activities are also regulated by Albemarle’s Water Protection Ordinance. The standards and specifications for erosion and sediment control are no different than State regulations, except the County is more stringent in at least four respects:

• the land disturbance threshold for small construction activities is 10,000 square feet, as opposed to one acre • denuded areas must be stabilized with permanent vegetation within nine months after commencing land disturbing activity (with caveats and opportunities for extensions) • the zoning ordinance limits the use of fill or waste areas to one year • a 100-foot vegetated buffer on qualifying streams must be developed and maintained in perpetuity where a regulated land disturbing activity occurs

Inspections and Enforcement Actions (Permit Sec. Part I.E.4.d(2) – (3)) – The following table is a summary of inspections and enforcement actions for regulated land-disturbing activities in Albemarle County during the reporting year.

MCM5 – Post-Construction Stormwater Management (Permit Sec. Part I.E.5.i)

Per VSMP and County requirements, Albemarle periodically inspects permanent privately and publicly- owned stormwater management facilities (SMFs). There are approximately 1,200 SMFs in the County;

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 12

approximately 700 are located within the MS4 area. The locations of SMFs are maintained in a GIS and other data are maintained in a linked database.

Private SMF Inspections (Permit Sec. Part I.E.5.i(1)) – The table below summarizes our inspection activity of private SMFs this reporting year:

Inspection records for private stormwater management facilities in Albemarle County MS4 area (07/01/19 – 06/30/20)

Number of facilities in MS4 area 679 Number of inspections in MS4 area during 305 reporting period Outcome = "compliant" 168

Outcome = "repairs needed" 47

Outcome = "pending" 80

Public SMF Inspections (Permit Sec. Part I.E.5.i(2)) – The County owns/operates a total of 89 SMFs throughout the County. All those that fall within the MS4 area (38) were inspected by County staff at least once during the reporting year.

Significant Maintenance/Repairs of Public SMFs (Permit Sec. Part I.E.5.i(3)) – In addition to routine maintenance of County-owned stormwater facilities (e.g., mowing, trash removal), some of these facilities received more significant maintenance and repairs during the reporting year. No significant maintenance or repair projects were undertaken in Year 2.

Construction Database Submittal (Permit Sec. Part I.E.5.i(4)) – Albemarle County electronically reported SMF information through the Virginia Construction Stormwater General Permit (CGP) database for land disturbing activities for which coverage under the General VDPES Permit for Discharges of Stormwater was obtained in accordance with Part I.E.5.f of the MS4 General Permit.

BMP Warehouse Submittal (Permit Sec. Part I.E.5.i(5)) – Albemarle County electronically reported BMPs on September 30, 2020 using the DEQ BMP Warehouse in accordance with Part I.E.5.g of the General Permit.

MCM6 – Pollution Prevention & Good Housekeeping (Permit Sec. Part I.E.6.q (1))

Through our Environmental Management Policy, Albemarle County is committed to environmental compliance, pollution prevention, and continual environmental improvement both within and outside our MS4 area. Many of the efforts related to the County’s implementation of an Environmental Management System (EMS) satisfy requirements under this stormwater permit.

During the reporting period, Albemarle County Local Government was certified at the Platinum level and Albemarle County Public Schools was certified at the Gold Level in the Virginia Municipal League’s “Go

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 13

Green Virginia” challenge which – a statewide competition for localities to showcase their various pollution prevention-related programs. Additionally, we maintain E3 level certification in the DEQ’s Virginia Environmental Excellence Program (VEEP) for the Department of Facilities and Environmental Services, Department of Parks and Recreation, and Public Schools fence lines.

Operation Procedures Summary (Permit Sec. Part I.E.6.q(1) – The EMS program constitutes the written procedures for daily good housekeeping and pollution prevention activities. The EMS includes the following standard operating procedures (SOPs), which are included as attachments to the Program Plan.

• Safer Chemical Procedure • Integrated Pest Management • Underground Storage Tank Management • Spill Prevention and Response • Hazardous Conditions

Of the SOPs listed above, the Safer Chemical Procedure is the only one that was modified during the reporting year. Changes include: requiring warning signage at approved sites immediately prior to spraying pesticides/herbicides and for at least 24 hours after; reporting approved waivers on a website; and clarification for incidental pesticide/herbicide use by employees.

Stormwater-related highlights of the EMS program include:

• All waste materials from our facilities are disposed of properly and contained in covered dumpsters. Dumpsters at local government and school locations are in good repair and are required to be cleaned on a regular basis by waste haulers. Custodial staff is trained annually on good housekeeping, spill prevention, spill reporting, and outdoor storage of materials. • A contractor agreement is in place for the majority of our maintenance, grounds, and custodial contracts that states that any contractor doing work in/on our facilities will not dump anything down a storm drain. All contractors, including painters, general construction contractors, and carpenters, must sign this document before any work is conducted. • The County has a Safer Chemical Management Policy which mandates the use of green certified cleaning agents, sharply restricts the use of pesticides, and promotes the use of bio-based pesticides when there is no alternative to the use of pesticides. • The County Public Schools and Local Government have developed an Integrated Pest Management program for indoor and outdoor pest/weed control. This minimizes the amount of pesticides and herbicides used on school properties and subsequently discharged in stormwater. • Albemarle Public Schools has developed a program to save water and reduce unnecessary runoff by adjusting schedules and irrigation amounts based on monitored rainfall. • Weekly inspections are performed at our permitted vehicle wash outfall. An interior automated wash bay reduces number of vehicles being washed at the exterior bay. • Maintenance and custodial personnel at fuel site locations are trained on cleanup measures and emergency response.

High-Priority Facilities & SWPPPs (Permit Sec. Part I.E.6.q(2)-(3)) – Albemarle County has no facilities identified as “high-priority facilities”, as defined in the General Permit.

Evaluation of MS4 Program Implementation (Permit Sec. Part I.D.2.e)

The preceding sub-sections summarize Year 2 activities and progress associated with each minimum control measure. MS4 programs are designed to be adaptive to changes in requirements, local and regional conditions, available resources, and the state of best practices. As such, the professionals responsible for implementing this program have and will, as needed, make adjustments to policies, procedures, or activities to improve the effectiveness in meeting permit requirements and the more fundamental goal of improving the health of local and regional waters. We believe that no formal changes are needed to Albemarle County’s original MS4 Program Plan.

Albemarle County MS4 Program (2018 – 2023) Year 2 Annual Report 15

Section 2: Chesapeake Bay TMDL Action Plan Activities (Permit Sec. Part II.A.13)

Per requirements of the MS4 General Permit, the County has prepared and submitted a Phase II Chesapeake Bay TMDL Action Plan, which was submitted on October 31, 2019. Additionally, the General Permit requires that Albemarle County annually report control measures implemented during the reporting period, the cumulative progress toward meeting the Chesapeake Bay TMDL compliance targets for nitrogen (TN), phosphorus (TP), and sediment (TSS), and control measures that are expected to be implemented during the next reporting period.

Chesapeake Bay TMDL - New Control Measures Implemented (Permit Sec. Part II.A.13.a-b)

New control measures were not installed during the reporting period. However, the County’s stream restoration projects previously had not previously been properly recorded in the BMP warehouse. These projects were submitted to the BMP warehouse on September 30, 2020.

Chesapeake Bay TMDL - Grandfathered Projects Update

The Chesapeake Bay TMDL Guidance Document (Guidance Memo No. 15-2005, released May 18, 2015) states that “permittees should address reductions for grandfathered projects that initiate construction after the initial Action Plan submission in the Chesapeake Bay TMDL Action Plan section of future annual reports submitted for the reporting period in which the grandfathered construction began.” County staff have identified two additional grandfathered projects which initiated construction after the initial Action Plan submission and before July 1, 2019, but these projects were erroneously not reported previously. Pollution reduction totals for grandfathered projects is included in Attachment A.

Chesapeake Bay TMDL - POC Accounting Update (Permit Sec. Part II.A.13.c)

The MS4 permit requires permittees to provide – as part of this Annual Report – progress made towards meeting the required cumulative reductions for TN, TP, and TSS using the final design efficiency of the BMPs. The table below summarizes the total pollutant of concern (POC) reduction requirements and credits accumulated by Albemarle County through June 30, 2020. While new control measures were not implemented by the County in the reporting period, the County’s total progress toward reduction in TN, TP, and TSS loads have been impacted via accounting for an additional grandfathered project with excess water quality credit available.

TMDL credit calculation for these projects and control measures are calculated pursuant to the Chesapeake Bay TMDL Guidance Document, using methods discussed in Section 4.2 (New Sources) and Section 4.3 (Grandfathered Sources) of Albemarle County’s approved Chesapeake Bay TMDL Action Plan. Calculations for grandfathered projects and newly implemented control measures are included in Attachment A.

Chesapeake Bay TMDL - Future Projects Update (Permit Sec. Part II.A.13.d)

Section II.A.13.d of the MS4 permit requires the County to provide a list of control measures that are planned to be implemented during the next reporting period. The project presented in the table below was previously planned for implementation in the reporting period ending on June 30, 2020. However, fiscal impacts from the COVID-19 pandemic have resulted in a budget freeze within Albemarle County local government, and, as a result, the project has not yet been constructed. The ultimate construction date is currently unknown.

The County’s Phase II Chesapeake Bay TMDL Action Plan provides descriptions of additional stormwater retrofits and stream restoration projects that are being planned by the County. As stated in the plan, the County reserves the right to modify the practices and projects described and to add, remove, and/or substitute practices and projects for the ones described in this annual report.

Section 3: Local TMDL Action Plan Activities (Permit Sec. Part II.B.9)

Albemarle County MS4 staff recently updated its “Combined Local TMDL Action Plan: Sediment TMDL for the Rivanna River and Bacteria TMDL for the Rivanna River Mainstem, North Fork Rivanna River, Preddy Creek and Tributaries, Meadow Creek, Mechums River, and Beaver Creek Watersheds” during the reporting period (April 2020).

The construction of the most recent restoration practices that the County has implemented to reduce a significant amount of sediment pollution were completed just prior to the start of the reporting year (e.g., RiverRun and Chapel Hills stream restoration projects). However, many of the bacteria pollution reduction strategies listed in the Local TMDL Action Plan are ongoing and were employed in the MS4 area during the reporting period. The following table lists some of the activities, listed by bacteria source, conducted in Year 2 that correspond to our Local TMDL Action Plan.

Activities for Bacteria Reduction in Year 2, By Source Activities Strategy Description Domestic Pets: Leash ordinance A new County ordinance (Sec. 4-225) was adopted in Year 2 that requires that dogs be on a leash when not on the owner’s property. This will increase the likelihood that an owner will notice when his/her dog defecates and thus increase the likelihood that she/he will pick up and dispose of the pet waste. Pet waste The County’s parks have receptacles into which dog owners are asked to receptacles at parks dispose of their pet’s waste. Pet waste bags are also provided at designated dog parks. Urban Wildlife/Birds: Signage against County-owned stormwater wet ponds in the MS4 area are posted with feeding wildlife signs prohibiting the feeding of wildlife. This is to reduce the potential numbers of birds and other animals that would otherwise be attracted to those ponds. Trash removal from At one of its stormwater wet ponds that receives a high volume of trash stormwater ponds from an adjacent shopping center in the MS4 area, the County has installed a floating boom to collect floatables. The trash is removed regularly throughout the year, reducing the trash load downstream – a potential attractant of wildlife to streams. Illicit connections or illicit discharges: Detection and Albemarle County has conducted video assessment of the County’s storm elimination of sewer systems, which will help identify cross-connections with the sanitary leaking sanitary sewer system. MS4 staff will also start using enhanced illicit discharge sewers and cross- detection and outfall screening methodologies to identify sewage leaks, connections starting in FY2021.

Other Sources: Septage treatment Rivanna Water and Sewer Authority accepts septage from RVs, for recreational motorhomes, campers, and charter buses at its wastewater treatment vehicles facility at no cost. This reduces the likelihood of raw septage being improperly disposed of in waterways or on land.

Enhanced Many of the County’s stormwater management facilities are maintained in maintenance of such a way as to provide a functional ecosystem that can process bacteria stormwater from wildlife and stormwater sources. This includes strategies to maintain facilities plant diversity, reduce invasive species, and provide for floodplain and wetland functionality.
