INTRODUCTION

Background The Stormwater Management Plan (SWMP) is designed to limit, to the maximum extent practicable, discharge of pollutants into the stormwater system. This plan consists of established procedures and best management practices (BMPs) to achieve the goals outlined in the Federal Clean Water Act and the State of Arizona Stormwater Regulations.

Facility Description The Phoenix VA Health Care System (PVAHCS) is located at 650 E. Indian School Road, Phoenix, Arizona, 85012. The campus consists of a 38.5-acre property with approximately 22 buildings.

Outfalls There are no outfalls from PVAHCS campus. Stormwater on the PVAHCS campus is collected in storm drain inlets and conveyed through a vast network of storm drainpipes to various catchment basin throughout the campus. Stormwater is also collected in numerous drywells located throughout the campus. See Appendix A for stormwater and drywell maps.

Water Quality Concerns & Priorities Some of the biggest potential water quality concerns for these waters involve sediment loads from disturbed areas; fertilizers and pesticides from landscaping areas; and oil and grease from roadway and parking areas.

Historic Properties and Threatened or Endangered Species Although construction on the medical center campus started in 1949. On November 2, 2013, The Arizona State Historic Preservation Office determined that Carl T. Hayden Medical Center of PVAHCS was not eligible for the historic registry. In addition, there are no endangered nor threatened species within one mile of the medical center.

ROLES and RESPONSIBILITIES:

a. Medical Center Director: The Director has overall responsibility for compliance with the stormwater regulations and the implementation of this plan.

b. Capital Projects/Engineering: Project Engineers are responsible for:

1. Updating stormwater map(s) with any changes.

2. If required, communicating necessary stormwater permitting requirements to contractors who perform work that impacts stormwater.

3. Ensuring contractor has applied for and obtained the appropriate Arizona Department of

Environmental Quality (ADEQ) Construction Activity General Permit for Stormwater prior to the project breaking ground.

i. See http://www.azdeq.gov/AZPDES/CGP for further Construction Activity General Permit for Stormwater information.

4. Evaluating compliance with the contractor's stormwater runoff control program as part of their construction site final inspection program, document concerns, and ensure abatement.

c. Contractors working at PVAHCS are required to follow permit and minimize the discharge of pollutants through the entire life of the project.

d. The Construction Committee and/or the GEMS manager are, if necessary or when applicable, responsible for further reviews/surveys/inspections of construction activities on campus. The Stormwater Construction Site Inspection Form is used as a tool to assist with site reviews and inspections (see Appendix B for the Stormwater Construction Site Inspection Form).

http://www.azdeq.gov/AZPDES/CGPFor

STORMWATER PROGRAM ENFORCEMENT

Enforcement Illicit connections and/or discharges that lead to the stormwater system are prohibited. Only stormwater is to enter the stormwater system. Dumping or disposal of materials into the stormwater system is prohibited.

To minimize discharge of pollutants by way of installation, implementation, and/or maintenance, contractors working at PVAHCS are to follow the stormwater control measure requirements contained in their contract submission documents. Violators of the facility's permit must cease and desist illicit discharges and spills and/or abate such discharges.

PVAHCS’ VA Police Department will enforce violations of stormwater pollution on PVAHCS property. First time offenders will be issued a United States District Court Violation Notice (USDCVN) under the VA Regulation 1.218 (b) Schedule of Offenses and Penalties for Disorderly Conduct, which tends to impede or prevent the normal operation of a service or operation of the facility. In the event of a repeat offense, the case will be forwarded to the United States Attorney's Office, District of Arizona and the Regional Counsel for further review and guidance.

STORMWATER and UTILITIES MAPPING PVAHCS has developed comprehensive facility stormwater and drywell location maps located in Appendix A. Maps are updated as new information becomes available.

STORMWATER MANAGEMENT

Pollutants and Pollutant Sources The table below identifies some, but not all, pollutants and pollutant sources that have the potential to impact receiving water from PVAHCS. The Stormwater Management Plan aims to avoid, minimize, or eliminate any associated potential adverse effects.

Possible Pollutants Possible Pollutant Sources

- Pesticides, herbicides, fungicides, and fertilizer

- Cleaning chemicals

- Concrete

- Sediment

- Landscaping debris

- Litter and trash

- Paint

- Gasoline and diesel fuel

- Hydraulic oil and lubricants

- Biohazards, sewage

- Lab chemicals

- Boiler, cooling tower, and other building system chemicals

- Fuel storage tanks

- Used oil storage drums

- Maintenance buildings and yards

- Poorly maintained vehicles

- Material storage areas

- Hazardous material storage and transfer areas

- Parking lot and road maintenance

- Landscape maintenance

- Waste storage and transfer areas

- Construction projects

- Cross contamination with sanitary sewer

- Building and equipment maintenance

- Pet waste

Best Management Practices PVAHCS will reduce pollutant discharges to the maximum extent practicable to protect water quality by implementing Best Management Practices (BMPs). The Phoenix VA Medical Center utilizes surface retention and dry wells to collect and convey on-site stormwater runoff to groundwater. There is essentially no runoff from the PVAHCS site. Current and future efforts to reduce pollutants, mitigate accidental discharges, and thereby diminish stormwater runoff pollutants include:

1. SPCC Plan. Should an accidental discharge occur, the Spill Prevention, Control, and Countermeasures (SPCC) Plan is a detailed document describing potential fuel oil related spill hazards with preventative spill measures and described cleanup procedures. The SPCC includes:

a. Monthly and periodic inspections of:

i. Underground Storage Tanks (UST)

ii. Aboveground Storage Tanks (AST)

iii. Elevator Hydraulic Oil Reservoirs

iv. Transformers (these contain mineral oil for cooling)

b. Record keeping and record retention of the above inspections

c. Material Transfer Checklist with detailed procedures and protocols

d. Annual Emergency Spill training is required for employees who have the potential to be involved in an accidental release cleanup

e. Specific notification protocols

f. Emergency spill kits (aka: Spill Release Response Inventory) are maintained

2. Maintenance of Equipment. Preventative maintenance greatly reduces risks for an accidental release.

a. UST monthly, annual, and triennial maintenance is performed as required and specified by

Arizona Department of Environmental Quality (ADEQ). In addition, USTs are monitored 24/7 with a leak detection system known as Veeder Root. The Veeder Root system is monitored by boiler plant personnel who are present 24/7. Maintenance of the Veeder Root system is implemented to ADEQ’s standards.

b. AST monthly and annual maintenance requirements are performed as specified by Maricopa County.

3. Periodic Audits/Inspections. The Phoenix VA Medical Center is frequently inspected by Federal, State, and Local agencies:

a. Federal level –

i. Independent audits commissioned by the VHA perform comprehensive environmental audits on a 5-year basis. Physical infrastructure, policies, procedures, maintenance records, and disposal protocols are all scrutinized. Reports of these audits are submitted to local and national leadership.

ii. Environmental audits are performed by our regional managers on an annual basis.

Physical infrastructure, policies, procedures, maintenance records, and disposal protocols are all examined. Final reports are submitted to local and national leadership.

b. State Level - Arizona DEQ inspects PVAHCS for:

i. UST management and regulation compliance

ii. Hazardous Waste management and regulation compliance

c. Local Level – The City of Phoenix inspects PVAHCS for:

i. Sewer regulation compliance

ii. Stormwater regulation compliance

d. Internally – Our maintenance services inspect the following monthly:

i. Underground Storage Tanks (UST), inspections performed by Maintenance & Operations

ii. Aboveground Storage Tanks (AST), inspections performed by Maintenance & Operations and Grounds Crew.

iii. Elevator Reservoirs, inspections performed by Maintenance & Operations

iv. Transformers, inspections performed by Maintenance & Operations (executed quarterly)

4. Policies. PVAHCS sustains written policies which are updated when a substantive change is needed or at minimum every five years. Policies that apply to stormwater discharges include:

a. Hazardous Waste Management:

i. The hazardous waste storage area is inspected weekly

ii. All stored hazardous waste is kept on secondary containment pallets and, when appropriate, kept in flammable cabinets

iii. Hazardous waste is stored in compatible containers

iv. Hazardous waste is shipped off site frequently and long before reaching EPA storage time limit requirements

v. Continuous monitoring of the entire facility by VA Police

b. Hazardous Spill Response and Clean-Up

c. Slug Control Plan

5. 24/7 Police presence on the campus: the VA Police are often the first to uncover fluid spills (such as engine oil or coolant leaks) and play an integral role in spill discovery as they make rounds around the facility. Already equipped with spill kits, the Police are well prepared when they encounter a spill. Spill kits contain pads and granules to absorb a spill. Once a spill is addressed, the Grounds Crew is then notified to collect the used cleanup debris and dispose of it properly.

6. Grounds Crew. As the name suggests, the Grounds Crew is a dedicated group of employees devoted to the maintenance and upkeep of our facility’s outdoor features. The Grounds Crew:

a. Possess street sweepers to ensure our parking lots, on-campus roads, entrance gates, and driveways are free from dirt and debris. The sweepers are used on a predetermined schedule and are also deployed when special circumstances require.

b. Safeguard our stormwater retention ponds by keeping them clean and free from garbage

c. Perform regularly scheduled grounds cleanup and maintenance

d. Play an integral role in spill discovery

e. Confront any irregular polluting events that need attention (such as engine oil or coolant leaks)

f. Retain spill cleanup supplies to be used when vehicle oil/coolant leaks occur on campus

REVIEW PRACTICES

In addition to BMPs, there are also practices established which take place prior to, during, and post construction activities. These practices include Preconstruction Review, Stormwater Runoff Control During Construction Activities, Periodic Inspections, and Post-Construction Stormwater Management.

Preconstruction Review Procedures Preconstruction review procedures which include the following:

1. Review of site design, planned operations at the construction site, planned construction BMPs, and proposed post-construction BMPs.

2. Plan and design of future projects with engineering methodology to address the 100 year 2-hour rain event due to the finite footprint of this Campus.

3. Apply the National Environmental Protection Act (NEPA) process which includes consideration for the potential water quality impacts.

4. Consider low impact design and green infrastructure.

5. Identify priority construction sites.

6. Prepare a Notice of Intent (NOI) for the appropriate permit that will be submitted to the regulating authority (ADEQ). The assigned Project Engineer will be responsible for Construction General Permits which endeavor to address:

a. Construction activities that disturb 1 or more of acres of land.

b. Construction activities that will disturb less than 1 acre but are part of a larger common plan of development or sale that will ultimately disturb 1 acre or more.

c. Support activities from temporary plants or operations set up onsite to produce concrete, asphalt, or other materials exclusively for the permitted construction project.

Refer to ADEQ’s website http://www.azdeq.gov/AZPDES/CGP for more information.

7. When applicable, the assigned Project Engineer shall analyze the project site as it exists before the project starts. The Project Engineer shall verify with the local, state, and federal regulatory agency for the project site to ensure the correct land coverage runoff coefficient “C" value is used for the pre-development condition. The local jurisdiction's standard for "pre-developed" shall be in lieu of the EISA Section 438 requirements. The Project Engineer shall use an approved hydrologic modeling program to study the entire site's drainage system and the amount of flow leaving all the outlets on the project site.

8. Opportunities for Low Impact Design (LID) will be evaluated and encouraged.

9. PVAHCS requires a Stormwater Pollution Prevention Plan (SWPPP) to be submitted to PVAHCS and approved prior to beginning construction as part of the contract submission documents.

10. Records of these reviews will be available for a period of five (5) years. The preconstruction review procedure will include the following:

a. Review of site design, planned operations at the construction site, planned construction BMPs, and proposed post-construction BMPs.

b. The National Environmental Protection Act (NEPA) process includes consideration of the potential water quality impacts.

c. Evaluation of low impact design and green infrastructure.

d. Identification of priority construction sites.

Stormwater Runoff Control During Construction Activities (Same as below?)

Capital Projects utilizes the following documents to implement and enforce stormwater runoff pollutant reduction efforts originating from on-campus construction sites:

1. Section 438 of the Energy Independence and Security Act (EISA), which provides guidance on Implementing the Stormwater Runoff Requirements for Federal Projects.

2. VA Site Development Design Manual — February 2013. Chapter 6: Stormwater Management.

a. Stormwater attenuation

b. Pre-developed flow rates

c. Post-developed flow rates

d. Stormwater quality

e. Stormwater management plan

f. Best management practices

3. VA Master Specifications Guide, Section 01 57 19, Temporary Environmental Controls.

4. Construction specifications for activities that will disturb one or more acres of land will include a requirement for the contractor (Contractor, architect, or engineer) to develop, implement maintain and enforce a stormwater runoff control program to minimize or eliminate pollutant discharge. Program requirements include:

a. Minimize the amount of disturbed area and protect natural resources. Stabilize sites when projects are complete, or operations have temporarily ceased.

b. Protect slopes on the site of the construction activity.

http://www.azdeq.gov/AZPDES/CGP

c. Protect storm drain inlets and armor all newly constructed outlets.

d. Use perimeter controls at the site.

e. Stabilize entrances and exits at the location of the construction activity to prevent off-site tracking.

f. Inspect stormwater controls at consistent intervals.

g. Control wastes, including but not limited to, by discarded building materials, paints, fertilizers, concrete washout. chemicals, litter, and sanitary wastes.

h. Records of these reviews will be available for a period of five (5) years.

i. PVAHCS Project Engineer will evaluate compliance with the contractor's stormwater runoff control program as part of their routine construction site inspection program, document concerns, and ensure abatement.

Periodic Inspections

1. After the project is underway, the assigned PVAHCS Project Engineer will verify the provisions of the SWPPP are implemented, followed, and maintained. To fully complete this task, the assigned Project Engineer will follow existing contract provisions for the inspection and enforcement of SWPPPs at construction sites. The inspection procedure will include the following:

a. Monthly or bi-weekly inspections (as determined by the Construction Safety Committee) conducted on all sites requiring a SWPPP as defined above and be documented.

b. Inspections will be conducted during all phases of construction: before land disturbance during construction activities and following active construction.

c. Based on inspection findings, all follow up actions will be performed (e.g. reinspection, enforcement action) and documented in the project record.

d. Notification and verification procedures for determining final stabilization and authorizing removal of temporary measures.

e. If a swale or retention basin is installed as part of the project, Engineering Projects Section is responsible for updating the as-built plans.

Post-Construction Stormwater Management

1. After construction activities are complete, PVAHCS will ensure that new development and redevelopment sites that disturbed one or more acres of land, including sites less than one acre that are a part of a common plan of development design, install, and maintain post-construction stormwater controls that reduce or eliminate the discharge of pollutants front the site, i.e., swale or retention basin.

2. An inventory of all post-construction structural stormwater control measures installed and implemented at new development and redevelopment sites will be maintained.

3. Master Specifications Guide, Section 01 57 19, Temporary Environmental Controls, also requires that upon completion of the project and after removal of all debris, rubbish, and temporary construction materials, the Contractor shall leave the construction area in clean condition satisfactory to the VA. Cleaning shall include off the station disposal of all items and materials not required to be salvaged, as well as all debris and rubbish resulting from demolition and new work operations. Authorization of the Final Payment is dependent on this item.
