CITY OF OREM STORM WATER MANAGEMENT PLAN OVERVIEW Last Reviewed: September 13, 2019
PURPOSE
This document presents the City of Orem’s Storm Water Management Plan (SWMP). The City of Orem originally applied for coverage in 2003 and was granted permit number UTR090014. This management plan is a major revision meant to satisfy the requirements of the State for the period of 2016-2021. The plan has been updated to limit the discharge of pollutants, as much as is practical, to the City of Orem’s Storm Water System. This Plan was prepared to guide the City in planning, funding, and implementing a comprehensive program for addressing current and future regulatory and policy requirements for managing storm water runoff. The purpose of the Storm Water Management Plan is to comprehensively address how to meet the many different but related regulations, adopt plans, programs, and policies that affect urban storm water runoff, flooding, and protect the environment, including water quality. The goal of the SWMP is to provide the City of Orem the basis for establishing effective rules, regulations, and guidelines that will reduce the potential for storm water damage to the environment, to the citizens of Orem, to public and private property, and to protect human, animal, and aquatic life. Storm water regulations developed by the Utah Division of Water Quality require the operator of a regulated MS4 community to develop a program that:
• Prevents or reduces the amount of storm water pollution generated by municipal operations and conveyed into receiving waters by identifying and implementing appropriate control measures and setting measureable goals. • Train employees on how to incorporate pollution prevention and good housekeeping techniques into municipal operations.
SWMP COORDINATION Agency: City of Orem, Public Works Department Contact: Mr. Christopher R. Tschirki, Public Works Director UPDES Number: UTR090014
STAFFING AND RESOURCE ALLOCATIONS
Responsibility for implementation of the storm water management program is divided between different groups and organizations within the City. The group responsible for each task is stated in each section of this document.
Permit Requirement 2.3.2.2 MS4 Location Description and Map The City of Orem (City) has a population of approximately 96,000 and encompasses approximately 18.5 square miles. The City is located in the center of Utah Valley, 40 miles south of Salt Lake City. It is surrounded by Provo to the south and east, Vineyard to the west, and Lindon to the north (see Figure 1-1).The City is situated between the Wasatch Mountains, the Provo River, and Utah Lake.
Storm Water Management Plan -2016- i STORM WATER MANAGEMENT PLAN OVERVIEW
Figure 1-1: Map of Orem’s location
Permit Requirement 2.3.2.3 Water Quality Concerns The City operates and maintains a municipal storm water system that consists of thousands of sumps (class v injection wells), several miles of pipe, and numerous detention basins. With these assets, the City has some unique challenges as it addresses its storm drainage system. Most of the City is located on highly permeable sands and gravels that comprise the Orem bench. The City has taken advantage of the highly permeable soils for management of storm drainage and relies heavily upon sumps for storm drainage disposal.
There are currently more than 3,600 sumps within the City, of which 1,771 are located on public property. Runoff is directed into these sumps, which discharge directly to the underlying soils. Even though the use of sumps is an acceptable method for runoff disposal, untreated storm drainage runoff
Storm Water Management Plan -2016- ii STORM WATER MANAGEMENT PLAN OVERVIEW
can eventually reach the underlying groundwater aquifers, which supplies the culinary water to the City and a number of other communities in Northern Utah County.
Concern about the impact of sumps on groundwater quality, long-term maintenance of sumps, and areas with existing storm drainage problems has motivated the City to evaluate current storm drainage disposal practices and to create a long-term storm water master plan for the City.
STORM WATER POLLUTANT SOURCES AND ENVIRONMENTAL IMPACTS
The table below outlines the most common potential pollutants that any MS4 could generate. These pollutants can harm human health, degrade water quality, damage aquatic habitat, and seriously impair ecosystem functions.
Pollutant Common Source Impacts on Water Quality Sediment Construction sites, vehicle/boat Sediment is a common component of storm water. Sediment can washing, agricultural sites be detrimental to aquatic habitat for fish and plants, transportation of attached oils, nutrients and other chemical contamination, and increased flooding. Sediment can transport other pollutants that are attached to it including nutrients, trace metals, and hydrocarbons. Sediment is the primary component of total suspended solids (TSS), a common water quality analytical parameter.
Nutrients Fertilizers from agricultural Nutrients are often found in storm water. These nutrients can (Phosphorus, operations, lawns and gardens; result in excessive or accelerated growth of harmful algal Nitrogen livestock and pet waste, blooms, reduced oxygen in the water, changes in water Potassium, decaying grass and leaves, chemistry and pH. In addition, un-ionized ammonia (one of the Ammonia) sewer overflows and leaks. nitrogen forms) can be toxic to fish.
Hydrocarbons Vehicle and equipment fluid Oil and grease include a wide array of hydrocarbon compounds, (Petroleum leaks, engine emissions, some of which are toxic to aquatic organisms at low Products, pesticides, equipment cleaning, concentrations. Some of these pollutants are toxic to humans Benzene, leaking fuel storage containers, and wildlife at very low levels. Toluene, Ethyl fuel spills, parking lot runoff benzene, Xylene)
Heavy Metals Vehicle brake and equipment Metals including lead, zinc, cadmium, copper, chromium and wear, engine emissions, parking nickel are commonly found in storm water. Metals are of lot runoff, batteries, paint and concern, as they are toxic to aquatic organisms, can wood preservatives, fuels and bioaccumulate, and have the potential to contaminate drinking fuel additives, pesticides, water supplies. cleaning agents
Toxic Chemicals Pesticides, herbicides, dioxins, Pesticides have been repeatedly detected in storm water at toxic (Chlorides) PCBs, industrial chemical spills levels, even when pesticides have been applied in accordance and leaks, deicers, solvents, with label instructions. As pesticide use has increased, so too have concerns about the adverse effect of pesticides on the environment and human health.

Pollutant Common Source Impacts on Water Quality Debris/Litter/ Improper solid waste storage Typically resulting from an urban environment, industrial sites Trash and disposal, abandoned and construction sites, trash and floatables create an aesthetic eye equipment, litter sore in waterways. Risk of decay product toxicity. Risk of aquatic animal entrapment or ingestion and death.
Pathogens Livestock, human, and pet Bacteria and viruses are common contaminates of storm water. (Bacteria) waste, sewer overflows and There are human health risks due to disease and produces toxic leaks, septic systems contamination of aquatic life.
The following table lists some lesser-known pollutants that can be found in most urban storm water runoff, yet are harmful to the environment.
Pollutant Potential Health Effect Source Chlorine Used as an additive to water to control microbes. Used in swimming pools, drinking water disinfection, etc.
Arsenic Skin damage or problems with Erosion of natural deposits; runoff from orchards, runoff circulatory systems, and may have from glass and electronics production wastes. increased risk of cancer Beryllium Discharge from metal refineries and coal-burning factories; discharge from electrical, aerospace, and defense industries. Cadmium Kidney damage Corrosion of galvanized pipes; erosion of natural deposits; discharge from metal refineries; runoff from waste batteries and paint. 2, 4-D Kidney, liver, or adrenal gland Runoff from herbicide used on row crops. problems
PAHs Potential risk to aquatic life Sources of PAHs are numerous and include municipal (Polycyclic and industrial effluents and discharges. Combustion Aromatic products from transportation, power generation, and Hydrocarbons) coking processes are significant manmade sources. Other potential sources include manufactured gas plants, wood treatment facilities, and smelters as well as from coal-tar- based pavement sealants.
Storm Water Management Plan -2016- iv STORM WATER MANAGEMENT PLAN OVERVIEW
To reduce these pollutants the following six minimum control measures) in the areas of (1) public education and outreach, (2) public participation and involvement, (3) illicit discharge detection and elimination, (4) construction site runoff control, (5) long-term storm water management in new development and redevelopment (post-construction storm water management), and (6) pollution prevention and good housekeeping. Implementation of these 6 control measures is presented in subsequent chapters and includes Standard Operating Procedures (SOPs) and Best Management Practices (BMPs). The SOPs and BMPs are intended to meet the current needs of the City and will be changed as needed.
Permit Requirement 2.3.2.5 Modifications to City Ordinance The City of Orem tracks changes to the City’s ordinance. The date of the enactment of each ordinance along with dates associated with amendments to each ordinance can be found in the City’s code.
Permit Requirement 3.1.1.1- 3.1.1.2 does the City Discharge to a 303(d) Waterbody? Under Section 3.1 of the Small MS4 General UPDES Permit, Permit Number UTR090000, it states, “Permittees must determine whether storm water discharge from any part of the MS4 contributes to a 303(d) listed waterbody.”
Orem City currently discharges into Utah Lake, which is listed on the 303(d) listing as an impaired waterbody. Total Dissolved Solids (TDS), total Phosphorous, and PCB in fish tissue are all concerns for Utah Lake. The status associated with these pollutants are low to medium. A draft TMDL was published in 2007, however the TMDL has not been adopted. Once adopted the City will implement regulations necessary to be in compliance with these standards.
Additionally, the City discharges into the Provo River, which has been designated as, impaired for OE Bioassessment. This is a condition that requires the monitoring of the health data of benthic macroinvertebrates, fish and periphyton. The State has not determined a cause for concern in the biosassessment, but if a TMDL is published for this stretch of the Provo River, the City intends to follow the recommendations in the TMDL.
Permit Requirement 3.2.1 Nutrient Reduction In order to protect the receiving water bodies, design BMPs for new or redeveloped sites are required. Developers must design BMP’s to treat storm water with a goal of reducing pollutants in the receiving water bodies. BMP’s should address removal of phosphorous, total suspended solids, and other target pollutants. Proposed BMPs will be evaluated by City staff to verify selected BMP’s are addressing pollutant removal.

Chapter 1
MCM 1: Public Education and Outreach on Storm Water Impacts
The permit requirements for Public Education and Outreach on Storm Water Impacts can be found in Section 4.2.1 of the permit. This section also incorporates tasks intended to meet the Nutrient Reduction Section of the permit found in Section 3.2. A copy of the General Permit for Discharges from Small MS4s can be found at DWQ’s Website. The permit outlines in general the following requirements: 1. The MS4 must promote behavior change of the public to reduce water quality impacts associated with pollutants in storm water runoff and illicit discharges. This is a multimedia approach targeted to specific audiences. The four audiences are: (1) residents, (2) institutions, industrial and commercial facilities, (3) developers and contractors (construction), and (4) MS4-owned or operated facilities. (4.2.1) 2. Target pollutants and pollutant sources and their potential impacts relating to storm water quality. (4.2.1.1) 3. Provide and document information given to the four focus audiences. 4. Provide documentation or rationale as to why particular programs were chosen for its public education and outreach program
The City of Orem has implemented tasks to meet the requirements of this MCM, which are summarized in this section:

Among these are: • WaterWatch Newsletter: This informational newsletter features articles that are generally targeted at residents living in the City of Orem. In the past, it was mailed quarterly; however, responses to the newsletter have declined through the years. This has been made a digital publication and is available on Orem’s Storm Water webpage. Additionally, it is publicized on the City’s social media pages. • Information Booths at Community Events: The City has participated in several community events and plans to do so in the future. Most notably the City has set up a booth at its annual Summerfest. Booths at these events have included two models. We also distribute literature and promotional items that discuss storm water quality issues and feature our storm water hotline number. • Storm Drain Markers: The City has established a program to mark all public storm drain inlets with curb markers. Through the assistance of several Eagle Scout candidates’ projects, the utility has marked all City-owned storm drain inlets. During the permit period between 3/1/2016 and 2/28/2021, all City storm water facilities will be inspected. At the time of inspection, storm drain inlets will be re-marked as necessary by stenciling or by replacement of storm drain markers. Maintenance of these markers will be scheduled as needed. This maintenance may be accomplished by City employees or by community volunteers. Many existing markers read, “Do not dump, drains to drinking water”. Those installed in the future will have the City’s Storm water Hotline posted on them. • Social Media: The City often uses Facebook, Twitter and YouTube to maintain a presence in social media. We have used these outlets to publicize the county’s household hazardous waste collection days and we will seek to include more messages related to storm water pollution prevention aimed at City residents. • Utah County Storm Water Coalition (UCSC) School Education Program: During 2006- 2007, the UCSC hired an instructor who has taken on the load of doing classroom presentations. As a participating member of the Coalition, we use this resource to educate students in our city. The City supports this effort by providing financial support and oversight in the form of membership on the Coalition’s Education Subcommittee. • Storm Water Hotline: This telephone number (801-229-7577) is publicized in most storm water educational materials and on City vehicles. This resource is used as an opportunity
Storm Water Management Plan -2016- 1-2 MCM 1 PUBLIC EDUCATION AND OUTREACH ON STORM WATER IMPACTS
to educate both those that report problems and those that are investigated because of reports. Further details can be found in MCM 3. • Door Hangers: When residents are reported as having engaged in behaviors that are potentially harmful to water quality, staff uses door hangers to inform residents of the issue and the solution to the issue. These can lead to actions under the IDDE program if not addressed. • City Website: Many water quality topics are covered on the website. These outlets are selected to reach a large number of people with messages that are meant to educate and inform the public about the potential for detrimental impacts of storm water discharges into public waters. Purpose and Benefit: These outlets allow for discussion of many common activities that affect the amount of target pollutants exposed to storm water throughout the City. These activities include at a minimum: • maintenance of septic systems • outdoor activities such as lawn care including use of pesticides, herbicides, and fertilizers (spring of each year) • on-site infiltration of storm water • automotive repairs • car-washing • proper disposal of swimming pool water (summer of each year) • proper management of pet waste • building and equipment maintenance • use of salt and de-icing materials (fall of each year) • proper storage of materials • proper solid waste management (dumpsters) • Stockpile management, especially as it relates to landscaping activities (spring of each year) • Emphasis will be given to the hazards of illicit discharges (in April to coincide with County collection day) Measure of Success: The city tracks phone calls, emails and social media interactions received related to topics discussed in outreach efforts. In addition, with the publication of this revised SWMP, the City will maintain a log of General Public outreach efforts by date published, topic, format and public comment of response. This task will be evaluated annually according to the Storm Water Management Plan Measureable Goals Matrix to ensure that messages are focused and effective for the general public. It will also be reviewed to see how well it is helping to achieve behavioral changes that lead to better water quality. Responsible Staff: Storm Water Engineering Specialist

The City of Orem recommends developers consider Low Impact Design (LID) through the use of the UDWQ’s manual “A Guide to Low Impact Development within Utah”. Additional resources can be found at the International Storm Water BMP Database and the EPA's National Menu of Best Management Practices (BMPs) for Stormwater. The preceding web sites list expected removal rates from a variety of BMP’s and the technical basis and studies which supports these performance claims. In order to protect the receiving water bodies, design BMPs for new or redeveloped sites are required. Developers must design BMPs to treat storm water with a goal of reducing pollutants in the receiving water bodies. BMPs should address removal of phosphorous, total suspended solids, and other target pollutants. Proposed BMPs will be evaluated by City staff to verify selected BMPs are addressing pollutant removal.
Purpose and Benefit: Creating procedures and checklists allow for uniform review of sites based on agreed upon objective criteria. This consistency should lead to better compliance as contractors, developers and engineers are able to recognize patterns applicable to sites throughout the City. Measure of Success: Required use of Low Impact Design elements in all new development and redevelopment.

LTM-3: Long-Term Storm Water Management Plan Review
Year Originally Executed: 2003 Last Reviewed: June 6, 2019 Reference Regulation: 4.2.5.4-4.2.5.4.3 Target Pollutants: Nutrients; Hydrocarbons; Heavy Metals; Sediment; Toxic Chemicals; Litter/Trash, Debris; Pathogens Audiences: MS4 Employees Description: Development can alter landscapes by increasing imperviousness (i.e. roofs, driveways, parking lots) and changing drainage patterns, thereby increasing the volume and velocity of runoff from the site. Increased volume leads to degradation of receiving waters and increases in the occurrence of flooding. Storm water from developed impervious areas can also contain a variety of pollutants that are detrimental to water quality, such as sediment, nutrients, road salts, heavy metals, pathogenic bacteria, and petroleum hydrocarbons. Considering water quality impacts early in the design process can provide long-term water quality benefits. New development projects on undeveloped land offer many opportunities to reduce storm water runoff from the site. Redevelopment projects, which replace an existing development and are typically in more urban areas, usually have less land area available for storm water controls. The City of Orem as a Phase II regulated municipality has developed ordinances, which require property owners and operators to include a combination of structural and non-structural BMPs and ensure adequate long-term operation and maintenance of BMPs. To do this, the City needs to thoroughly review development plans and supporting documents to ensure that they minimize water quality impacts from the site after construction is complete. Depending on the development type and location, different BMP’s may apply. The City of Orem recommends developers consider Low Impact Design (LID) and BMP selection through the use of the UDWQ’s manual “A Guide to Low Impact Development within Utah”. Additional resources can be found at the International Storm Water BMP Database and the EPA's National Menu of Best Management Practices (BMPs) for Stormwater. The City will keep a record on hand of those materials that are provided to design professionals. If mass mailings are distributed to design professionals, the date and list of recipients will be recorded. Purpose and Benefit: Plan review allows for the evaluation of selected BMPs and guidance for developers from planning to construction to long-term maintenance. Measure of Success: Review site plan and subdivision reviews, deficiencies discovered by these reviews and the actions taken to remedy these deficiencies according to the Storm Water Management Plan Measureable Goals Matrix. These plans are found in the DRC folder on the Orem3 server.

The standards used have been selected by the Development Services Department under the direction of the City Engineer. The Storm Water Utility is providing guidance in the process ensuring that UPDES standards of management/retention are met. The review of plan designs will require the technical rationale should this standard be unachievable for a given site. Exemptions can be obtained if retention is not feasible due to site constraints, poor percolation, high groundwater levels, etc. The City Engineer will use engineering judgement to determine if the exemption request will be accepted or denied on a case-by-case basis. If an exemption is accepted, developers will be required to provide a plan identifying the means by which water quality will be protected to the City Engineer for his approval. Purpose and Benefit: Reducing runoff from sites and encouraging the infiltration, evapotranspiration and/or reuse of storm water allows for groundwater recharge and minimizes potentially adverse impacts to downstream waters.

This process involves the technical development review with engineering, public works and public safety. It promotes non-structural BMPs such as minimizing disturbance areas, preserving areas deemed important for water quality benefits, implementing flood control and protecting natural resources. It also requires the evaluation of LID and green infrastructure to implement infiltration, evapotranspiration and storm water harvesting in accordance with state regulations. If LID is determined not to be feasible, documentation explaining site limitations must be submitted to City personnel for review and approved prior to construction. BMPs will be reviewed to ensure that they will address anticipated pollutants from the developed site. Additionally this process of preconstruction and review meetings is a time to review maintenance agreements. Purpose and Benefit: The best way to integrate long-term storm water quality measures into a site is during planning and review.

Amend Orem City Code as follows: Orem City Ordinance 23-4-8(13). Retrofitting Plan The City shall develop a plan to retrofit those properties described in Section 23-4-8(2) that are adversely impacting water quality. The plan shall emphasize controls that infiltrate, evapotranspire or harvest and use storm water discharges and shall rank those controls measures that are best suited and those controls that may considered for future retrofitting. The retrofitting plan will include the following criteria: 1. Proximity to waterbody; 2. Status of waterbody to improve impaired waterbodies and protect unimpaired waterbodies; 3. Hydrologic condition of the receiving waterbody; 4. Proximity to sensitive ecosystem or protected area; and 5. Any site included in Section 23-4-8-(2) that could be further enhanced by retrofitting storm water controls.
II. Implementation of Ordinance Amendment OCC § 23-4-8(13):
• Step One: The City shall identify existing developed properties described in Orem City Code Section 23-4-8(2) that may be adversely impacting water quality. The City shall prioritize and perform risk assessments on those properties that are located near significant waterbodies such as Utah Lake or the Provo River, sensitive ecosystems or protected areas focusing first on public property which the City owns or properties where a violation is reported and then expanding when able to assessments of private property similarly located. • Step Two: In performing the risk assessments, the City shall consider the following: 1. Proximity to waterbody; 2. Status of waterbody to improve impaired waterbodies and protect unimpaired waterbodies; 3. Hydrologic condition of the receiving waterbody; 4. Proximity to sensitive ecosystem or protected area; and 5. Any site included in Section 23-4-8-(2) that could be further enhanced by retrofitting storm water controls. • Step Three: The City shall continue to use the risk assessment list that is part of its Storm Water Quality Credit Package program and will include as part of the assessment the five criteria included in Orem City Code § 23-4-8(13). The City will, when financial feasible, continue to encourage private property owners to implement control measures through education and private property inspection. • Step Four: the City shall continue to require redevelopment projects to complete a LTSWMP and to add LID controls to the project even when a permit is not required. In so doing, the City will consider the five criteria found in Orem City Code § 23-4-8(13) when reviewing the LTSWMP.
III. Prioritization of Current and Future Control Measure retrofits. The City recognizes that some existing areas may pose a risk of storm water contamination and an ongoing retrofit program may reduce potential contamination risks. In an effort to reduce storm water contamination risks, the City is currently taking measures to upgrade city owned infrastructure and require or encourage upgrades to privately owned infrastructure. The improvement plan listed below has been expanded to include the entire city due to Wellhead Protection Zones and is not limited by the criteria listed in Step Two above:
• City owned drainage infrastructure to meet existing pretreatment standards on Capital Improvement Projects (CIPs). All upcoming storm drain projects have been prioritized and can be found in the 2018 Storm Water Master Plan at the following link: https://orem.org/wp- content/uploads/2017/09/Orem_Storm_Water_Master_Plan_opt_reduced-3.pdf • City projects that are non-Storm Water Master Plan projects such as street improvements, comprehensive water line upgrades, comprehensive sewer line upgrades, and traffic light projects are all held to the same standards as storm water projects and required to upgrade storm drain infrastructure to existing Orem City pretreatment standards. • Encourage use of the City of Orem Storm Water Quality Credit Program. This program encourages business to utilize a combination of structural and non-structural BMPs to reduce storm water contamination risk through storm water assessment reduction. The requirements for this program can be found at https://orem.org/storm-water-credit/ • Private redevelopment projects are required to upgrade storm water infrastructure to Orem City pretreatment standards, route roof drainage to landscape areas where possible, and utilize the Subdivision/Site Plan Review Checklist that can be accessed at https://orem.org/wp-content/uploads/2019/06/DRC_Subdivision_checklist.pdf to meet other LID requirements. The City has ranked control measures, with the highest probability of success to prevent storm water pollution, as listed below in this prioritized list.
• Retrofit pretreatment manholes on existing sumps and other storm water infrastructure for ongoing City CIP projects to current pretreatment standards. • Require private redevelopment projects to upgrade all existing storm water infrastructure to current Orem City pretreatment standards. • Require current Orem City storm water retention standards for each public and private redevelopment project as required in current Orem City Municipal Code. (23-4-8(7)) • Require roof drainage on public and private redevelopment projects to be directed to landscaping and infiltrated where technically feasible. • Encourage curb cuts to utilize pervious areas for retention and infiltration of storm water and to help meet LID requirements. • Encourage vegetative areas in detention/retention areas to aid in infiltration and evapotranspiration of storm water and to help meet LID requirements. Controls that may considered for future retrofitting.
• All control measures listed above will continue to be considered or required. • Green roofs. • Bioswales. • Expanded use of vegetative swales.
