Update on Water Efficient Landscape Ordinance P1 1 MEMORANDUM TO: Mayor and City Council FROM: Lee Ledesma, Utilities Finance & Administrative Manager THRU: David Hornbacher, Director of Utilities Scott Miller, Public Works Director DATE OF MEMO: June 8, 2018 MEETING DATE: June 12, 2018 RE: Water Efficient Landscape Ordinance Worksession -- Proposed Changes to Water Efficient Landscaping Standards REQUEST OF COUNCIL: Staff requests review of, and feedback on, proposed changes to the Water Efficient Landscaping Standards, which includes extending the pilot program; incentivizing stormwater best management practices, native landscapes and rain barrels; and, updating design criteria and exemptions. As stated in Ordinance No. 16, Series 17, Water Efficient Landscape Ordinance, Sec. 25.30.020, the City of Aspen Water Efficient Landscaping Standards may be amended from time to time by City Council Resolution. At least one (1) copy of the City of Aspen Water Efficient Landscaping Standards shall be available for inspection at the City of Aspen Utilities Department, the City of Aspen Parks Department, and City of Aspen Community Development Department. It is Staff’s proposal to place updated Water Efficient Landscaping Standards on a Regular City Council consent agenda in the coming month for Council’s review and approval. PREVIOUS COUNCIL ACTION: On February 13, 2018, Staff presented an update on the Water Efficient Landscape Ordinance. This update included: · Overview of Water Efficient Landscaping Standards · Status of Pilot Implementation · Third Party Audits · Next Steps The February 2018 Worksession was a follow up to the adoption of the Water Efficient Landscape Ordinance on May 22, 2017, which went in effect on June 22, 2017 and applied to all city and county parcels that are on City of Aspen water. P2 I. 2 The Water Efficient Landscape Ordinance is a lead action step contained in both the Regional and Municipal Water Efficiency Plans that were adopted by City Council on September 28, 2015. BACKGROUND: Conservation is a key component of Aspen’s Integrated Water Supply System and effective conservation practices enable the City to manage our water supplies more efficiently. The City of Aspen has been promoting water efficiency since the mid-1990s. The City approved its first water conservation plan in 1996. Additionally, the City currently has water efficiency assessments on five (5) of its parks and will use recommendations from these reports to increase water efficiency. Assessments will be completed on fifteen (15) more parks in 2018, as the City continues to pursue impactful water savings. DISCUSSION: The four main agenda items for this Water Efficient Landscape Ordinance are: · Plans Review Update · Landscaping Standards Recommended Changes · Pilot Program Update & Recommendations · QWEL Certification Plans Review Update: Will include overview of properties in pilot program, including compliance rate and average property landscape distribution. Landscape Standards Recommended Changes: Will include a description of the proposed programmatical level changes, such as water budget incentives, exemptions, specific design criteria and possible future topics. Pilot Program Update & Recommendations: Will discuss Pilot Phase approach as it relates to the information gathering period and the current requirements of the program. QWEL Certification: Will include an update on the Qualified Water Efficient Landscape professional certification program being implemented locally to support the landscape irrigation system third party audit process. FINANCIAL IMPACTS: Current staff time to manage the Water Efficient Landscape Ordinance includes approximately ¾ FTE in the Parks department and a ½ FTE in the Water department. For 2019 budget preparation, City Utilities will be requesting one full-time employee (FTE) for Parks department plans review and ½ FTE for Water department permit coordinator. Both requests will be part of the 2019 Budget presentation in October. Currently, the above-mentioned expenses are covered by an existing Utilities Development Review fee, which has not increased since January 2017 for city and county water customers. ENVIRONMENTAL IMPACTS: If a maximum water budget of 7.5 gallons/sq.ft./season is utilized after the end of the pilot phase, the Landscape Ordinance is estimated to reduce irrigation water demand by 14 % as compared to new plan submittals sampled prior to implementation. And, when compared to typical existing homes, there is a potential landscape water use savings of up to 60% when these properties refresh their landscaping and irrigation systems. Using a water budget of 7.5 gallons/sq. ft./irrigation season (14% savings) would put the City on target to P3 I. 3 achieve the 2015 Water Efficiency Plan projection of 50 acre-feet per year of water savings by 2035. RECOMMENDED ACTION: Staff recommends Council provide direction on both the length of the pilot program and possible changes to the existing Water Efficient Landscaping Standards. ALTERNATIVES: City Council could choose to not address these proposed modifications now and request an additional update on the pilot program and landscaping standards at some future date.

Certified landscape irrigation auditor: a person certified to perform landscape irrigation audits by an accredited academic institution, the Irrigation Association’s Certified Landscape Irrigation Auditor program, the Qualified Water Efficient Landscaper program, a professional trade organization or other program labeled by U.S. Environmental Protection Agency’s WaterSense program. Distribution uniformity: the measure of the uniformity of irrigation water over a defined area. Disturbance area: disturbance is defined by the external area of the building where the ground is disturbed which includes but is not limited to soil grading, landscaping, removing impervious area, adding impervious area, replacing impervious area, layback areas, and stock pile areas. This includes areas disturbed within Right-of-Ways. Ecological restoration project: a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem. Emission device: a component of the system that disperses water to the landscape and includes sprinklers, bubblers, emitters, micro sprays, etc. Established landscape: the point at which plants in the landscape have developed roots into the soil adjacent to the root ball. Typically, most plants are established after one or two years of growth. Establishment irrigation: permanent irrigation intended to water plants only during the establishment period. Irrigation remains in the area for future drought protection. Establishment period: a length of time after installing plant where the plants are given one (1) to three (3) years of irrigation, dependent on the plant type. During this period, plants must slowly be weaned off of water supply to optimize tolerance of natural precipitation rates. Native habitat mitigation areas and trees may need three to five years for establishment. Note: Temporary water taps and reimbursable utility connection permit fees may be required by Aspen Water Department. Evapotranspiration: the quantity of water evaporated from adjacent soil and other surfaces and transpired by plants during a specified time. See below for “reference ET”.

Please refer to the Urban Runoff Management Plan for more information. Hardscapes: a landscape feature that is made of any durable material (pervious and non-pervious). Hydrozone: a portion of the landscaped area having plants with similar water needs that are served by a valve or set of valves with the same schedule. A hydrozone may be irrigated or non-irrigated. For example, a naturalized area planted with native vegetation that will not need supplemental irrigation once established is a non-irrigated hydrozone. Infiltration rate: the rate of water entry into the soil expressed as a depth of water per unit of time (inches per hour). Irrigation audit: an in-depth evaluation of the performance of an irrigation system conducted by a Certified Landscape Irrigation Auditor. An irrigation audit includes, but is not limited to: inspection, system tune-up, system test with distribution uniformity or emission uniformity, reporting overspray or runoff that causes overland flow, and preparation of an irrigation schedule. The audit shall be conducted in a manner consistent with the Irrigation Association’s Landscape Irrigation Auditor Certification program or other U.S. Environmental Protection Agency “WaterSense” labeled auditing program.

FOR DISCUSSION PURPOSES ONLY City of Aspen Water Efficient Landscaping Standards Page 9 of 27 Landscaping and/or landscape improvements: plantings of grass, shrubs, trees or similar living plants, with minimal use of other ground surface treatment such as decorative rock, bark, or stone. These inert materials are allowed to be used in conjunction with live material in planting beds, but do not count toward the calculations of required landscaping and/or landscaping improvements. Landscape water meter: an inline device installed at the irrigation supply point that measures the volume of water into the irrigation system by using a flow totalizing device to record water use. Lateral line: the water delivery pipeline that supplies water to the emitters or sprinklers from the valve. Low flow irrigation or drip irrigation: the application of irrigation water at low pressure through a system of tubing or lateral lines and emitters such as point source emitters, dripper lines, micro sprays and bubblers. Low flow irrigation systems apply small volumes of water slowly at or near the root zone of plants. Main line: the pressurized pipeline that delivers water from the water source to the valve or outlet. Master shut-off valve: a lockable automatic valve installed at the irrigation supply point which controls water flow into the irrigation system. When this valve is closed, water will not be supplied to the irrigation system. Maximum Applied Water Budget: the upper limit of annual applied water (supplemental irrigation water) for the established landscaped area as specified in Appendix A. It is based upon the area’s reference evapotranspiration and is adjusted for plant factors and irrigation efficiency, two major influences upon the amount of water that needs to be applied to the landscape. Microclimate: the climate of a small, specific area that may contrast with the climate of the overall landscape area due to factors such as wind, sun exposure, plant density, or proximity to reflective surfaces. Mulch: any organic material such as leaves, bark, straw, compost or inorganic mineral materials such as rocks, gravel, pebbles, or decomposed granite left loose and applied to the soil surface for the beneficial purposes of reducing evaporation, suppressing weeds, moderating soil temperature, and preventing soil erosion. New construction: for the purposes of these standards, a new building with a landscape or other new landscape, such as a park, playground, or greenbelt. Non-residential landscape: landscapes in commercial, institutional, industrial and public settings that may have areas designated for recreation or public assembly. It also includes portions of common areas of common interest developments with designated recreational areas. Operating pressure: the pressure at which the parts of an irrigation system are designed by the manufacturer to operate. Overhead sprinkler irrigation systems: systems that deliver water through the air (pop-ups, rotors, etc.) Overspray: the water that is delivered beyond the target area. P14 I.

A project applicant may be the property owner or designee including the contractor. Rain barrel: a storage container with a sealable lid that is: (a) located aboveground outside of a residential home; (b) used for collecting precipitation from a downspout of a rooftop; and (c) in compliance with current Colorado statutes, as administered by the Colorado Division of Water Resources.1 Rain sensor or rain sensing shut-off device: a component which automatically suspends an irrigation event when it rains. Reclaimed water, recycled water, or treated sewage effluent water: treated or recycled waste water of a quality suitable for non-potable uses such as landscape irrigation and water features. This water is not intended for human consumption. Record drawing: a set of reproducible drawings which show changes in the work made during construction and which are usually based on drawings marked up in the field and other data furnished by the contractor. Recreational area: areas of active play or recreation such as sports fields, school yards, picnic grounds, or other areas with intense foot traffic. Reference evapotranspiration or ET: a standard measurement of environmental parameters which affect the water use of plants. ET is typically expressed as the depth of water in inches or the volume of water in gallons used by an irrigated landscape area over a period of time, as represented in Appendix A, and is based on an estimate of the evapotranspiration of a large field of four- to seven-inch tall, cool- season grass that is well watered. Reference evapotranspiration (ETo) is used as the basis of determining the Maximum Applied Water Budget. One inch is approximately 0.623 gallons per square foot. Remote control valve: a device used to control the flow of water in the irrigation system. Residential landscape: landscapes surrounding single or multifamily homes such as duplexes. Runoff: water which is not absorbed by the soil or landscape to which it is applied and flows from the area. For example, runoff may result from water that is applied at too great a rate (application rate exceeds infiltration rate), run times are set too long or a valve is stuck open, when there is a severe slope, etc. Smart irrigation controller: an automatic timing device with nonvolatile memory used to remotely control valves that operate an irrigation system. Smart irrigation controllers are able to self-adjust and 1 See additional information regarding HB 16-1005: http://water.state.co.us/SurfaceWater/RainwaterCollection/Pages/default.aspx) P15 I.

Fact Sheet No. 6.303 Natural Resources Series|Forestry by F.C. Dennis* Colorado’s population is growing, its urban areas are rapidly expanding, and people are building more homes in what was once natural forest and brushlands. Newcomers to rural areas need to know how to correctly landscape their property to reduce wildfire hazards. Improper landscaping worries land managers and fire officials because it can greatly increase the risk of structure and property damage from wildfire. It is a question of when, not if, a wildfire will strike any particular area. Vegetative clearance around the house (defensible space) is a primary determinant of a home’s ability to survive wildfire. Defensible space is, simply, room for firefighters to do their job. If grasses, brush, trees and other common forest fuels are removed, reduced, or modified to lessen a fire’s intensity and keep it away from the home, chances increase that the structure will survive. It is a little- known fact that in the absence of a defensible space, firefighters will often bypass a house, choosing to make their stand at a home where their safety is more assured and the chance to successfully protect the structure is greater. Landscaping Defensible Space People often resist creating defensible space because they believe that it will be unattractive, unnatural and sterile-looking. It doesn’t have to be! Wise landowners carefully plan landscaping within the defensible space. This effort yields a many-fold return of beauty, enjoyment and added property value. Development of defensible space is outlined in fact sheet 6.302, Creating Wildfire- Defensible Zones. Colorado has great diversity in climate, geology and vegetation. Home and cabin sites can be found from the foothills through Quick Facts • More people are moving into Colorado’s rural areas, increasing the chances of wildfire. • “Defensible space” is the primary determinant of a structure’s ability to survive wildfire. • Native species are generally the best plant materials for landscaping in defensible space, but others can be grown successfully in Colorado. • To be a FireWise homeowner, plan well, plant well and maintain well. *Staff Forester (retired), Colorado State Forest Service. 1/2012 Fire-Resistant Landscaping 10,000-foot elevations. Such extremes present a challenge in recommending plants. While native plant materials generally are best, a wide range of species can be grown successfully in Colorado. Many plant species are suitable for landscaping in defensible space. Use restraint and common sense, and pay attention to plant arrangement and maintenance. It has often been said that how and where you plant are more important than what you plant. While this is indeed true, given a choice among plants, choose those that are more resistant to wildfire. Consider the following factors when planning, designing and planting the FireWise landscape within your home’s defensible space: • Landscape according to the recommended defensible-space zones. That is, the plants near your home should be more widely spaced and lower growing than those farther away. • Do not plant in large masses. Instead, plant in small, irregular clusters or islands. • Use decorative rock, gravel and stepping stone pathways to break up the continuity of the vegetation and fuels. This can modify fire behavior and slow the spread of fire across your property. • Incorporate a diversity of plant types and species in your landscape. Not only will this be visually satisfying, but it should help keep pests and diseases from causing problems within the whole landscape. • In the event of drought and water rationing, prioritize plants to be saved. Provide available supplemental water to plants closest to your house. • Use mulches to conserve moisture and reduce weed growth. Mulch can be organic or inorganic. Do not use pine bark, thick layers of pine needles or other mulches that readily carry fire. • Be creative! Further vary your landscape by including bulbs, garden art and containers for added color. © Colorado State University Extension. 5/99. Reviewed 01/12. www.ext.colostate.edu P54 I. Grasses During much of the year, grasses ignite easily and burn rapidly. Tall grass will quickly carry fire to your house. Mow grasses low in the inner zones of the defensible space. Keep them short closest to the house and gradually increase height outward from the house, to a maximum of 8 inches. This is particularly important during fall, winter and before green-up in early spring, when grasses are dry, dormant and in a “cured” fuel condition. Given Colorado’s extremely variable weather, wildfires can occur any time of the year. Maintenance of the grassy areas around your home is critical. Mow grasses low around the garage, outbuildings, decks, firewood piles, propane tanks, shrubs, and specimen trees with low-growing branches. Ground Cover Plants Replace bare, weedy or unsightly patches near your home with ground covers, rock gardens, vegetable gardens and mulches. Ground cover plants are a good alternative to grass for parts of your defensible space. They break up the monotony of grass and enhance the beauty of your landscape. They provide a variety of textures and color and help reduce soil erosion. Consider ground cover plants for areas where access for mowing or other maintenance is difficult, on steep slopes and on hot, dry exposures. Ground cover plants are usually low growing. They are succulent or have other FireWise characteristics that make them useful, functional and attractive. When planted in beds surrounded by walkways and paths, in raised beds or as part of a rock garden, they become an effective barrier to fire spread. The ideal groundcover plant is one which will spread, forming a dense mat of roots and foliage that reduces soil erosion and excludes weeds. Mulch helps control erosion, conserve moisture and reduce weed growth. It can be organic (compost, leaf mold, bark chips, shredded leaves) or it can be inorganic (gravel, rock, decomposing granite). When using organic mulches, use just enough to reduce weed and grass growth. Avoid thick layers. When exposed to fire, they tend to smolder and are difficult to extinguish. Likewise, while your property might yield an abundance of needles from your native pines or other conifers, don’t use them as mulch because they can readily catch and spread wildfire. Rake, gather and dispose of them often within your defensible space. Wildflowers Wildflowers bring variety to a landscape and provide color from May until frost. Wildflower beds give a softer, more natural appearance to the otherwise manicured look often resulting from defensible space development. A concern with wildflowers is the tall, dense areas of available fuel they can form, especially in dormancy. To reduce fire hazard, plant wildflowers in widely separated beds within the defensible space. Do not plant them next to structures unless the beds are frequently watered and weeded and vegetation is promptly removed after the first hard frost. Use gravel walkways, rock retaining walls or irrigated grass areas mowed to a low height to isolate wildflower beds from each other and from other fuels. Shrubs Shrubs lend color and variety to the landscape and provide cover and food for wildlife. However, shrubs concern fire professionals because, as the next level in the “fuel continuum,” they can add significantly to total fuel loading. Because of the woody material in their stems and branches, they are a potential source of fire brands. When carried in the smoke column ahead of the main fire, fire brands can Keep grass mown around structures to a maximum of 8 inches. Plant low-growing, nonresinous shrubs near structures. Plant wildflowers near structures only if they are well-irrigated and cut back during the dormant season. Gravel area or mow grass short next to the structure. Mow grass short around shrubs. The best tree species to plant generally are those naturally occurring on or near the site. Figure 1: Forested property surrounding a homesite shows optimum placement of vegetation near the structure. P55 I. rapidly spread the fire in a phenomenon known as “spotting.” But the primary concern with shrubs is that they are a “ladder fuel” – they can carry a relatively easy-to-control surface grass fire into tree crowns. Crown fires are difficult, sometimes impossible, to control (see Figure 2). To reduce the fire-spreading potential of shrubs, plant only widely separated, low-growing, nonresinous varieties close to structures. Do not plant them directly beneath windows or vents or where they might spread under wooden decks. Do not plant shrubs under tree crowns or use them to screen propane tanks, firewood piles or other flammable materials. Plant shrubs individually, as specimens, or in small clumps apart from each other and away from any trees within the defensible space. Mow grasses low around shrubs. Prune dead stems from shrubs annually. Remove the lower branches and suckers from species such as Gambel oak to raise the canopy away from possible surface fires. Trees Trees provide a large amount of available fuel for a fire and can be a significant source of fire brands if they do burn. Radiant heat from burning trees can ignite nearby shrubs, trees and structures. Colorado’s elevation and temperature extremes limit tree selection. The best species to plant generally are those already growing on or near the site. Others may be planted with careful selection and common sense. If your site receives enough moisture to grow them, plant deciduous trees such as aspen or narrow-leaf cottonwood. These species, even when planted in dense clumps, generally do not burn well, if at all. The greatest problem with these trees is the accumulation of dead leaves in the fall. Remove accumulations close to structures as soon as possible after leaf drop. When site or available moisture limits recommended species to evergreens, carefully plan their placement. Do not plant trees near structures. Leave plenty of room between trees to allow for their growth. Spacing within the defensible space should be at least 10 feet between the edges of tree crowns. On steep ground, allow even more space between crowns. Plant smaller trees initially on a 20- to 25-foot spacing to allow for tree growth. At some point, you will have to thin your trees to retain proper  spacing. As the trees grow, prune branches to a height of 10 feet above the ground. Do not overprune the crowns. A good rule of Figure 2: Ladder fuels enable fire to travel from the ground surface into shrubs and then into the tree canopy. Structural Elements of a FireWise Landscape When building a deck or patio, use concrete, flagstone or rock instead of wood. These materials do not burn and do not collect flammable debris like the space between planks in wooden decking. Where appropriate on steeper ground, use retaining walls to reduce the steepness of the slope. This, in turn, reduces the rate of fire spread. Retaining walls also act as physical barriers to fire spread and help deflect heat from the fire upwards and away from structures. Rock or masonry walls are best, but even wooden tie walls constructed of heavy timbers will work. Put out any fires burning on tie walls after the main fire front passes. On steep slopes, consider building steps and walkways around structures. This makes access easier for home maintenance and enjoyment. It also serves as a physical barrier to fire spread and increases firefighters’ speed and safety as they work to defend your home. thumb is to remove no more than one-third of the live crown of the tree when pruning. Prune existing trees as well as ones you planted. Some trees (for example, Colorado blue spruce) tend to keep a full crown. Other trees grown in the open may also exhibit a full growth habit. Limit the number of trees of this type within the defensible space. Prune others as described above and mow grasses around such specimen trees. Maintenance A landscape is a dynamic system that constantly grows and changes. Plants considered fire resistant and that have low fuel volumes can lose these characteristics over time. Your landscape, and the plants in it, must be maintained to retain their FireWise properties. o Always keep a watchful eye towards reducing the fuel volumes available to fire. Be aware of the growth habits of the plants within your landscape and of the changes that occur throughout the seasons. o Remove annuals and perennials after they have gone to seed or when the stems become overly dry. o Rake up leaves and other litter as it builds up through the season. o Mow or trim grasses to a low height within your defensible space. This is particularly important as grasses cure. o Remove plant parts damaged by snow, wind, frost or other agents. o Timely pruning is critical. Pruning not only reduces fuel volumes but also maintains healthier plants by producing more vigorous, succulent growth. o Landscape maintenance is a critical part of your home’s defense system. Even the best defensible space can be compromised through lack of maintenance. The old adage “An ounce of prevention is worth a pound of cure” applies here. P56 I.

Rainwater Collection Information Table: Additional Information Exempt Wells versus Non-Exempt Wells The table on pages 1 and 2 reference “exempt/small capacity wells” and “non-exempt/large capacity wells”. What is an exempt/small capacity well versus a non-exempt/large capacity well and which type do I have? ● Exempt/small capacity wells are often residential wells that serve no more than three single family dwellings. Exempt/small capacity wells typically have a five or six digit permit number and do not have a suffix (other than “-A” in the case of replacement wells). ● Non-exempt/large capacity wells often have a “-F” and/or “-R” at the end of the permit number. ● See the Guide to Well Permits, Water Rights, and Water Administration for more details on exempt/small capacity and non-exempt/large capacity wells. *HB16-1005: Concerning the use of rain barrels to collect precipitation from a residential rooftop for nonpotable outdoor uses (effective August 10, 2016) • Who can collect water under this law: Any single family residence or multi-family residence with 4 or fewer units. Each home in a row of homes joined by common side walls, such as duplexes, triplexes, or townhomes, is considered a single family residence. • Do I need a permit through DWR before I start collecting precipitation? No permit or other approval is required for capture and use of precipitation in rain barrels with a combined storage capacity of 110 gallons in accordance with HB 16-1005. • Where can I collect the water from: From the roof of a building that is used primarily as a residence. • How much water can I collect: You can fill and refill two rain barrels with a combined storage capacity up to 110 gallons throughout the year. • What can I collect the water in: Water must be collected in rain barrels (up to 110 gallon total capacity) with sealable lids • What can I use the water for: Outdoor uses, such as lawn and garden irrigation, on the property where the water was collected. Though the rainwater can legally be used for a variety of outdoor uses (car washing, livestock watering, hot tub filling, irrigation, etc.) rainwater users should evaluate the quality of the collected rainwater to ensure it is appropriate for the proposed outdoor use. The water cannot be used for drinking water or indoor household purposes. • Will standing water in the rain barrels create a mosquito problem? Rain barrels must have sealable lids to prevent insects or other pests from using the stored water. See the Colorado Department of Public Health and Safety’s website for more information. **SB09-080: Concerning limited exemptions for water collected from certain residential rooftops • Who can collect water under this law (SB 09-080): Any residence that has, or can qualify for, an exempt residential well permit through DWR. This law operates independently of HB16-1005. • If I do not have a well or well permit, how do I know if my property qualifies for a well permit: This will be determined by the Division of Water Resources when you apply for the required precipitation collection permit. • Do I need a permit through DWR before I start collecting precipitation? Yes, before you begin to collect precipitation in connection with an exempt well permit, you need to obtain a rooftop precipitation collection permit. Check out the Rainwater Collection on Properties with Residential Wells Fact Sheet and the Application for Rooftop Precipitation Collection System Permit for more information. • Where can I collect the water from: From the roof of a building that is used primarily as a residence. • How much water can I collect: There is no limit to the amount of water you can collect, so long as you are collecting the water from the roof of a building that is used primarily as your residence. • What can I collect the water in: Rain barrels or other types of water storage structures. Be sure to still follow best practices for mosquito management. • What can I use the water for: Those residential uses that are allowed on the exempt well permit, which may include both indoor and outdoor uses, depending on the well permit. • Other important information: o If the residence is served by a water system (such as a water tap from a municipal provider or a shared well) that supplies more than three single family dwellings, then precipitation collection is not allowed under this law. o Please review the above information on SB09-080 before completing and submitting an Application for a Rooftop Precipitation Collection System Permit. If your well has not been registered, you will also need to Register an Existing Well before applying. Have additional questions?
