Stormwater Utility Fee / Municipal Separate Storm Sewer (MS4)
Stormwater Utility Fee Implementation
North Middleton Township has begun mailing bills associated with the Township's stormwater utility fee.  For residential properties / units and agricultural properties, the stormwater fee is a flat rate of $24.00 per quarter to be billed twice a year (for a total of $96.00 per year).  For non-residential properties, the stormwater fee is based on the amount of impervious surface of the property.  Impervious surfaces include paving, roof areas, compacted gravel surfaces, and other similar surfaces.

Non-residential porperties may access North Middleton Township's GIS mapping system to see individual properties and to verify the impervious cover and associated fee calculation.  The average impervious cover of a single residential property or a single equivalent residential unit (aka 1 ERU) was determined to be 3,100 square fee (sf).  Non-residential properties will be charged $24.00 per quarter per ERU of impervious surface.  A non-residential property that has 10,000 sf of impervious area, for example, will be charged for 3 ERUs and will have a quarterly bill of $72.00.

The North Mddleton Township Supervisors approved a credit program for non-residential properties to allow credits of up to 50% of the stormwater fee for basins, vegetated swales, and other stormwater structures that have been installed on a property.  Residential properties / units and agricultural properties are billed a flat fee and do not qualify for any credits.  For a complete description of the credit program, please refer tot he North Middleton Township Stormwater Credit Manual.

Porperties that are tax exempt, as recorded by Cumberland County in the parcel's land use code, will be exempted from the stormwater fee.  Undeveloped properties, which are defined a properties with impervious area totaling less than 300 sf, will also be exempted from the stormwater fee.

The NMT Supervisors have set up an appealsprocess where any property owner can dispute the calculation or determination of a property's stormwater fee or credit.  Please refer to the NMT Stormwater Credit Manual (link) for a  more complete description of the appeals process.  As detailed in Resolution 2020-10, no fee will be required for an administrative appeal.  An example of an administrative appeal is when a non-residential property owner believes that the ERU calculation for a property is incorrect and requests a revision.  Any property owner who is not satisfied with the result of the administrative appeal process may appeal to the North Middleton Township Supervisors.  The application fee for an appeal to the Board of Supervisors is $500.00.

The stormwater service fee was established by Ordinance 2020-01, as part of the creation of a Stormwater Utility for the Township.  The township is required to meet NPDES permit obligations imposed by the state upon North Middleton  Township's stormwater conveyance and collection system (aka MS4 system).  The Stormwater Utility will u tilize funds collected by the stormwater service fee to finance capital projects to enhance the Township's stormwater system and waterways, monitor water quality discharging to the Township's streams, and meet additional state and federal MS4 requirements.
Guidelines for Maintaining Streams in Your Community
MS4  -  What Is It?
How does it Affect You as a Resident or a Business Owner:
MS4 is the Municipal Separate Storm Water Sewer System.  The MS4's are publicly owned, and maintained systems to collect and move storm water that eventually discharges into creeks, streams and rivers.  These storm sewers are separate from the more familiar waste water sewer systems.  Stormwater can be any surface water flow or runoff such as natural precipitation, drainage from watering grass and washing cars as well as roads and farm fields.  Development of our community, such as shopping centers and hoursing developments, increases impervious coverage which then increases the rate storm water runs off.  The quicker the storm water runs into our streams, the more prone property is to flooding.

The purpose of the MS4 program is to reduce the amount of pollutants to the "maximium extent practicable" (MEP) from the waterways as well as to protect the water quality of those streams and rivers.  Those pollutants include nitrogen, phosphorus and sediment.  By addressing storm water streams such as the Conodoguint and LeTort, the health of those waterways is preserved and in some areas greatly improved.

North Middleton Township will need to comply with the water quality requirements set forth in the Federal Clean Water Act.  Several Cumberland County communities have already been mandated to comply.  Those communities are more developed and populated than North Middleton.  With the 2010 census, the Township reached the threshold for population density.  This translates to the Pennsylvania Department of Environmental Protection (DEP), who enforces the Clean Water Act, will notify the Township in the near future that the township will need to meet the requirements of the Act.

The Township has already begun the process by working with our neighboring municipalities and educating staff on the regulations.  Staff is identifying and mapping stormwater inlets, outfalls and pipes within the populated areas.  The Township complex is already in compliance by storing the road salt in the salt dome.  This reduces water dissolving the salt which would flow into the Conodoguinet and affect the aquatic life.  Another example of compliancy is the fuel pumps are covered.  The cover assists in reducing any leaking from running off quickly in the event a leakage would occur.

You will be hearing more about MS4 in the future.  In the meantime, there are ways a homeowner or a business owner can help.  You can build water gardens or plant trees on your property.  Reduce the fertilizer you use on your grass and outdoor plants.  When watering outdoor plants water slowly allowing the water to seep into the ground.  This not only reduces water runoff but increases root growth thus you have a stronger plant.
Keeping Our Water Clean:  Stormwater is water from rain or melting snow that does not soak into the ground.  It flows from rooftops, over paving areas, bare soil, and sloped lawns.  Stormwater collects and transports animal waste, litter, salt, pesticides, fertilizers, oil & grease, soil and other potential pollutants which end up in our streams, lakes, rivers, wetlands and other waterways.

Nutrients such as phosphorus and nitrogen can cause the overgrowth of algae resulting in oxygen depletion in waterways.  Toxic substances from motor vehicles and careless applications of pesticides and fertilizers threaten water quality and can kill fish and other aquatic life.  Bacteria from animal wastes and improper connections to storm sewer systems can make lakes and waterways unsafe for wading, swimming and fish consumption.

A sanitary sewer system and storm sewer system are not the same.  Water that goes down a sink or other inside drain flows to either a wastewater treatment plant or to a septic system for treatment.  Water that flows through stormwater systems are not treated.

It is not just rain or snow that can cause pollutants to flow into our waterways.  For example, when you was your car on the driveway, that water, dirt, and grime ends up in the system.  That's why we need to be careful with what we put into the storm sewers.

What you can do to prevent stormwater pollution.

1.  Only rain belongs in the drain!  Do not dump anything down storm drains.  Be sure to clear away leaves and debris.

2.  Wash your car over your lawn or gravel.  This allows the ground to neutralize the soap and grime from your car rather than sending it directly to our creeks and streams.  Use biodegradable or non-toxic soap that is phosphate-free.  You can also take  your car to a commercial car wash where wastewater is either recycled or treated.

3.  Keep your car well-maintained.  Fix any fluid leaks promptly and make sure to clean up any spills.  If you perform your own automotive maintenance, automotive repair shops will accept 5 gallons of used motor oil per resident per day.

4.  Disconnect your downspouts.  You can plant a rain garden to absorb stormwater runoff.  You can also use a rain barrel to help collect runoff from your roof and gutters to be used on your lawn or garden.

5.  Use lawn or garden chemicals sparingly.  Choose organic alternatives when possible or those with low nitrogen and phosphorus numbers and check the weather forecast to avoid applying them before a storm.

6.  Mow your lawn less often.  Try to keep your lawn at least 3" in height to minimize week growth, reduce the need for watering, and decrease the likelihood of pests.  Leaving clippings on the lawn can also help block weeks and retain moisture.  Sweep your sidwalks and driveway rather than hosing them down.

7.  Plant native, low maintenance plants and grasses.  They often have longer root systems, which reduce the amount of chemicals and water needed.

8.  Pick up your pet waste.  Bacterial, parasites and viruses contained in pet waste are a health risk to other animals and people, especially children.

9.  Do not over-water your lawn and garden.  Keep sprinklers on a timer to avoid pooling water.

10.  Use less ice-melt.  Do not over-apply salt.  Choose a more environmentally-friendly alternative when possbile.

11.  Choose paving materials that allow water to soak through.  Use bricks, gravel, cobbles, natural stone, or permeable pavers instead of asphalt or concrete when possible.

12.  Do not drain your pool, spa, or fountain into a storm drain.  Allow chlorine to dissipate for several days.  Test the water to ensure the residual chlorine is zero before slowly draining to a landscaped area.  You may be able to drain to a sanitary sewer.  Contact your local municipality for more information.

13.  Keep your septic system well-maintained to prevent leaks.  A leaking septic system can leach harmful bacteria into storm sewer systems and local waterways.

14.  Walk, bike, or share a ride when possible.  Driving causes air pollution which contaminates the rain and ends up in our streams and lakes.

15.  Install a rain barrel or cistern to capture roof runoff.  This helps prevent stormwater from reaching waterways and reduces the potential for pollution.  Use the captured water on your lawn or garden.  Keep the barrel emptied to not attract mosquitoes.  Check with your local municipality to install properly.
