Allen Township operates a Municipal Stormwater System (MSS) that is permitted by the Pennsylvania Department of Environmental Protection (PA DEP). This Permit currently requires that the township:
This purpose of this section of the Township's website is offered to educate residents about storm water regulations, potential water pollution or flooding as a result of our local activities in the watershed.
Nearly all of our Township newsletters have included an article about stormwater in the last five years or more as part of the PA DEP MSS Permit "public education" process, as well as information published to the Township website. Township residential and commercial development construction activities are monitored by the Township Engineer and the Northampton County Conservation District.
Storm water runoff is generated when precipitation from rain and snow melt events flow over land and impervious surfaces and does not infiltrate into the ground. The runoff from streets, lawns, farms and construction and industrial sites picks up fertilizers, dirt, chemicals, pesticides, oil, grease and many other pollutants and discharges it into our streams and rivers. This untreated discharge is detrimental to our water quality as it can adversely affect our drinking water supply and the environment. In Allen Township, polluted storm water could contaminate the Dry Run, Bertsch, Catasauqua, Hokendauqua Creek and the Lehigh River.
Many Best Management Practices (BMPs), such as detention or infiltration basins, are already in place to help keep our waters clean. The Environmental Protection Agency (EPA) website is a good place to visit for storm water information and regulations:
The Township enforces Chapter 8 of the Allen Township Code available HERE.
Allen Township regulates stormwater management through a permit that is obtained from the Pennsylvania Department of Environmental Protection (PA DEP) (www.depweb.state.pa.us) through the National Pollution and Discharge Elimination System Phase II (NPDES)/Municipals Separate Storm Sewer System (MS4). This is a federal requirement from the United States Environmental Protection Agency (USEPA) (More Info) that is administered by the PA DEP.
The Allen Township MS4 (Stormwater Discharges for Small Municipal Storm Sewer Systems) NPDES Pollution Reduction Plan draft was presented at Board of Supervisors Meeting of July 10, 2018. Written public comments concerning the draft will be accepted by the Township until August 24, 2018.
The full draft is available at the following link. Additionally, paper copies are available for review at the Township Building during normal business hours Click here to review the MS4 NPDES Permit Pollution Reduction Plan for Allen Township dated July 10, 2018.
The Township also requires a Storm Water Management Plan Review if the storm water management project is not part of a formal Land Development.
There are many ways you can help the Township with its storm water program and participate in activities and programs that will keep pollutants, chemicals, trash, and other waste products out of our waterways. Please read these tips for your lawn & garden found in the Solution to Pollution publication from the EPA.
Residents may be the first to recognize "illicit" discharges dumping into storm sewers or coming out of from storm sewer outfalls. If you see an "illicit" discharge please report it by calling the township office at 610-262-7012 between 9 a.m. and 4 p.m. weekdays, or email us at: firstname.lastname@example.org. Take photos, if possible.
Disconnect your downspout from the street drain and Plant a Rain Garden.
Rainwater from your roof is just as damaging to creeks and streams as run off from a parking lot. Let your yard help filter out impurities and infiltrate storm water back into your aquifer. If you don't have street drains, be certain storm water coming through your downspouts is directed onto your own property and not into the road, road ditch, or a neighbor's property. Consider disconnecting your downspouts and installing rain barrels instead. They can provide water for your gardens. Or, install a rain garden.
Please stop by the township building for ideas or consult the rain garden publications at the bottom of this page. The Northampton County Conservation District supports the construction of rain gardens and may provide additional information regarding the practical purposes of this type of design.
Maintain open, forested floodplains. Filling floodplains shortchanges the filtering power of natural areas and increases flooding elsewhere. It is also illegal.
Streamside trees and native vegetation help filter storm water run-off and help hold steambank soils in place. DEP recently enacted a 75' buffer alongs steams to enhance water quality and reduce storm water runoff. Use Best Management Practices to protect your steam buffer.
A naturally vegetated stream buffer will filter out excess fertilizers and pesticides from adjacent farm fields.
Follow directions for weed killers and pesticides very carefully, or consider discontinuing their use. Much of the chemicals and fertilizers you apply in the spring flow directly into the local creeks and seep into ground waters because the grass is not ready to absorb it. Set your mower height at 3 inches and use a mulching mower to create a healthy, organic lawn. Fertilize only in the fall. Consider "grasscycling".
Bring used oil to certified recycling facilities.
The typical suburban lawn is nearly as impervious as a parking lot! Native meadow grasses infiltrate storm water better and provide critical habitat for grassland birds. Consider converting a portion of your lawn into a meadow with paths through it to observe the wildlife.
Pet and animal wastes carry many harmful bacteria and possible diseases. They make creeks less amenable to native critters and require expensive water treatment for human use. Studies by the Center for Watershed Protection have found that a significant portion of fecal coliform bacteria in residential storm water originates from canine waste.
The Documents and Publications section below has been assembled by the Township to provide specific information concerning the current Act 167 Release Rate Maps, Township's MS4 permit, local study efforts such as the Bertsch and Hokendauqua Creeks Coldwater Conservation Plan as well as standard federally-funded educational materials.
