Pollution Prevention and Good Housekeeping (PP/GH) Program

The Pollution Prevention and Good Housekeeping (PP/GH) minimum control measure focuses activities on ensuring that municipal facilities and operations are managed in ways that will minimize contamination to stormwater discharges from these facilities. Facilities may include, but are not limited to, municipally owned or operated buildings, campuses, parks, public works facilities, and infrastructure. Various operation and maintenance activities addressed may include but are not limited to street and bridge maintenance; road salt storage and application; vehicle and fleet maintenance; stormwater system maintenance; solid waste management; park and open space maintenance; and pesticide and fertilizer applications.

Ensure documentation is maintained for all activities described below.

Municipal Facility and Structural Stormwater Control Inventory

An inventory of all permittee-owned or operated facilities/properties with a discharge of stormwater to surface waters of the state is included in the table below.

Table 1: Permittee owned facilities and addresses.

Facility	Address
Lincoln Township Hall and Lincoln Township Hall Park	1882 N. Hope Road Midland, Michigan

An inventory identifying all stormwater structural controls with a discharge of stormwater to surface waters is included below. Additionally, an estimated number of structural stormwater controls is provided below:

Catch Basins – one
Oil/Water Separator – one

Up-To-Date Map(s)

Up to date map(s) including facilities and stormwater structural controls are available upon request at Lincoln Township Hall (1882 N. Hope Road Midland, Michigan).

Revision of Municipal Facility and Structural Stormwater Control Inventory

The municipal facility and structural stormwater control inventory and map(s) will be updated within 30 days following the addition or removal of a facility or structural stormwater control.

Facility-Specific Stormwater Management – Facility Assessment

The following criteria are used when assessing each facility identified above for the high, medium, or low potential to discharge pollutants to surface waters of the state:

1.Amount of urban pollutants and/or significant materials stored at the site (e.g., sediment, nutrients, metals, hydrocarbons, pesticides, fertilizers, herbicides, chlorides, trash, bacteria, bulk salt, brine or other site -specific pollutants.)
2.Identification of improperly stored materials.
3.The potential for polluting activities to be conducted outside (e.g., vehicle washing).
4.Proximity to water bodies.
5.Poor housekeeping practices.
6.Discharge of pollutants of concern to impaired waters.

This procedure will be updated/revised 30 days prior to discharging stormwater from a new facility and within 30 days of determining a need to update/revise the facility assessment.

Facility Specific- Stormwater Management – Prioritized Facilities

A list of prioritized facilities using the assessment provided above is included in the table below.

Table 2: Facilities Ratings on how likely to Pollute to Surface Waters of the State.

Facility	Potential to Discharge Pollutants to Surface Waters of the State	Criteria Present
Lincoln Township Hall and Lincoln Township Hall Park	Low	N/A

Facility Specific- Stormwater Management – High Potential for Pollutant Runoff

No facilities were identified with a high potential to discharge pollutants to waters of the state.

Facility Specific- Stormwater Management – Medium and Low Potential for Pollutant Runoff

The following Best Management Practices (BMPs) are implemented at facilities identified with a medium or low potential to discharge pollutants to surface waters of the state:

Good housekeeping practices such as ensuring dumpsters are in good condition and lids are closed, managing trash throughout the property etc.
Maintaining a clean and orderly facility.
Catch basin inspections/cleaning.
Parking lot sweeping.
Vegetation management.
Employee training.

Catch Basin Inspection, Maintenance, and Cleaning

All permittee owned and operated catch basins within the jurisdiction will be inspected annually.

Catch basin inspections will include observations of sediment accumulation, structural conditions, and other relevant observations (i.e., illicit discharges). Debris levels within the sump of a catch basin are determined by measuring the distance between the lowest outlet pipe and the top of the sediment with a grade rod (pole) with distance markings. The distance between the lowest outlet pipe and the bottom of the sump is also determined either by field measurement or historical record. Inspection documentation is maintained.

All applicant owned- or operated catch basins will be cleaned out when the sump is 40% or more full of sediment. The cleanout of the catch basin will be contracted out by the Township.

Other Stormwater Structural Controls Inspection and Maintenance

In addition to a catch basin, another stormwater structural control is inspected and maintained. The type of structural control and frequency of inspection and maintenance is included in the table below.

Table 3: Other Stormwater Structural Controls

Structural Control	Activity	Frequency
Mechanical Treatment	Inspection Sediment Removal	Annually As needed

Waste generated from the maintenance of the structural control will be managed in the following ways:

Clean/uncontaminated sediment may be applied to an upland area onsite and will be seeded.
Contaminated sediment will be landfilled.
Trash and debris will be landfilled.
Organic material may be composted or used as mulch onsite.

The above table and waste disposal procedures will be updated within 30 days following the implementation of a new type of structural stormwater control.

New Applicant Owned/Operated Facilities and Stormwater Structural Controls

All new permittee owned or operated facilities and stormwater structural controls for water quantity will be designed and implemented in accordance with the post-construction runoff control performance standards and long term- operation and maintenance requirements.

Maintenance Operations and Municipal Activities

The maintenance operation and municipal activities conducted by the applicant are outlined below. BMPs implemented to prevent or reduce pollutant runoff are also provided.

Table 4: Maintenance and Operations will BMPs implemented.

Activity	BMPs Implemented to Prevent and/or Reduce Pollutant Runoff
Parking Lot, Sidewalk, or Bridge Maintenance	Parking lot inspections and as needed sweeping and repairs. See Parking Lot Sweeping section below.
Unpaved Road Maintenance	N/A (Township does not own/operate/maintain any paved or unpaved roads)
Right-of-way Maintenance	N/A
Vehicle Washing/Equipment Maintenance	Vehicles will be serviced/maintained offsite, and vehicles are washed at a commercial car wash.
Cold Weather Operations: Plowing	Plowing will be contracted out.
Cold Weather Operations: Salting	Salting will be contracted out. There will be small bags of salt stored inside the Township building.

Parking Lot Sweeping

All parking lots will be inspected annually to determine if sweeping is needed. Sweeping activities are contracted out. Sweeping equipment will be operated and maintained according to the manufacturer’s operating instructions. Waste generated from sweeping activities will be managed accordingly and disposal documentation will be maintained.

Managing Vegetated Properties

Application of herbicides/pesticides is minimized to the extent practicable. If application is determined to be needed, it will be conducted by a State of Michigan certified applicator or ready-to-use products in the original containers will be used. The Township may also choose to contract out herbicide/pesticide treatment and provide necessary oversight.

Contractor Requirements and Oversight

All contractors that perform municipal operation and maintenance activities for Lincoln Township are required to comply with all pollution prevention and good housekeeping BMPs. This is accomplished through signed contractor agreements or BMPs will be included directly in the contract.

Employee Training Program

Training will occur for all staff involved in implementing or overseeing the PP/GH program. Employees will be trained to prevent and reduce stormwater pollutants from activities like maintaining Municipal Separate Storm Sewer System (MS4) infrastructure and performing daily municipal activities. Training activities will be recorded using a sign-in sheet noting the date, topics covered and the individuals who attended. Training will occur once every permit term (permit term is 5 years) for existing employees and within the first year of hire for new employees.
