General Information 

Purpose of the Questionnaire 

Stormwater discharges from developed land can negatively impact water quality through 

increases in stormwater volume and increased pollutant loads to the receiving waters. To 

strengthen its stormwater regulations, EPA’s Office of Water (OW) is considering 

revisions to the current National Pollutant Discharge Elimination System (NPDES) 

regulations including the establishment of standards for long term stormwater discharges 

from developed sites. 

To collect data to inform decisions regarding how the nation’s stormwater regulations 

should be strengthened and to support the technical and financial feasibility associated 

with this rulemaking, EPA is sending the following questionnaire to NPDES Permit 

Authorities. This questionnaire will provide EPA with information related to the 

administration of the NPDES program to: 

 Characterize the current scope, components, and implementation of existing state 

and regional NPDES stormwater programs; ordinances and laws that may 

constrain the utilization of stormwater retention practices; and retrofit 

requirements for discharges from existing development; and 

 Estimate the burden and expenditures to comply with and enforce existing 

requirements on stormwater discharges. 

The survey is presented in five sections covering the following topic areas: 

 Section A: General Information 

 Section B: Municipal Stormwater Program

 Section C: Construction Stormwater Program

 Section D: Standards for Stormwater Discharges from New and 

 Redevelopment and Implementation of Stormwater Retention 

 Practices

 Section E: Industrial Stormwater Program

Definitions 

Note that the following terms are defined for the purposes of this questionnaire only. 

These definitions were written as broadly as possible, relying on our regulations, 

guidance, fact sheets, etc. We acknowledge that there are likely local or regional 

differences in the meanings of some of these terms. Where those differences will affect 

their answer to the questions, respondents should provide information on those 

differences in the survey blanks provided. 

Term Definition 

Construction 

The period of time during which construction activity 

(clearing, grading, and excavation) and other earth-disturbing 

activities are occurring on a site and prior to the time that 

disturbed portions of the site are considered stabilized. 

Bioretention cells 

Landscaping features adapted to provide on-site removal of 

pollutants from stormwater discharges. Surface discharges are 

directed into shallow, landscape depressions, which are 

designed to incorporate many of the pollutant removal 

mechanisms that operate in forested or other natural (prairies, 

wetlands, etc) ecosystems. Includes rain gardens, sidewalk 

planters, curb extensions and other plant or soil systems 

designed to infiltrate or evapotranspirate stormwater. 

Capacity 

Describes the hydraulic capacity that the storm sewer system is 

designed for in terms of the volume of stormwater that it can 

convey without flooding beyond design. 

Catch Basin 

An inlet to the storm sewer system, which typically includes a 

grate or curb inlet, and a sump, to capture sediment, debris, 

and other pollutants. Also known as “storm drain inlets” or 

“curb inlets”. 

Cistern 

Large storage devices that are often built below ground, at 

ground level, or on rooftops, for storing captured stormwater 

and can be integrated with more sophisticated pumping 

devices. For example, some cisterns collect stormwater that is 

subsequently used for non-potable plumbing, such as flushing 

of toilets, or irrigation applications. 

Combined Sewer 

System (CSS) 

A publicly owned conveyance system that conveys stormwater 

discharges combined with municipal sewage (domestic, 

commercial and industrial wastewater) through a single pipe 

system to a publicly owned treatment works.

Term Definition 

Constructed Wetland 

A man-made basin that contains water, a substrate (soil, gravel, 

rock, organic materials, etc.), plants (vascular and nonvascular), and organisms similar to those usually found in 

natural wetlands. The number of plants and the biodiversity of 

a constructed wetland are greater than that of wet retention 

pond. Constructed wetlands usually use a relatively 

impermeable subsurface layer to prevent water from seeping 

into the ground. 

Co-Permittee 

A permitting arrangement under which two or more MS4s are 

covered under the same NPDES permit. Responsibilities 

under the permit may be divided among the different MS4 copermittees in accordance with jurisdictional boundaries. 

Curb and Gutter 

An engineering approach to convey stormwater through the 

use of a raised, concrete or stone border along a roadside 

(curb) and a channel (gutter) that directs stormwater discharges 

to a storm sewer system. 

Detention/ Extended 

Detention Practices 

Practices which hold stormwater temporarily and discharge the 

stormwater over an expended period of time (hours to days) 

generally by controlling the size of the discharge volume and 

flow rate. Also known as “wet/dry ponds”, “extended detention 

basins”, “detention ponds”, “extended detention ponds.” 

Existing Development 

Describes an existing lot/parcel with an impervious surfaces 

from prior development, or is significantly degraded and is 

covered with sand, gravel, stones, or other non-vegetative 

covering, or is considered a “brownfield site”. 

Vegetated Buffer 

Vegetated surfaces used to reduce stormwater velocity from 

nearby less pervious surfaces, and to filter out pollutants from 

stormwater and allow infiltration into the underlying soil. Also 

referred to as “riparian buffer” if established around streams, 

lakes, and/or wetlands. 

Flood event 

Describes an overflow of stormwater from a storm sewer 

system during peak flow conditions as a result of a storm 

event. 

Full Time Equivalent 

(FTE) 

The number of full-time employees that could have been 

employed if the reported number of hours worked by part-time 

employees had been worked by full-time employees. This 

statistic is calculated separately for each function of a 

government by dividing the “part- time hours paid” by the 

standard number of hours for full-time employees in the 

particular government and then adding the resulting quotient to 

the number of full-time employees.

Term Definition 

Green Roof 

A vegetative system installed on top of and in addition to the 

traditional roof system. A green roof includes engineered soil 

layers (e.g., a waterproof membrane, drainage, high inorganic 

growing media), and appropriate plant species. Green roofs 

reduce surface discharges from the rooftop by absorbing 

stormwater and slowing stormwater flow rates, and provide 

ancillary benefits such as summer cooling, lowered urban heat 

island effect, and improved air quality. 

Green Infrastructure 

Wet weather management approaches and technologies that 

infiltrate, evapotranspire, capture and reuse stormwater to 

maintain or restore natural hydrology. 

Impervious Area 

The total area of a parcel or right-of-way that consists of 

buildings and associated constructed facilities; areas that are 

covered with a low-permeability material such as asphalt or 

concrete; or areas such as gravel roads and unpaved parking 

areas that are compacted through design or use to reduce their 

permeability. Common impervious areas include, but are not 

limited to, roads, rooftops, walkways, patios, driveways, 

parking lots or storage areas, concrete or asphalt paving, 

packed earthen materials, and macadam or other surfaces 

which similarly impede the natural infiltration of storm water. 

Industrial Facility 

A facility engaged in any of the industrial activities 

specifically listed in 40 CFR 122.26(b)(14) or has been 

designated as causing a water quality standard exceedance or 

as a significant contributor of pollutants to waters of the U.S. 

under 40 CFR 122.26(a)(1)(v). 

Infill Development 

Describes development activity that occurs on a generally 

undeveloped lot/parcel that is situated in an area in which most 

lots/parcels have already been developed. 

Long Term (Post 

Construction) 

Stormwater Controls 

See Post Construction 

Low Impact 

Development (LID) 

Development that is designed to be hydrologically functional 

by mimicking pre-development hydrology conditions. This is 

achieved by using design techniques that infiltrate, filter, 

evaporate, and store discharges close to its source.

Pavement composed of a permeable pavement material, which 

allows distributed infiltration into the underlying soil. There 

may also be an underlying stone reservoir that temporarily 

stores the surface discharges before it infiltrates into the 

underlying soil. Examples include pervious concrete, porous 

asphalt, permeable pavers. 

Post Construction 

Describes the phase of development immediately following the 

termination of construction activities on a site. “Postconstruction discharges” are discharges of stormwater from 

developed sites. Post-construction controls are those 

stormwater controls that are installed and maintained to 

permanently manage stormwater discharged from the 

developed sites.

existing storm sewers) to enhance the reduction of stormwater 

pollutants, or discharge volume or flow rates. 

Riparian Buffer 

An area surrounding a shoreline, wetland, or stream within 

which development is restricted or prohibited. The primary 

function of aquatic buffers is to physically protect and separate 

a stream, lake, or wetland from future disturbance or

Term Definition 

Storm Sewer System 

A conveyance or system of conveyances, including roads with 

drainage systems, municipal streets, catch basins, curbs, 

gutters, ditches, manmade channels, or storm drains designed 

or used for collecting or conveying stormwater. 

Stormwater Runoff, snow melt runoff, and surface runoff and drainage. 

Stormwater Control Practices that are installed and maintained to control 

stormwater discharges. 

Stormwater Quality 

Control 

Stormwater control used to reduce or eliminate pollutants 

carried in stormwater discharges. 

Stormwater Quantity 

Control 

Stormwater control used to control or convey the volume of 

water being discharged during storm conditions. 

Swales: Grassed 

A broad, shallow channel used for conveying and management 

stormwater discharges. Grass on the side slopes and bottom 

acts to slow discharge velocity, trap particulates, and promote 

infiltration. Grassed swales are often referred to as bio-swales, 

enhanced swales, or water quality swales and can be classified 

as wet swales, dry swales, and grassed channels. See Swales: 

Other Vegetation. 

Swales: Other 

vegetation 

A broad, shallow channel used for conveying stormwater 

discharges. Vegetation on the side slopes and bottom acts to 

slow discharge velocity, trap particulates, and promote 

infiltration. Vegetated swales are often referred to as bioswales, enhanced swales, or water quality swales and can be 

classified as wet swales, dry swales, and grassed channels. 

A dry swale (bio-swale) incorporates additional elements with 

the vegetated swale design. Infiltration is aided by a soil bed 

(not necessarily natural soil) with an underdrain system 

composed of a perforated pipe surrounded by gravel. Check 

dams may be used to temporarily retain stormwater discharge. 

A wet swale is capable of temporarily retaining stormwater 

discharges, but, unlike the dry swale, lacks an underdrain 

system. The wet swale is marshlike and relies on and supports 

wetland vegetation 

Undeveloped Describes land that has not been subject to prior development. 

See “new development.” 

Urbanized Area 

A land area comprising one or more places — central place(s) 

— and the adjacent densely settled surrounding area — urban 

fringe — that together have a residential population of at least 

50,000 and an overall population density of at least 1,000 

people per square mile. Any MS4 located within a 2000 

Census-defined “urbanized area” is required to obtain an 

NPDES permit for discharges from its storm sewer system.

IMPLEMENTATION OF STORMWATER RETENTION PRACTICES 

In this section EPA is obtaining information about drivers, incentives and obstacles to the 

implementation of stormwater retention practices in the state. Stormwater retention 

practices are those that do not discharge stormwater off-site or to surface water below a 

certain design capacity (design volume, stormwater size, etc.). The stormwater is 

infiltrated, evapotranspired, or harvested. Examples are bioretention cells (includes rain 

gardens, sidewalk planters, curb extensions and other plant or soil systems designed to 

infiltrate or evapotranspirate stormwater), porous pavement, green roofs, vegetated 

swales, cisterns and other practices. These practices are commonly referred to as Low 

Impact Development (LID) or Green Infrastructure (GI) practices. 

D-18 Indicate the driver for implementation of stormwater retention practices in your 

 state. Check all that apply. 

□ Meet post construction performance standards or other requirements in the 

 state’s stormwater program 

□ Local watershed plan or considerations involving storm drainage issues 

□ NPDES WQ protection objectives (i.e. TMDL, impaired water, etc.) 

□ CSO Long Term Control Plan requirement 

□ Flood control
