WWPIE Terms A&A (Enterprise A&A) - Enterprise A&A is a service provided by the State's Department of Administrative Services, Information Technology Enterprise (DAS-ITE). It is meant to replace all of the various user name/password combinations used by different web applications, and provide a "one-stop shop" for managing your identity information with the State. The A&A service provides a central web page for logging on to any application, so users can be sure they are connecting to the State and can use the same username and password. Comment End Date – The public comment period on a draft NPDES permit ends on the comments end date. This is the last day that comments can be submitted on a draft permit. Draft Permit - an NPDES permit in the draft stage. Draft permits have not been issued as final. Expiration Date - the date a final NPDES permit expires. If a complete permit application has been submitted at least 180 days before the expiration date of the current permit, the permit will be administratively extended until a new permit is issued. Final Permit - an NPDES permit that has been issued. Issue Date - the date a final NPDES permit is issued. NPDES Permit (National Pollutant Discharge Elimination System Permit) - means an operation permit, issued after the department has obtained approval of its National Pollutant Discharge Elimination System program from the EPA administrator, that authorizes the discharge of any pollutant into a navigable water. Organization - a persons’ affiliation or place of employment. Permit Application - a set of documents that must be submitted to the DNR to apply for an NPDES permit. There are four categories of permit applications:  Pending permit application – an NPDES permit application that has not yet been completed by an applicant and has not yet been submitted to a permit writer. A pending application is pre-filled by a permit writer and completed by an applicant.  Submitted permit application – a permit application that has been completed by an applicant and submitted by an applicant to a permit writer, but that has not yet been reviewed by a permit writer.  Completed permit application – a permit application that has been submitted by an applicant to a permit writer and has been reviewed and accepted as a complete permit application by a permit writer.  New permit application – if an applicant wishes to submit a permit application for a new facility, it is saved in the system as a new permit application. The new permit applications will be submitted to the application administrator. Permit Number – a seven-digit number assigned by NPDES staff to an individual permit. Permit Type  Agricultural – an NPDES permit issued to an animal feeding operation (AFO).  Industrial – an NPDES permit issued to an industrial wastewater treatment facility.  Municipal – an NPDES permit issued to a municipal wastewater treatment facility.  Municipal WT – an NPDES permit issued to a municipal water treatment facility.

Operation – a permit authorizing the operation of a wastewater facility. Semi-public – an NPDES permit issued to a semi-public wastewater treatment facility, which is not owned by a private entity, city, sanitary sewer district, or a designated and approved management agency. Stormwater – an NPDES permit issued to a facility for the discharge of stormwater.

Permit Status - see definitions for Draft Permit and Final Permit. Permit Writer - a DNR staff person who writes NPDES permits. Public Notice Date – the date a draft permit is placed on public notice by a permit writer. Public Viewer – a member of the public who can search NPDES permit online but is not a registered user. Receiving Stream – The waterbody that a permitted facility discharges to. Region – DNR has six regional Field Offices that serve different portions of the state, northeast, north central, northwest, southwest, south central, and southeast. Contact information for each of the regional field offices can be accessed on the main DNR webpage Registered Applicant - a registered user with the rights to complete a permit application. An applicant can also save searches and comment on draft NPDES permits. Registered Signatory - a registered user with the rights to submit a permit application. A signatory can also save searches and comment on draft NPDES permits. Registered User - a member of the public who has registered on the system and who can save searches and comment on draft NPDES permits. River – The waterbody that a permitted facility discharges to; same as receiving stream. Role Entity – a description of the role of a person within a business or organization. The role entity may be the same as a job title. Stream Designation – The stream designation identifies which uses a waterbody is protected for. Protected uses are those general uses and designated uses that apply to Iowa's surface waters. All surface waters in Iowa are afforded protection for general uses; selected waterbodies are classified for designated uses and are afforded additional protection.  General Uses: General Use are to be protected for livestock and wildlife watering, aquatic life, noncontact recreation, crop irrigation, and industrial, domestic, agricultural, and other incidental water withdrawal uses.  Designated Uses: These are waterbodies which maintain flow throughout the year or contain sufficient pooled areas during intermittent flow periods to maintain a viable aquatic community. Designated use waters are to be protected for all uses of general use segments in addition to the specific uses assigned. Designated use segments include: A. Recreational (Class ―A‖) uses: Waters designated for Class ―A‖ uses are protected for various contact recreational uses.

Primary contact recreational use (Class ―A1‖): waters in which recreational or other uses may result in prolonged and direct contact with the water. (ii) Secondary contact recreational use (Class ―A2‖): waters in which recreational or other uses may result in contact with the water that is either incidental or accidental. (iii) Children’s recreational use (Class ―A3‖): waters in which recreational uses by children are common. B. Aquatic Life (Class "B") uses: Waters designated for Class "B" uses are protected for wildlife, fish, aquatic and semi-aquatic life uses. Class "B" waters are divided into the following categories: (i) Cold water aquatic life—Type 1 (Class ―B(CW1)‖): Waters in which the temperature and flow are suitable for the maintenance of a variety of cold water species, including reproducing and nonreproducing populations of trout and associated aquatic communities (ii) Cold water aquatic life—Type 2 (Class ―B(CW2)‖). Waters that include small, channeled streams, headwaters, and spring runs that possess natural cold water attributes of temperature and flow. These waters usually do not support consistent populations of trout, but may support associated vertebrate and invertebrate organisms. (iii) Warm water—Type 1 (Class ―B(WW-1)‖). Waters in which temperature, flow and other habitat characteristics are suitable to maintain warm water game fish populations along with a resident aquatic community that includes a variety of native nongame fish and invertebrate species. These waters generally include border rivers, large interior rivers, and the lower segments of medium-size tributary streams. (iv) Warm water—Type 2 (Class ―B(WW-2)‖). Waters in which flow or other physical characteristics are capable of supporting a resident aquatic community that includes a variety of native nongame fish and invertebrate species. The flow and other physical characteristics limit the maintenance of warm water game fish populations. These waters generally consist of small perennially flowing streams. (v) Warm water—Type 3 (Class ―B(WW-3)‖). Waters in which flow persists during periods when antecedent soil moisture and groundwater discharge levels are adequate; however, aquatic habitat typically consists of nonflowing pools during dry periods of the year. These waters generally include small streams of marginally perennial aquatic habitat status. Such waters support a limited variety of native fish and invertebrate species that are adapted to survive in relatively harsh aquatic conditions. (vi) Lakes and wetlands (Class ―B(LW)‖). These are artificial and natural impoundments with hydraulic retention times and other physical and chemical characteristics suitable to maintain a balanced community normally associated with lake-like conditions. C. Drinking Water (Class "C") uses: Waters which are used as a raw water source of potable water supply.  Other Designated Uses: Other designated uses include: A. High Quality water (Class ―HQ‖): Waters with exceptionally better quality than specified by Iowa water quality criteria and with exceptional recreational and ecological importance. Special protection is warranted to maintain the unusual, unique or outstanding physical, chemical, or biological characteristics that these waters possess. B. High Quality Resource water (Class ―HQR‖): Waters of substantial recreational or ecological significance that possess unusual, outstanding or unique physical, chemical, or biological characteristics that enhance the beneficial uses and warrant special protection. C. Human health (Class ―HH‖). Waters in which fish are routinely harvested for human consumption or waters both designated as a drinking water supply and in which fish are routinely harvested for human consumption. (i)

 Older designated uses: When a permit has not been reissued for several years, older stream designations may still be listed. Some of the common older designations are: A. Class "B(WW)‖ (significant resource warmwater): lakes or rivers which support warmwater game fish and associated aquatic communities, including sensitive species. B. Class "B(LR)‖ (limited resource warmwater): streams which support limited aquatic life populations primarily composed of minnows and other nongame fish species. Title - a persons’ job title at their place of employment.
