For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   AGRICULTURAL LAND DISTURBING ACTIVITY. Tillage, planting, cultivation, or harvesting operations for the production of agricultural or nursery vegetative crops. The term also includes pasture renovation and establishment, the construction of agricultural conservation practices, and the installation and maintenance of agricultural drainage tiles. For the purposes of this subchapter, the term does not include land disturbing activities for the construction of agricultural-related facilities such as barns, buildings to house livestock, roads associated with infrastructure, other infrastructure, agricultural waste lagoons and facilities that process residential, workshop, or human wastes, and lakes, pond, and wetlands; and other infrastructure.
   CLEARING. Any activity that removes the vegetative surface cover.
   CONSTRUCTION ACTIVITY. Land disturbing activities and land disturbing activities associated with the construction of infrastructure and structures. This term does not include routine ditch or road maintenance or minor landscaping projects.
   CONSTRUCTION PLAN. A representation of a project site and all activities associated with the project. The plan includes the location of the project site, buildings, and other infrastructure, grading activities, schedules for implementation, and other pertinent information related to the project site. A stormwater pollution prevention plan is a part of the CONSTRUCTION PLAN.
   CONTRACTOR or SUBCONTRACTOR. An individual or company hired by the project site owner, by an individual lot owner, or by an individual lot operator to perform services on, or connected to, the project site or individual lot.
   DEVELOPER. Any person financially responsible for construction activity; or an owner of property who sells or leases, or offers for sale or lease, any lots in a subdivision.
   EROSION. The detachment and movement of soil, sediment, or rock fragments by water, wind, ice, or gravity.
   EROSION AND SEDIMENT CONTROL MEASURE. A practice, or a combination of practices, to control erosion and resulting sedimentation.
   EROSION CONTROL. A measure that prevents erosion.
   LAND DISTURBANCE OR LAND DISTURBING ACTIVITY. Any human-made change of the land surface, including removing vegetative cover that exposes the underlying soil, excavating, filling, transporting, and grading.
   MEASURABLE STORM EVENT. A precipitation event that results in a total measured precipitation accumulation equal to, or greater than, one-half inch of rainfall.
   PROJECT SITE. The entire area on which construction activity is to be performed.
   PROJECT SITE OWNER. The person required to submit the NOI letter per 327 I.A.C. 15-5 and required to comply with the terms of this subchapter and 327 I.A.C. 15-5, including a developer; or a person who has financial and operational control of construction activities and project plans and specifications, including the ability to make modifications to those plans and specifications.
   SEDIMENT. Solid material (both mineral and organic) that is in suspension, is being transported, or has been moved from its place of origin by air, water, gravity, or ice and has come to rest on the earth’s surface.
   SEDIMENT CONTROL. Measures that prevent sediment from leaving the project site.
   SOIL. The unconsolidated mineral and organic material on the surface of the earth that serves as the natural medium for the growth of plants.
   SOIL AND WATER CONSERVATION DISTRICT (SWCD). A political subdivision established under I.C. 14-32.
   STORMWATER POLLUTION PREVENTION PLAN (SWPPP). A plan developed to minimize the impact of stormwater pollution resulting from construction and post-construction activities. The plan indicates the specific measures and sequencing to be used to control sediment, soil erosion, and other construction site wastes during and after construction.
   STORMWATER QUALITY MEASURE. A practice, or a combination of practices, to control or minimize pollutants associated with stormwater runoff.
   TECHNICAL REVIEW AND COMMENT FORM. A form issued by the town’s wastewater utility stating that the Stormwater Pollution Prevention Plan is adequate or stating revisions needed in the SWPPP.
   TOWN’S WASTEWATER UTILITY. Employees or designees of the Director of the town’s wastewater utility designated to enforce this subchapter.
   TRAINED INDIVIDUAL. An individual who is trained and experienced in the principles of stormwater quality, including erosion and sediment control as may be demonstrated by state registration, professional certification, experience, or completion of coursework that enable the individual to make judgments regarding stormwater control or treatment and monitoring.
   WATER QUALITY VOLUME (WQv). The storage needed to capture and treat 90% of the average annual stormwater runoff volume. Numerically, WQv will vary as a function of long-term rainfall statistical data.
