As used in this article, the following terms shall have the meanings indicated:
ABUTTERThe owner(s) of land abutting the activity.
ALTERATION OF DRAINAGE CHARACTERISTICSAny activity on an area of land that changes the water quality, force, direction, timing or location of runoff flowing from the area. Such changes include: change from distributed runoff to confined, discrete discharge; change in the volume of runoff from the area; change in the peak rate of runoff from the area; and change in the recharge to groundwater in the area.
APPLICANTAny person, individual, partnership, association, firm, company, corporation, trust, authority, agency, department, or political subdivision of the commonwealth or the federal government to the extent permitted by law requesting a stormwater management permit for proposed land disturbances.
APPLICANT'S TECHNICAL REPRESENTATIVEA registered professional engineer (P.E.) hired by the applicant to certify that design and construction are completed in accordance with the applicable local, state, and federal stormwater requirements.
AUTHORIZED ENFORCEMENT AUTHORITYThe Town's authorized agent to enforce construction and post-construction runoff controls as specified in this Article
II and the stormwater management rules and regulations. The Conservation Commission is designated as the authorized enforcement authority.
BEST MANAGEMENT PRACTICE (BMP)An activity, procedure, restraint, or structural improvement that helps to reduce the quantity or improve the quality of stormwater runoff.
BYLAWRefers to Chapter
213, Stormwater Management, of the Town of Lynnfield Charter and Bylaws.
CERTIFIED PROFESSIONAL IN EROSION AND SEDIMENT CONTROL (CPESC)A certified specialist in soil erosion and sediment control. This certification program, sponsored by the Soil and Water Conservation Society in cooperation with the American Society of Agronomy, provides the public with evidence of professional qualifications.
CLEAN WATER ACTThe Federal Water Pollution Control Act (33 U.S.C. §
1251 et seq.), as hereafter amended.
CLEARINGAny activity that removes the vegetative surface cover.
DEVELOPMENTThe modification of land to accommodate a new use or expansion of use, usually involving construction.
DISCHARGE OF POLLUTANTSThe addition from any source of any pollutant or combination of pollutants into the municipal storm drainage system or into the waters of the United States, the commonwealth, or the Town of Lynnfield.
EROSIONThe wearing away of the land surface by natural or artificial forces such as wind, water, ice, gravity, or vehicle traffic and the subsequent detachment and transportation of soil particles.
EROSION AND SEDIMENT CONTROL PLANA document containing narrative, drawings, and details developed by a registered professional engineer (P.E.) or a certified professional in erosion and sediment control (CPESC), which includes BMPs or equivalent measures designed to control surface runoff, erosion and sedimentation during pre-construction and construction-related land disturbances. The plan is required as part of the application for a stormwater management permit.
GRADINGChanging the level or shape of the ground surface.
IMPERVIOUS SURFACEAny material or structure on or above the ground that prevents water infiltrating the underlying soil. Impervious surface includes without limitation roads, paved parking lots, sidewalks, and rooftops.
LAND DISTURBANCEAny action that causes a change in the position, location, or arrangement of soil, sand, rock, gravel, or similar earth material.
MASSACHUSETTS STORMWATER MANAGEMENT STANDARDSThe Stormwater Standards as further defined by the Massachusetts Stormwater Handbook both issued by the Department of Environmental Protection, and as amended, that coordinate the requirements prescribed by state regulations promulgated under the authority of the Massachusetts Wetlands Protection Act, MGL c. 131, §
40, and Massachusetts Clean Waters Act, MGL c. 21, §§
23 through
56. The Standards address stormwater impacts through implementation of performance standards to reduce or prevent pollutants from reaching water bodies and control the quantity of runoff from a site.
