NPDES PERMIT. National Pollutant Discharge Elimination System permit now or hereafter held by the town and setting forth conditions for the discharge of any pollutants or combination of pollutants.

NUISANCE. Any substance which is injurious to health or offensive to the senses or an obstruction to the free use of property so as to interfere with the comfort or enjoyment of life or property.
OPERATION AND MAINTENANCE. All expenses related directly to operating and maintaining the sewage works, as identified in the “Uniform System of Accounts for Wastewater Utilities” or as prescribed by the Indiana State Board of Accounts under the general headings, Plant Operation and Maintenance, Sewer Operation and Maintenance, Customer Accounts, Administrative and General, Insurance and Taxes.

REPLACEMENT is included in operation and maintenance. See OPERATION AND MAINTENANCE.
SANITARY SEWAGE. Sewage such as, and having the characteristics of, domestic sewage from dwellings (including apartment houses and hotels), office buildings, factories or institutions, free from storm and surface water and industrial wastes.
SEWER. A pipe or conduit laid for carrying sewage or other liquids and solids suspended or entrained therein.
