Interns can perform field work
The New Jersey Department of Environmental Protection (DEP) developed the Municipal Stormwater Regulation Program in response to the Phase II rules issued by the U.S. Environmental Protection Agency in 1999. The New Jersey program addresses pollutants entering the state's waters from certain storm drainage systems owned or operated by local, county, state, interstate, or federal government agencies.
The DEP issued New Jersey Pollutant Discharge Elimination System Permits to highway agencies and public complexes and municipalities throughout the state. Public complexes include large public colleges, prisons, hospital complexes, and military bases. Highway agencies include county, state, interstate, or federal government agencies that operate highways and other thoroughfares, such as each of the 21 counties, the New Jersey DOT, Port Authority of New York and New Jersey, the New Jersey Turnpike Authority, and the South Jersey Transportation Authority.
The regulations add a new requirement for New Jersey's 562 municipalities, many of them relatively small townships with limited budgets. Paul Horta, P.L.S., town surveyor for West-field, N.J.—population 30,000—and his four-person engineering department have responsibility for maintaining and updating tax parcel maps, reviewing plans, and coordinating stake-out work for road construction and maintenance. Increasingly, they also are being tasked with CIS projects, such as mapping fire hydrants and manhole covers, and most recently the stormwater outfall mapping requirement.
Horta reports that he is using a summer intern to do much of the field work of data collection using the Leica Geosystems' GS20 and real-time WoRCS differential data for submeter positioning accuracy. He says the field equipment is so easy to learn that a summer intern can quickly get up and running with minimal training.
