EPA's Office of Policy, Planning and Evaluation. PIPQUIC is a
fully-integrated data base combining air, water, hazardous waste, and
health risk data. It contains pollutant source data for the specific
geographic areas of Philadelphia, Baltimore, Santa Clara, Rhode Island,
and Kanawha Valley, West Virginia. In addition, PIPQUIC provides
user-friendly interactive gateways to several EPA data bases (CDS, NEDS,
PCS, STORET, KWOHS and FINDS).
PIPQUIC Is designed for users with no previous computer experience
and allows them to systematically analyze extensive data traditionally
stored In the separate, media-specific data bases. PIPQUIC supports all
phases of environmental management: problem identification, planning,
regulatory development, program Implementation and results evaluation.
PIPQUIC tools include environmental profiles (e.g., rank sources of air
or water pollution); exposure and risk analyses (e.g., pinpoint
culpability for modeled pollutant concentrations and risk); and
what-if" analyses (e.g., evaluate alternative pollution control
strategies).
PIPQUIC; Baltimore study area
For major industrial surface-water dischargers into the Patapsco
River and Baltimore Harbor, PIPQUIC retrieved data from EPA's PCS to
profile flow, total suspended solids, and 100 toxic compounds. Loadings
were computed by multiplying flow times concentration where loading data
were not available. PIPQUIC also Integrated extensive Discharge
Monitoring Report (OMR) data collected from Industry files, that had not
been previously Incorporated Into any automated system. Finally, a
model based on the National Urban Runoff Program (NURP) was used with
PIPQUIC to estimate seasonally-adjusted non-point toxic discharges.
Indirect discharge (pretreatment) data from the Baltimore Water
Department was also acquired and and added to the data base. Hazardous
waste data from Maryland's Hazardous Waste Manifest System as well as
EPA's Hazardous Waste Data Management System were also made available
through PIPQUIC.
The Integrated air emissions data Include Maryland's toxics
Inventory for major point sources and estimated toxic organic emissions
for minor point sources. These data were accessed from Maryland's Air
Registry System and Incorporated a set of emission factors developed by
EPA's Office of Air Quality Planning and Standards. For boilers and
sewage treatment plants, AMS added detailed emissions estimates provided
by another contractor. The Hazardous Emissions Model and Integrated
System (HEHIS), a state-of-the-art national data base of county-level
emissions estimates was used to provide data on impacts such as gas
marketing; road vechiles; waste oil burning; residential, industrial,
commercial heating; cooling towers; and agricultural burning.
A profile of the point sources of pollution in the Patapsco
River
In the Patapsco River Basin there are 28 NPOES municipal dischargers
with only four of those being majors (discharging more than 1 MGO). Of
the 186 NPDES Industrial dischargers, 31 discharge more than 1 MGO
