Minnesota Statewide Screening IT solution – MPCA View
Lakes Environmental has completed the first phase of the development of the Minnesota Statewide Screening IT solution. This system analyzes the impacts of all atmospheric air toxics in the Minnesota Pollution Control Agency (MPCA) emissions inventory. The sources of air pollutants include point and non-point sources. Major point sources usually are blamed by pollution, but the accumulation of on-road traffic emissions, area sources (gas stations, dry cleaner, use of solvents and paints, etc.), agricultural emissions (pesticides, ammonia, and methane release from animals), and forest fires (prescribed and wild fire) can be much larger than industrial sources.
To achieve MPCA’s objectives Lakes Environmental has implemented a system with the following components:
- A complete air emissions information management system.
This extensively tested component is based on the EI View architecture,
which is part of emissions data system in Wyoming, Arizona, Nevada,
Las Vegas, and Reno, among others.
- A GIS-based visualization system. This system allows for the verification
of data accuracy and interpretation of results.
- An automatic air dispersion modeling (ADM) component that extract the
source location and parameter, uses a Universal Grid to place ADM grid nodes,
creates all the necessary input files, process the runs, and display results.
- A multi-pathway multi-source risk assessment component that estimates
the human health impacts. This system can track back impacts from specific sources and specific chemicals.
- A super-computer grid system to allow for the use of all the computers available at MPCA,
when these are not in full use. For example, all the computers can be processing in parallel from
6:00PM to 7:00AM every work day, and full time on the weekends.
This past April 27th and 28th 2005, U.S. EPA representatives met at the MPCA to peer review MPCA View applicability and acceptability for the proposed objective. This peer review is schedule to last 90 days.
MPCA is a leading environment agency in investigating cumulative impacts from multiple sources. Lakes Environmental feels fortunate to be able to support the MPCA on this research project.
