U.S. EPA Releases New BPIP-PRIME Model
On Dec. 9th 2004, the U.S. EPA released a new version of the BPIP-PRIME model (BPIPPRM version 04274). The storage limit values for the BPIP-PRIME model have changed and are now unlimited for the number of buildings, tiers, corners, and stacks. In addition, two new processing switches were added so that BPIPPRM can also output BPIP output in ST and LT formats. For detailed information, please see the BPIPPRM Model Change Bulletin at:

Lakes Environmental Software News & Updates
Lakes Environmental Software has released version 4.8.6 of ISC-AERMOD View. This upgrade was released primarily to incorporate the changes made to the U.S. EPA BPIP-PRIME model.

First Statewide Multi-Pathway Risk Assessment Completed
Lakes Environmental has developed an easy-to-use, robust system to facilitate screening level human health risk assessments of sites located within a state. The GIS-enabled system can incorporate sources from most current emission inventory data for point, area, non-road and on-road mobile sources. Using the state’s other existing meteorology and source databases, StateRisk View performs air dispersion modeling across the entire state. Air dispersion modeling results are then used in conjunction with additional geophysical GIS data to perform state-wide multi-source, multi-pathway risk assessment. For more information please see the full details at:

Lakes Environmental Services
MM5 Meteorological modeling to obtain more accurate wind fields is now a reality. This type of service will help you to fill in the missing data and provide a better initial wind field for CALMET (CALPUFF). In addition to providing more defensible results, MM5 is also an indispensable tool when modeling over complex terrain. For more information please contact us at: services@weblakes.com.

New BPIP Prime Changes
Users of the U.S. EPA BPIP PRIME model have noticed occasional results, which are different from previous versions. The reason for such discrepancy is that the new version has two bug corrections. Previously, BPIP-PRIME had two faulty assignments described in the Model Change Bulletin. In the Model Change Bulletin #1 for the new BPIPPRM there is a description of a bug correction about one page before the end that reads as follows:
" (open quote) The following two variables were erroneously equated and were changed from:
MPADX(S,D) = PBL
MPADY(S,D) = PBL
to:
MPADX(S,D) = XBADJ
MPADY(S,D) = YBADJ " (end quote)
The Model Change Bulletin (MCB) also describes a second bug correction (about 2/3 of the way through the MCB) that states as follows:
" (open quote) An error was found where DPADY(S) was repeated twice instead of
as DPADX(S, DPADY(S). The code was changed from:
+ DPADY(S),DPADY(S)
to:
+ DPADX(X),DPADY(S)
" (end quote).
Therefore, the numerical differences from the old to the new BPIP-PRIME is a result of two bug corrections, not of new bugs.

BEIJING - Polluted Beijing is planning to clean up its
act by planting grass on rooftops, Xinhua news agency said on Monday. The gardening campaign was part of the Chinese capital's drive to improve air quality in time for the 2008 Olympics, it said. "Downtown Beijing is too crowded to insert more green belts, so we'll try it on the roofs," Yang Zhihua, an official with the city's parks and woods bureau, was quoted as saying. Green belts are urban areas set aside for planting trees and shrubs.
