When: Friday, February 8, 2019
Time: 8:00 AM - 5:00 PM (Registration begins at 7:30 AM). Please note: breakfast and lunch are included.

Location: DoubleTree Hotel, 5400 Computer Drive, Westborough, MA

Pricing: $300 Members | $450 Non-Members
Instructors: Jane Parkin Kullmann, Senior Risk Assessor, Wood Environment & Infrastructure Solutions, Inc. and Bernard J. Morzuch, Department of Resource Economics, University of Massachusetts
Credit: This course has been approved for 8.0 LSP "non-DEP"/Technical continuing education credits (#1518A). This course will also be submitted to the CT LEP Board for credits. This is a new course.  

Course Description: 
MassDEP has stated that they plan to propose revisions to the Exposure Point Concentration (EPC) section of the MCP at 310 CMR 40.0926. Under the current MCP, a data set’s maximum concentration level, its arithmetic average, or its 95th percentile upper confidence limit (UCL) can be used to estimate an EPC. It is anticipated that the MCP revisions may separate Disposal Sites into categories of “simple” and “complex,” with options that would be available for each category for calculating an EPC. Because complex sites are characterized by contamination that is likely to be dispersed and therefore highly variable, the LSPA expects that MassDEP may  likely require more rigorous data evaluations, including the use of a 95% UCL as an EPC, for these sites. To prepare you for these possible changes to the MCP and familiarize you with 95% UCLs, this course will summarize 1) how 95% UCLs are calculated, 2) how you can calculate 95% UCLs using freely available software, and 3) how to apply 95% UCLs in your work as an LSP (or for other professional services), including use of the 95% as an EPC for a risk characterization. 

The course will also address a variety of methodological issues, all of which are necessary for calculating and understanding the 95% UCL. In addition to data-distribution issues, we will address problems commonly encountered with environmental data: censored data; non-detects; attempting to make reliable inferences based on small sample size. We will apply the 95% UCL methodology to a variety of data sets, each focusing on a different problem or issue. We will use the ProUCL software (a free software for PCs developed by USEPA) to perform the calculations.  We will analyze and interpret the ProUCL output based on what we learned earlier in the course.

Participants should bring a laptop with ProUCL installed ( Note that ProUCL is only available for PCs.

Participants will be asked to do calculations on their own as well as watch the instructors demonstrate calculations.

Course Prerequisites:
It is helpful but not required that participants have a working knowledge of key descriptive statistics such as mean, median, mode, range, variance, and standard deviation. Familiarity with the z-table and t-table for the purpose of calculating probabilities is desirable. Familiarity with the Central Limit Theorem is desirable but not expected.
