fason, LDO staff may need to reference source water assessments to complete this assignment. Can you send me a copy of the assessment for each of these supplies mentioned below? Thanks. | may add to the list as needed. Michael Prysby, PE. District Engineer Office of Drinking Water and Municipal Assistance 517 290-8817

Jason, | scrolled through the Flint assessment several times and did not see lat...long. Cooridinates for the intake....and only very basic mention of its construction....so I’m not sure where to edit... couldn’t see where you made edits in the St. lg. Assessment. Call me before 2 if you get a chance...perhaps I’m missing something. Thanks Michael Prysby, P.E. District Engineer Office of Drinking Water and Municipal Assistance 517 290-8817

You may wart to consider the idea of providing an edited copy of the report thal rernoves the intake location and specs. | have done this before when there is a request for a community's assessment. Are there any concerns there?

Mike, You may want to inquire why they don’t have a copy of this record as itis a requirernent. in addition, per the required OCR language they are supposed to make it available to their customers upon request. We should also have a copy of this sornewhere in the basic data files. Stephen Busch, PLE. Lansing and Jackson District Supervisor Office of Drinking Water and Municipal Assistance MDEQ.

Jason, Has a source water assessment been performed for the Flint River watershed...spec. for the Flint WTP intake? If so, the city of Flint would like to obtain a copy of source water assessment report. xxxEND_PAGE:deq16_b5_0892_4900_0814 Michael Prysby, P.E.

Yes, the Sault Ste. Marie intake is in a connecting channel, but not part of the flow analysis as described below. Yes, there was a CAZ and assessment on the Flint Intake, see below: There may not be a need, but there is some good information available in the assessment. We should be assessing our new intakes, however, it’s quite a project to complete following the protocol. Set aside $’s?? xxxEND_PAGE:deq03_b606_3718_4178_379 \ $ ee bile, Para 9 | Explanation {He Flint Water-supply Intake @ Lakes A Polantial Contaminant Source (PCS) Critical Assessment Zone = BWA Boundary Susceptible Area ~—~ Rivers and Craaks

Not that it matters for your discussion, but Sault Ste. Marie is also in a connecting channel. Maybe DeTour as well? 2 xxxEND_PAGE:deq03_b606_3718_4178_380 Did we ever develop a CAZ for the Flint River? Do we need to if it will only be a rarely used, emergency intake in another 18 months?

Hi Kevin, The assessment methodology for the intakes is slightly different based on the three surface water supply types. There are approximately 55 Great Lakes intakes, 14 Great Lakes connecting channel intakes, and 8 inland river intakes. The Great Lakes (55) and connecting channels intakes (14) used the “Assessment Protocol for Great Lakes Sources” which was developed by a Region 5 states workgroup in August 2000. Your statement was correct on the two factors used to calculate sensitivity of each intake is length (L) of the intake pipeline and depth (D) of the intake structure. Sensitivity equals L x D as a unit less value. Sensitivity < 25k has a CAZ radius of 3000 feet, 25k — 125k with radius of 2000 feet, and >125k a radius of 1,000 feet. The other factors you mentioned contributing to the CAZ, as well potential contaminant sources, discharges, and water quality are taken into consideration with the Sensitivity analysis to determine an overall Susceptibility of the intake. The connecting channel intakes (approx. 14) from roughly Port Huron to Wyandotte also utilized a flow model analysis of the St. Clair — Detroit River Waterway. This program included MDEQ, USGS, USACE, USEPA, and DWSD. This helped to identify concerns in contaminant tracking and develop contingency plans. The inland river intakes (approx. 8) were watershed based assessments. In addition to the CAZ based on a Sensitivity analysis, these assessments identified buffers in the watershed upstream of the intake. These 300-foot buffers or susceptible areas were created along the shoreline of all drainages upstream of the intake. These were additional areas to identify potential risks or contaminant sources. | attached an example of a watershed based assessment for Blissfield. More source water assessment program information is available on our website at: 3675 3693---,00.html Also, we should meet to follow up on our water quality standards comparisons for our programs and proceed with the integration toolkit. | will be in Lansing tomorrow and again on February 18".

Hi Jason — Was going to give you a call this p.m. to discuss some CAZ ‘stuff’ — but looks like you’re out of the office. Until we can talk —| wanted to see if the description below (quoted), which is currently in our Assessment Methodology of the Integrated Report, is relevant to inland surface water intakes as well (e.g. Raisin River)? This language is worded relative to Great Lakes/Connecting Channels, but based on the GIS layer we have (which I’m told came from the drinking water program originally) it looks like a similar approach is applied inland perhaps. “For public water supply intakes that are located in the Great Lakes or connecting channels, a concept of a Critical Assessment Zone (CAZ) around each intake was developed based on a Sensitivity Factor calculated for each intake. The two attributes used to develop the Sensitivity Factor are the water depth above the intake structure and the perpendicular distance from shore or length of the intake pipeline. Other factors such as localized flow patterns, thermal effects, wind effects, lake bottom characteristics, benthic nepheloid layers, etc., may be used to complete the sensitivity analysis. A radius for the CAZ, ranging from 3,000 feet for the most sensitive intakes to 1,000 feet for the least sensitive intakes, is assigned based on the Sensitivity Factor. A shape with this radius is then drawn around the intake to illustrate the CAZ. If the CAZ intersects the shoreline, then the geographic extent of the assessment unit is determined on a case-by-case basis as the most influential 12-digit HUCs that are along the shoreline within the CAZ. For intakes that are located in open waters of the Great Lakes where the CAZ does not intersect the shoreline, the geographic extent of the assessment unit is 1.5 square miles.” That said, | seem to remember from a Source Water Protection standpoint that anything ‘upstream’ was considered? If so, I’m just trying to wrap my head around how that differs from a CAZ...(and if not, well...’m wrong, which is likely). It'd be helpful to chat if you have some time in the next day or so.

Steve and Mike were the first ones on the agenda, which was fortunate in thet the audience was still relatively civil.

Pm sure we are all aware of the issue, but Flint is on the front page of the Detrot Free Press today. Jason Berndt Environmental Quality Analyst Office of Drinking Water and Municipal Assistance Gaylord Field Office 547-284-6542 989-705-3420 xxxEND_PAGE:deq21_b535_1525_1525_1

We do good work, One thing missing from the list belaw was Chuck’s note that one of our accomplishments should be that ne serious public health problems arose in the public water supply program in the past year. However, it is difficult to quantify “nothing bad happened.”

Dana, | have attached the 2011 CD report. | would like to be able to provide a draft of the 2012 report for Liane’s review by December 17'" or so. Please take a look at the sections that identify or target the non-community systems. Primarily that includes the technical assistance, program efforts, training, and identifying needs/areas the program has provided additional assistance. We did talk about including some data on sanitary surveys and permits. If you want to edit this copy, | can use that to copy and paste after your changes. Let me know if you have questions.

Diane/Connie: Attached is the draft report and a cover letter. There were some edits and corrections. They are located at: S:\Drinking Water and Environmental Health\Community Drinking Water\Capacity Development\Annual Report\The Reports\201 1 Please be sure to use the diane review document and we should later delete the other copy of the report. This must be submitted to EPA by December 31st, so we have some time for managment review and submittal. xxxEND_PAGE:deq26_b006_0080_0080_1

Attached is a draft copy ready for your review and comments. Thanks to Jean, as well, for helping write portions of this report and appendices. | would like to have comments incorporated and back to Diane/Connie before the end of next week, if possible. xxxEND_PAGE:deq26_b004_0052_0052_1
