XX-DEC-1974 — The federal Safe Drinking Water Act (SDWA) enacted to ensure safe drinking water for the public; the Environmental Protection Agency (EPA) is responsible for setting safety standards, monitoring, compliance and enforcement of the same under the SDWA.
07-JUN-1991 — EPA issued the Lead and Copper Rule (LCR) limiting the amount of lead and copper in public drinking water, as well limiting the permissible amount of pipe corrosion occurring due to the water itself.
XX-JUL-1998 — The federal Environmental Protection Agency required all large public water systems maintain a program to monitor and control lead in drinking water due to piping corrosion under the Lead and Copper Rule (LCR). Cities like Flint must have a state-approved plan to maintain water to regulatory limits for pH, alkalinity, corrosion inhibitor chemicals.
XX-XXX-2002 — [DATE TBD] Genesee County purchased 326 acres of property with 300 feet of Lake Huron waterfront via auction from Detroit Edison, for $2.7 million **How did this purchase affect the city of Flint’s 2002-2004 financial crisis?
28-AUG-2009 — Michigan Department of Environmental Quality (MDEQ) issued a permit to Genesee County Drain Commission for water withdrawal from Lake Huron (Permit 2009-001), up to 85 million gallons per day. MDEQ director at the time is Steven Chester.
10-MAY-2011 — DTE Energy expressed interest in acquiring 3 million gallons of water from Lake Huron intake for use at the Greenwood electricity generation plant.
07-SEP-2011 — Report to Flint City Council by Rowe Engineering determined buying water from Karegnondi Water Authority (KWA) cheaper than continuing to purchase from Detroit Water and Sewerage Department (DWSD), or using Flint River water as upgrades to Flint treatment equipment required would cost $50 million.
XX-SEP-2011 — (confirm date) City of Flint increase water and sewer rates 35%. Higher water costs due in part to higher-than-expected unmetered water losses. This is the second double-digit rate hike in 2011. The city’s water system once served ~200K residents, now serves half that number and a much smaller manufacturing base.
29-NOV-2011 — Emergency Manager Michael Brown appointed by Gov. Rick Snyder to take over management of the city of Flint effective 01-DEC-2011. Democratically elected offices are now subordinate to the EM.
XX-DEC-2011 — (confirm date) Report showed the City of Flint leaking 30 to 40% of its water, well above more typical 15-20 percent loss of unmetered water.
20-DEC-2011 — The City of Detroit sells $500,675,000 in bonds for Water Supply System Revenue funding (pdf). The offering prospectus notes Flint’s desire to migrate to the KWA, but that it might be seven years out before the move. 6% of DWSD water is supplied to Flint.
XX-FEB-2012 — (confirm date) Emergency Manager’s team audited Flint’s water system to identify current rate of unmetered water loss.
23-APR-2012 — EM Michael Brown proposed budget plan includes a 25% average increase in water and sewer rates, with water rates projected to increase 12.5% and sewer 45%. City personnel cuts were also proposed. Water and sewer are the single largest expenditure in the budget. (Proposed budget, PDF) **Did any of the personnel cuts made affect staffing of water and sewer maintenance?
XX-AUG-2012 — [DATE TBD] Emergency Manager Ed Kurtz appointed by Gov. Rick Snyder after Brown steps down. Kurtz has previous experience working in Flint during the 2002-2004 financial emergency.
XX-DEC-2012 — [DATE TBD] Michigan Treasury officials met with Flint city officials to discuss drinking water alternatives, including Flint River. Only two options — remaining on DWSD, or development/switch to new KWA — would be studied.
