FYI from Lake Watch

Now that summer is in full swing, Lake Watch volunteers are back to work providing twice-a-month water quality testing at sites across Lake Martin. Results of our bacteriological testing are posted to the Lake Watch Swim Alert webpage at Lakewatch.org/swim-alert and to the Alabama Water Watch statewide database at aaes.auburn.edu/ alabamawaterwatch. Our testing this season confirms excellent water quality throughout Lake Martin; however, if our testing does identify areas on the lake that do not appear to meet ADEM safe swimming standards, that information can be used by persons recreating on the lake to make their safe swimming decisions.

Waterfowl at swimming areas may produce unsafe conditions

Lake Watch monitors water quality at numerous swimming beach sites across Lake Martin, including the beach at one popular restaurant in the lower lake where geese and ducks may often be present in significant numbers. Some patrons delight in feeding the waterfowl and turtles at this swim beach. At this site, Lake Watch monitors identified E. coli levels above the ADEM safe swimming limit on two occasions in the 2022 swim season and again in May 2023. Presence of waterfowl, particularly Canada geese in significant numbers, could be expected to produce fecal contamination at a swim beach, be it public or private. Also, be aware that E.coli would persist in the sediment for a fairly long time after the geese have left.

Canada geese are magnificent creatures. Most of us delight to see them on Lake Martin and believe that the resident population is at a healthy natural level. Lake Watch inquired at the Alabama Department of Conservation and Natural Resources, Wildlife and Freshwater Fisheries Division. They referred us to a very thorough article on their website addressing the problem presented by Canada geese. On page one, this article offers a control measure, “Ban public feeding of geese,” as the first listed item under Habitat Modification.

Oversight of upcoming industrial discharge from Alabama Graphite Products, LLC

Lake Watch

Lake lovers need to make their own informed decisions about wildlife management and when and where to swim. Lake Watch recommends that lake lovers discourage the presence of geese at their swim areas. We all know that this is easier said than done. Geese are very persistent about getting to a food source, such as a nice green lawn or fruit trees near the water. Above all, feeding of food pellets and table scraps is discouraged.

It is understood that the Alabama Department of Environmental Management has issued a State Indirect Discharge Permit to Alabama Graphite Products, Inc., at Lake Martin Regional Industrial Park in Kellyton. AGP will produce a coated spherical graphite product to be used primarily in electric vehicle batteries. AGP is expected to go online as the first graphite processing plant of its kind in the U.S. The company has represented that it will use proprietary technology that is environmentally friendly and specifically will not use hydrofluoric acid in the processing. AGP is to receive fresh water from Alexander City and, after pre-processing the waste at the plant, return a stream of wastewater to the Alexander City Sugar Creek municipal wastewater treatment plant. The Sugar Creek plant effluent discharges into Lake Martin.

Lake Watch was delighted that ADEM Director Lance LeFleur provided representatives from Lake Watch and from Lake Martin Homeowners and Boat Owners Association a meeting at ADEM with himself and six ADEM program managers to discuss the AGP permit. This very thorough and informative meeting lasted two hours. We learned that the AGP construction has not yet reached its final stage. No effluent is being discharged as yet.

The SID permit provides that the AGP plant must submit an updated comprehensive analysis of the plant’s actual wastewater within six months from initiation of discharge. Currently, there are no specific EPA federal effluent guidelines governing this categorical discharge. Until now, the industry hasn’t existed in the U.S. ADEM uses best professional judgement, evaluations of the municipal wastewater treatment plant and water quality standards in developing the permit. ADEM will review the permit to AGP after commencement of discharge. The Alexander City Sugar Creek WWTP also has a final say on the volume and composition of the wastewater that will be accepted into the plant. The ADEM permit issued to Alabama Graphite is subject to review by the EPA.

The permitted discharge volume is 400,000 gallons per day. The Sugar Creek WWTP has 8.5 million gallons per day capacity. Regarding the character of the discharge, we learned that the most significant regulated pollutant is expected to be a concentration of dissolved salts. Dissolved salts are mostly from calcium, magnesium and sulphur. It is represented that these salts are common components in soil and in seawater. ADEM stated that the volume of salts being added by the Alabama Graphite discharge is a small in relation to the design capacity of the WWTP.

ADEM said that heavy metals, if present in the graphite ore, precipitate out in the graphite purifica tion and pH adjustment processes. If metals are present in the waste, they will be at levels similar to those in domestic sewage, based on the data provided in the application. The SID permit estimates that the dis charge pH will be approximately 8.0. ADEM said the common range of allowable pH for the discharge for SID permits is 5.0 to 10.5. Regarding concern about “forever chemicals,” such as PFAS in the Alabama Graphite discharge, ADEM stated that there are no significant levels of forever chemicals expected in the discharge and that higher levels could likely be found in everyday residential wastewater.

ADEM said that they have no serious concerns about the pollutants listed in the Alabama Graphite wastewater as characterized in the Alabama Graphite permit application. The SID permit was developed to be protective of the receiving stream and protective of the municipal WWTP itself. ADEM is confident in the multiple layers of water quality protection for the lake, which include: n wastewater pretreatment at the plant by Alabama Graphite as required by the ADEM permit; n routine testing by AGP of their discharge as required by ADEM; n unannounced testing of the Alabama Graphite discharge by ADEM; n routine testing of discharge at the Sugar Creek WWTP; n review of discharge monitoring reports submitted monthly by Alabama Graphite and the Sugar Creek WWTP to ADEM.

Lake Watch has conferred with Alexander City’s Mayor “Woody” Baird, who said that, at this time, the City has no issues or concerns with the effluent expected to be produced by AGP. Baird said the AGP effluent post processing through the Sugar Creek WWTP is expected to be drinkable by the time it goes into the lake. It has been calculated that Lake Martin has about a 190-day retention time, meaning the water in the lake is renewed every 190 days, primarily by incoming flow from the Tallapoosa River and outgoing flow through Martin Dam. At this point, Lake Watch is rather confident that we may expect Lake Martin will not be adversely impacted by the Alabama Graphite discharge and that ADEM and Alexander City are on top of the current situation.
