Current through Vol. 41, No. 19, June 17, 2024

Section 252:619-3-2 - Total retention lagoons

(a)Erosion control. The permittee shall prevent erosion of the lagoon by:

(1) Maintaining a 1:3 slope on the inner and outer dikes of the lagoon, unless permitted otherwise;

(2) Using soil, gravel, concrete pads, shallow-root vegetation or other methods of erosion control as needed;

(3) Removing trees and deep-root vegetation from the dikes and bottom of the lagoon in a timely manner to maintain the integrity and stability of the lagoon;

(4) Protecting the inner dikes from wave action;

(5) Protecting the outer dikes from stormwater runoff and floodwaters;

(6) Protecting the dikes from burrowing animals; and

(7) Repairing any damage promptly.

(b)Freeboard. The permittee shall ensure that the lagoon has a minimum of three feet (3') of freeboard, unless otherwise specified in the permit.

(c)Seepage. The permittee shall, at all times, maintain the integrity of the liner or seal of the total retention lagoon to prevent seepage in excess of five hundred gallons per acre per day (500 gal/acre/day). No action shall take place during the use, maintenance, or operation of the lagoon that would destroy or diminish the effectiveness of any liner or seal, or increase the permeability of the liner or seal. Whenever seepage in excess of five hundred gallons per acre per day (500 gal/acre/day) from the lagoon is suspected or discovered, the permittee shall ensure that the discharge is reported to DEQ at (800) 522-0206 within 24-hours of the incident and that a completed and signed DEQ Form 619-001 "Self Reporting Wastewater Bypass Form" is submitted to DEQ within five (5) days of the incident.

(d)Influent lines. The permittee shall maintain influent lines to minimize short-circuiting by terminating influent lines at the center of the cell or a point at least one hundred feet (100') from the inside toe of any dike.

(e)Wastewater depth control structures. The permittee shall maintain control structures so that they properly control the wastewater depth in cells and route wastewater through the system.

(f)Piping. The permittee shall take steps to prevent turtles from clogging lagoon piping.

(g)Flow measurement. The permittee shall maintain flow measurement devices in proper working order.

(h)Treatment. The permittee shall operate and maintain the lagoon to produce optimum treatment results.

(i)Fencing. The permittee shall prevent unauthorized access to the lagoon by maintaining a fence around the lagoon. The fence may not interfere with the wind action to the lagoon's surface or shade the lagoon. Fences must have a lockable gate and must not obstruct maintenance vehicles or equipment. When the lagoon is located within three hundred fifty feet (350') of existing or platted residential or recreational areas, the permittee shall ensure that the lagoon is surrounded by a 6-foot high woven wire fence or equivalent.

(j)Signs. The permittee shall maintain a sign near or on the fence on each side of the lagoon site that designates the nature of the facility and advises against trespassing, the name of the owner and a contact phone number.

(k)Wind action. The permittee shall prevent any obstructions to wind action of the lagoon by:

(1) removing trees, weeds, cattails, and all other obstructions whenever they appear on or around the dikes or in the lagoon itself; and

(2) mowing the grass around the lagoons and on the dikes frequently enough to prevent the development of any obstructions to wind action.

(l)Access road. The permittee must maintain the access road to the lagoon so that it is passable during all weather conditions.

(m)Other maintenance requirements. The permittee shall maintain all structures of the lagoon in proper working order.

(n)Septic conditions prohibited. The permittee shall operate and maintain the total retention lagoon so that it does not become septic. If a lagoon becomes septic, the permittee shall take immediate steps to correct the condition without violating DEQ rules.

(o)Vector control. The permittee shall control vectors. In particular, mosquitoes and flies shall be controlled by:

(1) Maintaining an adequate lagoon depth;

(2) Preventing obstructions to wind action; and

(3) Taking steps to correct septic conditions.

(p)Surfactants. The use of surfactants or other chemicals or additives that would increase the seepage rate through a lagoon bottom is specifically prohibited.
