treatment systems - Planning residential development sewage

treatment - Plats.

A. No small public sewage treatment system or individual sewage

treatment system shall be constructed or operated unless such

system, when constructed, complies with requirements prescribed by

the Environmental Quality Board as determined by an inspection

performed by the Department of Environmental Quality or a person

authorized by the Department.

1. It shall be the duty of the person contracting with an

installer who is modifying or installing an on-site sewage treatment

system for a residence or business to certify the number of bedrooms

in the residence or the water usage of the business that will be

served by the sewage treatment system so that the system can be

properly sized.

2. Upon reinspection of an approved system, performed at the

request of the lot owner, the Department or a person authorized by

the Department shall not require that the system be uncovered unless

there is evidence that the system has not functioned properly.

B. Any person, corporation or other legal entity which creates

or intends to create a residential development outside the corporate

limits of a city or town shall file a plat describing the methods of

sewage treatment for such residential development with the

Department. Approval of the plat shall be obtained prior to

recording the plat, offering a lot or lots for sale or beginning

construction within such residential development.

1. The plat shall include:

a. a description of the methods for providing water

supply and sewage treatment. If a public water supply

or public sewage is to be used, then verification of

the preliminary approval from the Department shall be

submitted along with the plat,

b. the actual lot size of each lot in square feet, acres

or fractions of acres, and

c. the location of any public water supply source,

including wells and surface water supplies, within

three hundred (300) feet of the residential

development.

2. Upon approval by the Department, the plat of the residential

development shall be imprinted with the stamp of the Department

bearing the word "approved", restrictions, if any, signature of the

Department or the Department's local representative and the date.

Approval of the plat shall be made effective thirty (30) days after

the plat is filed with the Department unless specifically rejected

prior to the expiration of the said thirty-day period of time.

3. The office of county clerk shall not record a plat

containing any lot of less than two and one-half (2 1/2) acres

situated outside the corporate limits of a municipality unless said

instrument bears the "approved" stamp of the Department. The

Department shall have no authority to disapprove and shall approve

plats of tracts that are being developed for individual residence in

which no single tract is less than two and one-half (2 1/2) acres,

provided that none of the lots are within three hundred (300) feet

of a public water supply source.

C. Persons creating or intending to create a residential

development, after receiving the stamp of approval from the

Department or the Department's local representative, shall file such

plat in the land records of the county where the residential

development is to be situated.

D. For purposes of this section, “subdivision of land for

purposes of a residential development” shall have the same meaning

as “subdivision” as defined in Section 863.9 of Title 19 of the

Oklahoma Statutes.

E. Any person who knowingly creates a residential development

without receiving the approval of the Department or the Department's

local representative of a plat or without filing of record a plat in

violation of this section, or who installs a private sewage

fined in Section 863.9 of Title 19 of the

Oklahoma Statutes.

E. Any person who knowingly creates a residential development

without receiving the approval of the Department or the Department's

local representative of a plat or without filing of record a plat in

violation of this section, or who installs a private sewage

treatment system on a lot for which disapproval of a private sewage

treatment system has previously been filed of record shall be deemed

guilty of a misdemeanor and upon conviction shall be punished by a

fine of not less than Five Hundred Dollars ($500.00) nor more than

Five Thousand Dollars ($5,000.00) for each violation.

F. The Department is authorized to use monies other than fees

or appropriated funds as such monies may be available to the

Department to offer financial assistance to indigent citizens of the

State of Oklahoma to reduce the incidence of surfacing sewage in the

State of Oklahoma.
