(b) Owned or operated by a municipality other than those described in paragraph (4)(a), of this rule, and that are designated by the Department as part of the large municipal separate storm sewer system due to the interrelationship between the discharges of the designated storm sewer and the discharges from municipal separate storm sewers described under paragraph (4)(a), of this rule. In making this determination the Department shall consider the following factors:

1. Physical interconnections between the municipal separate storm sewers,

2. The location of discharges from the designated municipal separate storm sewer relative to discharges from municipal separate storm sewers described in paragraph (4)(a), of this rule,

3. The quantity and nature of pollutants discharged to waters of the state; and,

4. The nature of the receiving waters.

(5) Major municipal separate storm sewer outfall means a municipal separate storm sewer outfall that discharges from a single pipe with an inside diameter of 36 inches or more or its equivalent (discharge from a single conveyance other than circular pipe which is associated with a drainage area of more than 50 acres); or for municipal separate storm sewers that receive stormwater from lands zoned for industrial activity (based on comprehensive zoning plans or the equivalent), an outfall that discharges from a single pipe with an inside diameter of 12 inches or more or from its equivalent (discharge from other than a circular pipe associated with a drainage area of 2 acres or more).

(6) Major outfall means a major municipal separate storm sewer outfall.

(7) Medium municipal separate storm sewer system means all municipal separate storm sewers that are either:

(a) Located in an incorporated place or county with a population of 100, 000 or more but less than 250, 000, as determined by the 1990 Decennial Census conducted by the federal Bureau of Census, or

In making this determination the Department shall consider the following factors:

1. Physical interconnections between the municipal separate storm sewers,

2. The location of discharges from the designated municipal separate storm sewer relative to discharges from municipal separate storm sewers described in paragraph (7)(a), of this rule,

3. The quantity and nature of pollutants discharged to waters of the state; and,

4. The nature of the receiving waters.

Point source is defined as any discernible, confined, and discrete conveyance, such as any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, or landfill leachate collection system from which pollutants are or may be discharged.

(10) Phase I MS4 means a municipal separate storm sewer system identified under Section 402(p)(2) of the Clean Water Act and subject to regulation under Section 402(p)(3)(B) of the Clean Water Act as implemented as part of the Department's federally approved National Pollutant Discharge Elimination System (NPDES) stormwater program pursuant to Section 403.0885, F.S., and this chapter.

(11) Phase II MS4 means a municipal separate storm sewer system subject to regulation under Section 402(p)(6) of the Clean Water Act, as implemented as part of the Department's federally approved National Pollutant Discharge Elimination System (NPDES) stormwater program pursuant to Section 403.0885, F.S., this chapter, and paragraph 62-621.300(7)(a), F.A.C., which incorporates by reference the Department's Generic Permit for Discharge of Stormwater from Phase II Municipal Separate Storm Sewer Systems, and includes MS4 facilities owned or operated by the United States and MS4 facilities operated by the Florida Department of Transportation (FDOT) that are not covered by an existing Phase I MS4 permit.
