Gulf Power Company – Lansing Smith Power Plant, 2300 Bay County Road, Southport, Bay County, 

Florida, 32409. NPDES# FL0002267. Effluent composite samples for bioassay and grab samples for 

chemical and biological analyses for this facility were collected on February 21, 2011. Additional 

composite samples for bioassays were collected on February 23 and 25, 2011. 

Introduction 

Gulf Power Company – Lansing Smith Power Plant is a fossil–fuel electric power generation plant which 

discharges cooling water and overflow from an ash pond. (See Appendix F for detailed facility information 

provided by Kim Allen and Nathan Mulkey of FDEP Northwest District.) 

Methods 

Samples were collected from the EFF-2 NPDES sampling point for Outfall D-001 for bioassays and 

chemical analyses. Additional samples for chemical analyses were collected from the EFF- 4 NPDES 

sampling point for Internal Outfall I-01C and the Intake Cooling Water sampling point by Rick Abad, 

Corinna Clanton, and Nathan Mulkey (FDEP Northwest District) following DEP-SOP-001/01 FS 2400 

Wastewater Sampling. All DEP SOPs are available on the web at: 

http://www.floridadep.org/labs/bars/sas/sop/index.htm. 

See Appendix A for the completed chain of custody form. 

The 7-day chronic screening toxicity tests and algal growth potential test were performed following 

internal DEP SOPs TA07_015, TA07_09, and TA08_01 through TA08_09. All internal DEP SOPs are 

available on the web at: http://www.floridadep.org/labs/cgi-bin/sop/biosop.asp. 

Results and Discussion 

 Toxicity Test Results 

Tests were performed February 22 – March 1, 2011. 

Americamysis bahia 7 - day chronic screening bioassay – NOEC (survival): 100% 

 NOEC (growth): > 100% 

 IC25 (growth): > 100% 

Menidia beryllina 7 - day chronic screening bioassay – NOEC (survival): 100% 

 NOEC (growth): > 100% 

 IC25 (growth): > 100% 

The bioassay samples were not chronically toxic to the test organisms. 

See Appendix B for bioassay bench sheets. See Appendix C* for results of the last 20 standard 

reference toxicant (SRT) tests and the bench sheets and statistical analyses of the SRT tests that 

correspond to these facility tests. See Appendix D for test organism receipts. 

*The concurrent Americamysis bahia SRT was invalidated due to not meeting the minimum required mean organism 

dried wt for the control (0.2 mg dry wt/organism required; SRT control dry wt/organism was 0.197 mg). The follow-up 

SRT was initiated on March 15, 2011. 

 Algal Growth Potential 

The effluent Algal Growth Potential (AGP) was 3.0 AU (A - Value reported is the mean of two or more 

determinations, U - Material was analyzed for but not detected; the value reported is the minimum 

detection limit) mg dry wt/L of the saltwater species Dunaliella tertiolecta. Raschke and Schultz 

determined that AGP values above 10.0 mg dry weight/L represent a “problem” threshold for marine 

receiving waters, implying nutrient enrichment (personal communication, Marshall Faircloth, et. al. 

FDEP, with Ron Raschke USEPA Region 4 1987). The ratio (4.4:1) of inorganic nitrogen to 
3 

orthophosphate suggests that the effluent is nitrogen–limited; whereas, the ratio (15.6:1) of total 

nitrogen to total phosphorus suggests that the effluent is co-limited by both nitrogen and phosphorus. 

To determine actual nutrient limitation, a limiting-nutrient algal growth potential test should be 

performed (Maloney et al. 1978). 

See Table 1 for AGP results. 

 Chemistry Results for Surface Waters (D-001) 

Total residual chlorine and total ammonia were not detected in the bioassay sample in the laboratory. 

The total ammonia concentration in the grab sample collected and preserved for chemical analysis was 

0.01 U mg N/L. Due to the non-detection of ammonia; unionized ammonia could not be calculated. 

Total suspended solids (TSS) were detected in the D-001 effluent sample. Aluminum, arsenic, iron, and 

carbonaceous biochemical oxygen demand (CBOD) were detected between the laboratory method 

detection limits (MDL) and practical quantitation limits (PQL). Fecal Coliforms (3060 BJ CFU/100 ml) 

exceeded the Class II criteria for marine water (62-302.500 (6), F.A.C.). 

See Table 2 for results of analytes detected in the D-001 effluent and corresponding limits. 

 Chemistry Results for Ash Pond (I-01C) 

The total ammonia concentration in the grab sample collected and preserved for chemical analysis from 

the ash pond was 0.03 mg N/L. Based on the pH, salinity, and temperature of the effluent as collected, 

the calculated unionized ammonia concentration was ≤ 0.02 mg/L. 

Arsenic, cadmium, chromium – III, iron, nickel, selenium, and radium 226 were detected in the effluent 

at levels that comply with Class II marine water quality criteria (62-302.530, F.A.C.), or permit 

conditions (NPDES# FL0002267). Copper and TSS were detected between the laboratory MDL and 

PQL. Radium 226 was also detected in the field blank. 

See Table 3 for results of analytes detected in the I-01C effluent and corresponding limits. 

 Chemistry Results for Intake Cooling Water 

Iron was detected in the effluent at levels that comply with Class II marine water quality criteria (62-

302.530, F.A.C.) Nickel was detected between the laboratory MDL and PQL. 

See Table 3 for results of analytes detected in the intake cooling water and corresponding limits. See 

Appendix E for a complete list of chemical analyses performed. See Appendix B for bioassay lab 

equipment. 

Conclusion 

The effluent sample collected from the EFF-2 NPDES sampling point for Outfall D-001 for this facility on 

February 21, 23, and 25, 2011, was not chronically toxic to either test species during the 7-day chronic 

screening bioassays. The effluent AGP result was less than the "problem” threshold for marine receiving 

waters. Effluent water quality samples collected on February 21, 2011, exceeded applicable water quality 

standards for fecal coliforms. 

Samples from the ash pond (I-01C) and intake cooling water did not exceed any applicable water quality 

standards or permit limits.
