National Ammonia Water Quality Criteria Survey

This survey is part of an Ohio Water Development Authority (OWDA) Research and Development Grant (#7179) sponsored by the City of Johnstown, OH and supported by Ohio EPA, OWEA, and several partnering POTWs.

The data generated under this project is intended to be used to gain a better understanding of the magnitude of impacts on activated sludge and other plants, including the ability of and cost for these and other types of systems to comply. The ability of systems to comply with new ammonia criteria and new nutrient criteria in Ohio through optimization of operations, or via alternative means such as upgrades to the existing treatment trains, is being quantitatively and qualitatively addressed in this project.

The response to the survey, together with the experimental field data currently being gathered, helps to address to key questions prior to new rulemaking in Ohio:

1) Can activated sludge and other types of treatment plants consistently meet US EPA’s new ammonia criteria?
2) At what cost?

This survey should take approximately 30 minutes to complete.

1) Does your facility have NH3 limits?
Yes
No
2) What are your NH3 limits?
Summer
Winter
3) Do you consistently meet the ammonia limits? (no violations reported in last year):
Yes
No
4) Is your plant designed to remove ammonia?
Yes
No
5) What is your lowest achievable final effluent ammonia concentration under current operating conditions? (in mg/L total ammonia nitrogen)
6) If your plant employs Secondary Treatment, what is the technology type?
Select all that apply
Aerated Lagoon
Conventional activated sludge
Trickling filter
Oxidation ditch
Extended Aeration Package plant
Sequencing batch reactor
Biological Nutrient Removal
Enhanced BNR

Other (Please List Below)
If selected "Other" above, please list here
7) What is your design flow? (in mgd)
8) What is your average daily flow? (in mgd)
9) Does your effluent contribute significantly (e.g., >50%) to downstream flow?
Choose 1
10) What is the typical pH value of your upstream receiving water? (in standard units)
If you do not know the typical pH value of your upstream receiving water please mark "Uncertain"
Choose 1
11) Do you know if freshwater mussels exist in your receiving stream?
Choose 1
12) Are there operational challenges to achieve the limits? (efforts needed to maintain compliance, may or may not have occasional violations)
Choose 1
What are they?

13) Could you meet new NH3 limits if they were reduced by the following:
25 to 50%
Choose 1
50 to 75%
Choose 1
14) Indicate which changes are expected in order to meet new NH3 limits if they were reduced:
25 to 50%
Select all that apply
Infrastructure or New Equipment or Other Capital Costs
Personnel Costs
Other Operational Costs
Sludge Handling
50 to 75%
Select all that apply
Infrastructure or New Equipment or Other Capital Costs
Personnel Costs
Other Operational Costs

15) What is the facility’s annual operating cost?
16) When was the last facility upgrade? (Month/Year)
What was it?
17) How much did the facility upgrade cost?
18) What is the average rate for service?
19) Do you foresee a need to increase rates if new/ more stringent NH3 limits are imposed?
Yes
No
20) Do you have a pretreatment program?
Yes
No
21) Check the types of industrial operations in the system
