This study will collect nationwide
data on nutrient pollutant removal from publicly owned treatment
works (POTWs) with conventional secondary treatment. The data will
help set realistic and achievable nutrient reduction targets; help
POTW operators understand the range of opportunities to optimize
nutrient removals based on data from their peers; and encourage
improved nutrient removal performance at POTWs with less expense.
The full study is designed with multiple phases over the course of
four to five years. The first phase of the study is a screener
questionnaire, to collect basic information and characterize the
full population of POTWs. This information will help establish a
baseline of nutrient performance at the national level for all
POTWs.
In this renewal EPA proposes
three revisions to the currently approved screener questionnaire
ICR and supporting statement. First, EPA has reduced the maximum
number of respondents from 16,500 to 15,000 reflecting survey
responses already received as of October 30, 2020. Second, EPA has
made minor clarifying edits to the survey questions such as
providing additional examples of certain technology
classifications. Third, EPA is revising the respondent burden
estimates. The original average burden estimate assumed it would
take one hour to complete the registration process and three hours
to complete the full questionnaire. EPA reviewed start and end
times associated with questionnaires submitted online and found
that the average time to complete the long version of the online
questionnaire was 1.1 hours and the time to complete the short
version was 26 minutes. EPA revised the average burden to 2.25
hours for the questionnaire and 15 minutes for registration
(Questionnaire Section A) based on this information.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
