nonroad equipment manufacturers are 

allowed to delay compliance with Tier 

4 standards for up to seven years as long 

as they comply with certain limitations. 

The program seeks to ease the impact of 

new emission standards on equipment 

manufacturers. This is achieved by 

allowing additional time for equipment 

manufacturers to redesign their 

products as needed in response to 

changes in engine designs. Participation 

in the program is voluntary. 

Participating equipment manufacturers 

and the engine manufacturers who 

provide TPEM engines are required to 

keep records and submit annual reports. 

The information requested is 

collected by the Diesel Engine 

Compliance Center (DECC), Compliance 

Division (CD), Office of Transportation 

and Air Quality, Office of Air and 

Radiation, EPA. DECC uses this 

information to ensure that 

manufacturers are in compliance with 

applicable regulations and the CAA. 

The information may also be used by 

EPA’s Office of Enforcement and 

Compliance Assurance and the 

Department of Justice for enforcement 

purposes. Most of the information is 

collected in electronic format and stored 

in CD’s databases. 

Manufacturers are allowed to assert a 

claim of confidentiality over 

information provided to EPA. 

Confidentiality is granted in accordance 

with the Freedom of Information Act 

and EPA regulations at 40 CFR Part 2. 

Non-confidential information may be 

disclosed on OTAQ’s Web site or upon 

request under the Freedom of 

Information Act to trade associations, 

environmental groups, and the public.

Respondents/affected entities: Entities 

potentially affected by this action are 

manufacturers of nonroad compression 

ignition (CI) engines, marine CI engines 

and on-highway heavy-duty engines; 

owners of heavy-duty truck fleets, and 

manufacturers of nonroad compression 

ignition equipment. 

Respondent’s obligation to respond: 

Engine manufacturers must respond to 

this collection if they wish to sell their 

products in the U.S., as prescribed by 

Section 206(a) of the CAA (42 U.S.C. 

7521). Participation in ABT is 

voluntary, but once a manufacturer has 

elected to participate, it must submit the 

required information. Likewise, 

participation in TPEM is voluntary, but 

once an engine or equipment 

manufacturer chooses to participate, it 

must submit the required notifications 

and annual reports (40 CFR 1039.625 

and 1039.626). If applicable to a 

particular engine family, compliance 

programs reporting is mandatory. 

Estimated number of respondents: 

2,350 (total). 

Frequency of response: Annual, 

quarterly, on occasion. 

Total estimated burden: 244,287 

hours (per year). Burden is defined at 5 

CFR 1320.03(b). 

Total estimated cost: $34,470,029 (per 

year), includes $13,752,082 annualized 

capital or operation & maintenance 

costs. 

Changes in Estimates: There is an 

increase of 70,101 hours in the total 

estimated respondent burden compared 

with the ICR currently approved by 

OMB. This increase is due to (1) the 

merger of ICRs 1684.18 and 1826.05, 

and (2) an increase in the number of 

respondents. Please note that these are 

preliminary estimates. EPA is still 

evaluating information that could lead 

to a change, likely an increase, in these 

estimates.

Stakeholder Input; Experts Forum on 

Public Health Impacts of Blending at 

Publicly Owned Treatment Plants 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: The Environmental Protection 

Agency is announcing plans to hold a 

forum of public health experts in June 

2014 to discuss the public health 

implications of discharges of ‘blended’ 

effluent from publicly owned treatment 

works (POTWs) served by separate 

sanitary sewers into waterways. The 

discussion will include public health 

implications of such discharges. 

Today’s notice asks for 

recommendations of public health 

experts who would be interested and 

qualified to participate in the forum. In 

addition, today’s notice seeks 

recommendations of wastewater 

treatment plant design and operation 

experts to serve as advisors to the public 

health forum participants. Today’s 

notice also provides the public with an 

opportunity to submit data regarding the 

performance of municipal wastewater 

treatment plants during wet weather 

conditions. 

Blending is a practice used by some 

POTWs to manage wastewater when 

flows to the plant exceed the capacity of 

the secondary treatment units, which 

happens most often during wet weather 

conditions. POTWs engaged in the 

practice of blending divert excess flow 

around secondary treatment units and 

subsequently blend the diverted flows 

to the portion of flow that received 

secondary treatment. In some cases the 

diverted flows receive some additional 

treatment before blending. The Agency 

is interested in evaluating the public 

health implications of different blending 

scenarios, including scenarios where the 

diverted flow is subject to supplemental 

physical/chemical treatment prior to 

blending and where the diverted flows 

do not receive any additional treatment 

prior to blending. 

The Agency is undertaking this 

outreach to help advance the Clean 

Water Act (CWA) objective to restore 

and maintain the chemical, physical 

and biological integrity of the nation’s 

waters (CWA, Section 101(a)). 

DATES: Suggestions on experts should be 

made on or before May 4, 2014. Other 

technical information requested in this 

notice should be provided on or before 

May 19, 2014. We expect to hold the 

public health forum during June of 

2014. 

ADDRESSES: Submit your 

recommendations for experts or other 

input by one of the following methods: 

• Email to weiss.kevin@epa.gov. 

• Mail: Kevin Weiss, Water Permits 

Division, U.S. Environmental Protection 

Agency, Room 7421J EPA East, 1200 

Pennsylvania Avenue NW., Washington, 

DC 20460. 

FOR FURTHER INFORMATION CONTACT: EPA 

will post the date and location of the 

public health experts’ forum at:

SUPPLEMENTARY INFORMATION: 

I. Background 

Wastewater collection systems collect 

wastewater from homes and other 

buildings and convey it to wastewater 

treatment plants for proper treatment 

and disposal. The collection and proper 

treatment of municipal wastewater is 

vital to the public health in our cities 

and towns and to the viability of our 

receiving waters. 

During and immediately after wet 

weather events, flows to wastewater 

collection systems and to treatment 

facilities typically increase. Significant 

flow increases in a wastewater 

collection system can cause overflows of 

untreated wastewater and sewage 

backups into buildings. For some 

municipalities, an important component 

of their strategy to reduce collection 

system overflows and backups into 

buildings is to increase the conveyance 

of wet weather flows to a treatment 

plant. Significant increases in flow at 

the treatment facility can cause 

operational challenges, especially for 

biological-based secondary treatment 

units. Activated sludge systems are 

particularly vulnerable to high volume 

peak flows. Peak flows that approach or 

exceed design capacity of an activated 

sludge unit can shift the solids 

inventory from the aeration basin to the 

clarifier(s), and can result in excessive 

solids losses from the clarifier(s). If a 

clarifier experiences excessive loss of 

solids, treatment efficiencies can be 

lowered for weeks or months until the 

biological mass in the aeration basins is 

reestablished. In addition to these 

hydraulic concerns, wastewater 

associated with peak flows may have 

low concentrations of oxygendemanding pollutants, which can also 

decrease treatment efficiencies. 

Biological nutrient removal processes 

typically have an increased sensitivity 

to the hydraulic and loading 

fluctuations associated with wet 

weather flows. 

Design and operational options that 

are routinely employed to maintain the 

effective capacity of biological-based 

secondary treatment units include: 

• Providing alternative feed patterns 

in the aeration basin(s); 

• Increasing the returned activated 

sludge rate relative to those needed for 

steady flow;
