Case #/Title:
ES-2025-05/Wastewater Treatment Plants
Supervisor Districts:
All Districts
Applicant:
Maricopa County Environmental Services Department (Department)
Request:
Approve proposed revision to Maricopa County Environmental
Health Code (MCEHC), Chapter I & II.
Support/Opposition:
The Department held a hybrid stakeholder public meeting on
December 16, 2025, and a virtual meeting on February 26, 2026.
Twenty stakeholders attended the meetings.
Comments received during the stakeholder meeting were supportive;
there were no comments in opposition. A letter was received in
support of the case.
Department
Recommendation:
The Department recommends that the Board of Supervisors (BOS)
approve the proposed MCEHC revision.
BOH
Recommendation:
The Board of Health (BOH) voted unanimously to approve the
Department’s proposed revision and proceed according to the EROP
standard process.
Executive Summary:
Inspection and regulation of wastewater treatment plants are not
delegated to the Department by the Arizona Department of
Environmental Quality (ADEQ). Currently, the Department conducts
regulatory activities related to wastewater treatment plants under the
authority of the MCEHC. ADEQ also regulates wastewater treatment
plants in Maricopa County, requiring an Aquifer Protection Permit, and
believes the Department’s program overlaps. The Department
proposes eliminating the need for permits and routine inspections for
Page 2 of 2
wastewater treatment plants to avoid duplicative oversight with
ADEQ.
This proposal follows the EROP policy and workflow process; fee
changes are requested.
In accordance with the Maricopa County Resolution, “Moratorium on
Increased Regulatory Burdens,” the County Manager authorized the
Department to proceed with this case in September 2025. Also, the
Board of Supervisors was briefed in September 2025.
The Department conducted a stakeholder workshop on December 16,
2025, and February 26, 2026. On April 27, 2026, the Department
presented a Staff Report for this case to the Board of Health (BOH), at
which time the BOH approved this case to proceed on the EROP
standard process for the BOS to adopt this proposed Department
revision.

Department
Recommendation:
The Department recommends that the Board of Health approve the
Department to move forward with the proposed changes to the Wastewater
Treatment section of the MCEHC through the EROP Standard Process, to
make recommendations to the Board of Supervisors (BOS).

Inspection and regulation of wastewater treatment plants are not delegated
to the Department by the Arizona Department of Environmental Quality
(ADEQ). Currently, the Department conducts regulatory activities related to
wastewater treatment plants under the authority of the MCEHC. ADEQ also
regulates wastewater treatment plants in Maricopa County, requiring an

To:

Darcy Kober, Assistant County Manager
From: Andy Linton, Director
Subject: County Manager Approval- Enhanced Regulatory Outreach Process (EROP) Case ES-2025-
005/Wastewater Treatment Plants
In accordance with the Maricopa County Resolution, "Moratorium on Increased Regulatory Burdens,"
the Environmental Services Department is seeking your approval to proceed with EROP ES-2025-
005/Wastewater Treatment Plants. This proposal qualifies for County Manager approval under the
moratorium, as it removes non-mandated regulatory oversight and duplicative activities related to
wastewater treatment plants.
Currently, inspection and regulation of wastewater treatment plants are not delegated to the Maricopa
County Environmental Services Department (Department) by the Arizona Department of Environmental
Quality (ADEQ). Despite this, the Department currently regulates wastewater treatment plants under
the authority of the Maricopa County Environmental Health Code (MCEHC). Because ADEQ also
regulates wastewater treatment plants in Maricopa County—requiring an Aquifer Protection Permit—
the Department’s activities overlap with ADEQ’s regulatory program.
To eliminate duplicative oversight, the Department proposes discontinuing construction approvals and
routine inspections for wastewater treatment plants. This action aligns with the EROP policy and
workflow process and does not include any fee changes.
The Department believes these changes are both prudent and necessary to ensure that only mandated
functions are performed while continuing to uphold the highest standards of public and environmental
health protection. Accordingly, we respectfully request your approval to advance this proposal in
accordance with the Maricopa County Resolution on the Moratorium on Increased Regulatory Burdens.
Approved by Jennifer Pokorski, County Manager

sponsoring school district must demonstrate to the Board of Health that

b.
Investigation Fees:
If any work for which a permit is required has been commenced without first
obtaining said permit, a special investigation shall be made before a permit may
be issued for such work. An investigation fee, in addition to the permit fee, shall
be collected whether or not a permit is then or subsequently issued. The fee shall
be calculated at a rate of $130.00 per hour. The payment of such investigation
fee shall not exempt any person from compliance with all other provisions of the
Environmental Health Code or the regulations of the Arizona Department of
Health Services or Arizona Department of Environmental Quality or from any
penalty prescribed by law.
c.
Plan Review Fees:
Plan review fees shall be determined based on a flat fee or an initial fee plus an hourly
rate.
(1)
Where it applies, if the actual cost of processing the application for a plan
review is greater than the initial fee, the Department shall send the Applicant
a final itemized bill for the difference between the initial fee and the actual
cost of processing the application except that the final bill shall not exceed the

Plan Review Options: (requires approval prior to project submittal)
Expedited Plan Review – For plan review of a project that requires expediting.
Phased Plan Review – For plan review of a project where the design is executed in phases and requires multiple approvals to be issued.
Design/Build Plan Review –– For plan review of a project that is executed using a design/build methodology.
An applicant may elect to have the project reviewed as an expedited and/or, if applicable, a phased or design/build plan review.
Selecting an expedited, phased or design/build plan review option doubles the flat, initial and maximum fee amounts and the plan
review hourly billing rate. Selecting an expedited plan review option in combination with a phased or design/build plan review option
quadruples the flat, initial and maximum fee amounts.
The amount due when a project is initially submitted for review and approval is based on the fee item(s) flat/initial fee amount, the fee
item quantities specified and the selected expedited, phased or design/build plan review options. For projects that include fee items
with initial/maximum fees (i.e. billable projects), the maximum amount that may be charged for the project is based on the fee item(s)
maximum fee amount, the fee item quantities specified and the selected expedited, phased or design/build plan review options.

REGULATION 7.
Suspension and Revocation of Permits
a.
Suspension of Permit:
(1)
When the Department determines that a permit holder has failed to comply
with this Environmental Health Code or that there exists on the permitted
premises an imminent health hazard, the Department may summarily and
immediately suspend the permit without prior notice to the permit holder.
Notice of the Suspension shall be served on the permit holder by personal
delivery or mailed by certified or registered mail, postage prepaid and return
receipt requested, to the permit holder’s last known address.
(2)
Within fifteen days of being served with the Notice of Suspension, the
permit holder may file a motion to vacate the suspension order with the
Department and the Environmental Health Officer shall hear such motion
within five (5) days. An order of summary suspension shall remain in
effect for no more than 25 days. If the violation is not corrected within
the 25 days, the Department may issue another suspension order.
(3)
Upon suspension of the permit, the Department may close the permit
holder’s establishment, premises or vehicle and the Department’s red closed
sign shall be posted on the establishment, premises or vehicle and shall be
clearly visible to the public. The premises shall remain closed and the sign

or vacated by the Department or the permit is revoked. The permit holder
shall maintain the sign in an unobstructed manner in the location where the
sign was posted.
b.
Revocation of Permit:
(1)
The Department may revoke a permit for two or more violations of this
Environmental Health Code, for any violation that threatens the health or

establishment, premises, or vehicle, or the enforcement of this
Environmental Health Code.
(2)
The Department shall serve written Notice on the permit holder or the
person in charge stating the specific reason(s) for revoking the permit and

R 9-25-2013
Department within the twenty (20) day notice period. If a request for a
hearing is timely filed, the Environmental Health Officer or an independent
Hearing Officer appointed by the Department shall hold a hearing as soon
as practicable. After the hearing, the Environmental Health Officer shall
revoke the Notice of Revocation and reinstate the permit, or revoke or
modify the permit.
(3)
Application for a new permit after revocation.
(a)
After a permit is revoked, the former permit holder may submit a

establishment, premises or vehicle is closed. The red closed sign shall be
posted on the establishment, premises, or vehicle and shall be clearly visible
to the public. The premises shall remain closed and the sign shall remain

concealed, damaged, or otherwise removed without the Department’s
prior written authorization.
REGULATION 8.

When a Notice is served on the permit holder, the Department may post the
Department’s yellow public Notice sign at the permit holder’s establishment,
premises or vehicle notifying the public that the establishment, premises or vehicle
may not meet Maricopa County health standards or the permit holder failed to pay
a fee required under this Environmental Health Code. If posted, the yellow public
Notice sign shall be posted on the establishment, premises, or vehicle and shall be

corrected, the fee is paid, the Notice is revoked after a hearing, or removal is
authorized by the Department.
c.

A statement of the time, place and nature of the hearing.
(b)
A statement of the legal authority and jurisdiction under which the
hearing is to be held.
(c)
A reference to the particular sections of the statutes and regulations
involved.
(d)
A short, plain statement of the matters asserted. If the Department
is unable to state the matters in detail at the time the Notice is served,
then the Notice may be limited to a statement of the issues involved.
If the permit holder requests a more definite statement, the
Department shall, if it is able, provide a more definite and detailed
statement to the permit holder prior to the hearing.
REGULATION 10. Severability
Should any section, sentence, clause, phrase, or word of this Environmental Health Code be
declared unconstitutional or invalid by a court of competent jurisdiction, the remainder of said Code
shall not be affected thereby.
REGULATION 11. Violation
a.
Violations of this Environmental Health Code may be redressed by proceedings
pursuant to A.R.S. 36-601.B., 49-142 or 49-143; by injunctive relief in Superior
Court; or by any other applicable remedies provided by law. In addition, persons who
violate a provision of this Environmental Health Code are guilty of a Class 3
DRAFT
23
1-21
R 9-25-2013
Misdemeanor if the person holds a valid permit or a Class 2 Misdemeanor if the person
does not hold a valid permit under this article as provided in A.R.S. 36-183.03 and
36-191 and may be punished accordingly.
b.
For purposes of determining the number of days of violation for which a civil penalty
may be assessed under this Code, if the Environmental Officer has notified the source
of the violation and makes a Prima Facie showing that the conduct or events giving
rise to the violation are likely to have continued or recurred past the date of Notice,
the days of violations shall be presumed to include the date of such Notice and each
day thereafter until the violator establishes that continuous compliance has been
achieved, except to the extent that the violator can prove by a preponderance of the
evidence that there were intervening days during which no violation occurred or that
the violation was not continuing in nature.
c.
Notice under this section is accomplished by the issuance of a Cease and Desist
Order, Notice of Violation, Permit Revocation, or by filing a complaint in Superior
Court.
REGULATION 12. Cease and Desist; Abatement
When the Environmental Health Officer has reasonable cause to believe from information
furnished to such officer or from investigation made by such officer that any person is maintaining
a nuisance or engaging in any practice contrary to this code, he may forthwith serve upon such
person by certified mail, in person or by designee a Cease and Desist Order requiring the person,
upon receipt of the order to cease and desist from such act. The Department’s red closed sign may
be posted in a conspicuous place on the premises, clearly visible to the public, and will remain in
place until removal is authorized by the Environmental Health Officer. It is the responsibility of
the permit holder to maintain the sign in an unobstructed manner in the location where the sign
was placed by the Environmental Health Officer. Within fifteen days after receipt of the order,
the person to whom the order is directed may request a hearing. The Environmental Health Officer
or his designee, within a reasonable time thereafter, shall hold a hearing, to determine whether the
order is reasonable and just, and the practice engaged in is contrary to this code.
Upon the failure or refusal of a person to comply with the order of the Environmental Health
Officer or if a person to whom the order is directed does not request a hearing and fails or refuses
to comply with the Cease and Desist Order served under the provisions of this section, the
Environmental Health Officer or his designee may file an action in the Maricopa County Superior
Court restraining and enjoining the person from engaging in further acts. The court shall proceed
as in other actions for injunctions.
REGULATION 13. Posting of Notices
The Environmental Health Officer may, for the purpose of notification to the public, post a
warning sign at any premises or establishment describing the nature of legal action being taken against
said premises or establishment under the provisions of the Environmental Health Code.
DRAFT
24
1-22
R 9-25-2013
This sign will be posted in a conspicuous place on the premises, clearly visible to the public,
and will remain in place until removal is authorized by the Environmental Health Officer. It is the
responsibility of the permit holder and/or owner to maintain the sign in an unobstructed manner in the
original location where the sign was placed by the Environmental Health Officer.
REGULATION 14. Nuisance Abatement Assessment and Lien
a.
After the Department has completed the actions necessary to abate or remove a
nuisance, source of filth or cause of sickness from private property pursuant to
A.R.S. § 36-602(A), the Director may issue an Assessment Statement to the owner
of the property on which the nuisance, source of filth or cause of sickness was
located.
b.
The Assessment Statement shall include the following information:
(1)
A description of the assessed costs incurred by the Department, which may
include the actual costs of the abatement or removal action, incidental costs,
personnel costs, attorney’s fees and costs to obtain and execute an
inspection and Abatement Warrant under A.R.S. § 36-603, and the costs of
any additional inspections.
(2)
Notice that the property owner shall pay the assessed costs within thirty
days after service of the Assessment Statement, or by such other date as
may be specified for payment in the Assessment Statement, unless the
property owner requests an appeal pursuant to the subsection h. below.
(3)
Notice that the property owner may appeal the assessment to the Maricopa
County Board of Health in writing within thirty days after service of the
Assessment Statement.
(4)
Notice that failure to pay the Assessment Statement may result in a lien
being recorded against the property on which the nuisance, source of filth
or cause of sickness was located.
c.
If the property on which the nuisance, source of filth or cause of sickness was
located is not the property owner’s residence or is vacant or unoccupied, the
Assessment Statement shall be served on the property owner by personal delivery,
left at the property owner’s usual place of abode, served in a manner as provided
for service of process under the Arizona Rules of Civil Procedure, or mailed by
certified or registered mail, postage prepaid and return receipt requested, to the
owner’s last known address or to the address shown on the property owner’s
driver’s license.
d.
If the property on which the nuisance, source of filth or cause of sickness was
located is the property owner’s usual place of abode, the Assessment Statement
shall be served on the property owner by personal delivery, left at the property, or
served in a manner as provided for service of process under the Arizona Rules of
DRAFT
25
1-23
R 6-23-10
Civil Procedure, or mailed by certified or registered mail, postage prepaid and
return receipt requested, to the property.
e.
If the Assessment Statement is served by being left at the property or at the property
owner’s usual place of abode, it may be left in any manner reasonably calculated to
provide actual Notice to the property owner, including a door hanger, being taped to
the front door, being placed in a mail slot or mailbox, and being placed under a
doormat.
f.
Service of the Assessment Statement is effective and the time for the property
owner to file an appeal commences on the date it is delivered to the property owner,
left at the property or at the property owner’s usual place of abode, or mailed by
certified or registered mail as provided in subsections c. and d. above.
g.
On the date the Assessment Statement is served on the property owner, or as soon
thereafter as is practicable, the Department shall record a copy of the Assessment
Statement in the office of the Maricopa County Recorder as constructive notice to
all current and future lien holders of the property. The Assessment Statement shall
clearly state that it is being recorded as a Notice and not as a lien. All persons who
perfect a lien on the property and all persons who acquire title to the property after
the Assessment Statement is recorded shall be subject to the Department’s
assessment claim against the property.
h.
The property owner may appeal the Assessment Statement by filing a written
request for a hearing to the Maricopa County Board of Health within thirty days
after service of the Assessment Statement. A copy of the request for a hearing
shall be delivered or mailed by certified or registered mail, postage prepaid and
return receipt requested, to the Department. The request shall state the specific
grounds for the appeal.
(1)
After a hearing, the Board of Health may uphold, modify or revoke the
Assessment Statement and shall sign a written order of its decision. The
Department shall prepare a form of order for the Board of Health to sign.
(2)
If the Board of Health upholds or modifies the Assessment Statement, the
assessed costs shall be paid within thirty days of the Board of Health’s
decision, or by such other date as may be specified for payment by the Board
of Health.
i.
If the property owner fails to pay the assessed costs before the time for payment
expires, the Department may record a Notice and Claim of Assessment Lien against
the property on which the nuisance, source of filth, or cause of sickness was abated
or removed. The Notice and Claim of Assessment Lien, from the date it is
recorded in the Office of the Maricopa County Recorder, is a lien on the property
until it is paid in full. The Notice and Claim of Assessment Lien relates back
DRAFT
26
1-24
R 6-23-10
to and its priority is determined as of the date the Assessment Statement was
recorded on the property as a Notice as provided in subsection g. above.
j.
A Notice and Claim of Assessment Lien under this regulation is prior and superior
to all other liens, obligations, Deeds of Trust, and other encumbrances on the
property, except liens for general taxes and prior recorded mortgages.
k.
The Department may bring an action to enforce the Assessment Lien in the Superior
Court in the county in which the property is located at any time after the Assessment
Statement is recorded. The failure to enforce the Assessment Lien by bringing an
action does not affect the lien’s validity. The recorded assessment is Prima Facie
evidence of the truth of all matters recited in the Assessment Statement and of the
regularity of all proceedings before recording the Assessment Statement.
l.
A prior assessment is not a bar to a subsequent assessment or assessments for and
any number of Assessment Liens on the same property may be enforced in the same
action.
m.
A recorded Assessment Statement does not limit, restrict or otherwise affect the
authority of the Department to undertake any additional enforcement action that is
authorized by law, including applicable ordinances or regulations.

Background
•
The Environmental Services Department (ESD) regulates wastewater treatment plants under the
authority of the Maricopa County Environmental Health Code (MCEHC) by:
o
Engineering design review - Approvals to Construct (ATC) & Approvals of Construction (AOC)
o
Verifying conformance with MAG 208
o
Routine inspections of wastewater treatment facilities & monthly review of water quality report
•
Regulatory activities related to wastewater treatment plants are not delegated to Maricopa County.
•
Both ESD and the Arizona Department of Environmental Quality (ADEQ) regulate wastewater treatment
plants in Maricopa County. Much of the regulatory oversight is duplicative.
Wastewater Treatment Plants
3
Background
•
Maricopa County is the only county in Arizona that has its own wastewater treatment
plant engineering review program.
•
Customers are required to submit engineered plans to both ESD and ADEQ, and regular
operational inspections are conducted at the facilities by both departments.
•
The duplication of work adds additional time, cost, and complexity for customers.
•

MAG requests letters of “no objection,” “approval,” or “comment” from
jurisdictions within a 3-mile radius when a MAG 208 amendment is
proposed.
•
The MAG Regional Council considers these letters when voting on
MAG 208 amendments.
•
MCESD conducts engineering reviews for infrastructure used to convey
wastewater between service areas (service area expansions).
•
ADEQ delegated this responsibility to MCESD.
•
Regulations require MCESD to verify that this conveyance conforms
with MAG 208 prior to issuing Approvals to Construct.
6
Purpose of Proposed Code Change
• To avoid duplicative oversight, the Department proposes to discontinue
construction reviews/approvals and operational permits/inspections for
wastewater treatment plants.
• The Department will continue reviews/approvals for wastewater
infrastructure and water treatment plans, as currently delegated from ADEQ.
• ADEQ will continue review and approvals for wastewater treatment plants in
Maricopa County, including issuance of Aquifer Protection Permits (APP),
verification of conformance with MAG 208, and operational inspections.

Proposal
•
Maricopa County Environmental Services (ESD) proposes to remove regulations
related to wastewater treatment plants from the Maricopa County Environmental
Health Code (MCEHC).
•
By removing these requirements, engineering design reviews/approvals and
operational permits/inspections of wastewater treatment plants would no longer be
conducted by ESD.
Proposed Change
5
Background
• ESD regulates wastewater treatment plants by:
o Conducting engineering design reviews and issuing Approvals to Construct (ATC)
& Approvals of Construction (AOC).
o
Verifying conformance with MAG 208.
o Conducting routine operational inspections & monthly reviews of water quality
reports.

Background
•
Regulatory activities related to wastewater treatment plants are not delegated to
Maricopa County.
•
ESD regulates wastewater treatment plants under the authority of the Maricopa County
Environmental Health Code (MCEHC).
•
As a result, both ESD and the Arizona Department of Environmental Quality (ADEQ)
regulate wastewater treatment plants in Maricopa County. Much of the regulatory
oversight is duplicative.
Authority/Mandates
8
Background
•
Maricopa County is the only county in Arizona that has its own wastewater treatment
plant engineering review program.
•
Customers are required to submit engineered plans to both ESD and ADEQ, and regular
operational inspections are conducted at the facilities by both departments.
•
The duplication of work means additional time, cost, and complexity for customers.
•
ARS 11-1604 – “avoid duplication of other laws…and dual permitting to the maximum
extent practicable.”
Duplicative Regulatory Activities
9
Outcome
•
ESD would remove duplicative oversight by discontinuing engineering design reviews
and inspections of wastewater treatment plants.
o
ESD will continue reviews/approvals for wastewater infrastructure and
water treatment plants, as currently delegated from ADEQ.
o
ADEQ will continue reviews and approvals for wastewater treatment plants
in Maricopa County, including issuance of Aquifer Protection Permits
(APP), verification of conformance with MAG 208, and operational
inspections.

Stakeholder Workshop
Wastewater Treatment Plants
Date: December 16, 2025
Stakeholder Present: Amy Baker –City of Glendale, Megan Sheldon – City of Glendale, Karla Camou
Guerra – City of Glendale, Andrea Cooper – City of Phoenix, Hilary Hartline – City of Phoenix,
Christina Hoppes – City of Tempe, Juie Hoffman – Maricopa Association of Governments, Jen
Hetherington – City of Mesa, Alexis Camberos – Denali Water, Phil Garcia
Staff Present: Andy Linton – Director, Robert Stratman – Deputy Director, Sylvie Donaldson –
Administrator, Ryan Hall – Water & Waste Management Division Manager, Sujana Attaluri –
Water/Wastewater Treatment Program Manager, Logan Peiman – Business & Community Liaison
Presenter: Andy Linton
Minutes*: Andy Linton covered the Enhanced Regulatory Outreach Program (EROP) process and
how stakeholders can stay informed on this and other upcoming cases. He further explained that
Inspection and regulation of wastewater treatment plants are not delegated to the Maricopa County
Environmental Services Department (Department) by the Arizona Department of Environmental
Quality (ADEQ). Currently, the Department conducts regulatory activities related to wastewater
treatment plants under the authority of the MCEHC. ADEQ also regulates wastewater treatment
plants in Maricopa County, requiring an Aquifer Protection Permit, and believes the Department’s
program overlaps. The Department proposes eliminating the County requirement for construction
and operation permits for wastewater treatment plants to avoid duplicative oversight with ADEQ.
Karla Camou Guerra with City of Glendale asks, are lift stations considered under the collection
system?
Andy Linton says yes, this would continue to be regulated.
Megan Sheldon with the City of Glendale asks, if there is an existing wastewater project under
construction, what would be the process to finish the project with the County or transfer it to ADEQ?

Andy Linton says there would be no transfer to ADEQ, as it's already required by ADEQ. There would
be no additional downtime. It would end the process completely at Maricopa County.
Andrea Cooper with the City of Phoenix asks if the operating permit renewal would still be required?
Andy Linton says no; if approved in July 2026, then an operating permit would no longer be required.
Andrea Cooper asks if the monthly operating reports would be required?
Andy Linton says that as this is a part of the operational inspection review, it would no longer be
required.
Amy Baker with City of Glendale asks, in some places the water reclamation system terminology
has been stricken. What would the County’s role be related to reuse permits? The City of Glendale
receives a permit from the Arizona Department of Environmental Quality (ADEQ).
Ryan Hall states that, given the current wording of the cross-outs, the Department would still permit
reuse facilities. When discussing with ADEQ, it became apparent that there was overlap with these
permits. This is also a function not delegated to the Department. The Department can look into this
further.
Megan Sheldon says, this doesn’t include collection systems. Is there a plan to explore other
duplicative programs in the future?
Andy Linton says that collection systems are delegated to the Department by ADEQ, so ADEQ
should not perform any activities related to collection systems.
Meeting adjourned.

Andrea Cooper with City of Phoenix says she is supportive of removing the duplicative effort. MORs
are normally required to be submitted to the county. Will ADEQ require the MORs to be sent to them
instead?
Ryan Hall says, the MORs would no longer be required to be submitted to the Department if the case
is approved. ADEQ would not change their process or requirements if the Department’s case
passes.

Andrea Cooper asks if the City of Phoenix would start paying ADEQ for operating permits?
Ryan Hall says there would not be any changes to ADEQ. Sujana Attaluri adds that says yes, ADEQ
would still have an annual APP operational fee.
Andy Linton says this case has no bearing on any requirements ADEQ has. The Department has not
received word that they are changing any of their processes.
Amy Baker with the City of Glendale asks, Will Sewer lines, lift stations, and capacity assurance for
sewer lines be submitted to the Department?
Andy Linton says any sewer infrastructure, like lift stations, sewer mains, and capacity assurances
are delegated to the Department, and there will be no changes with these delegations.
Amy Baker asks, is this the same with reclaimed water lines design and construction?
Ryan Hall says, this will not change anything with the reclaimed conveyance lines, which will still
require a review from the Department.
Meeting adjourned.
