1.1 Purpose
These rules establish
requirements for implementation of R.I. Gen. Laws Chapter 46-19,
"Inspection of Dams and Reservoirs," and to provide for the
safety of dams to protect the public, real property and natural
resources by establishing reasonable standards and to create a public
record for reviewing the performance of dams.
1.2 Authority
These rules and regulations
are promulgated pursuant to the requirements and provisions of R.I.
Gen. Laws Chapters 42-17.1, “Department of Environmental
Management,” 42-17.6, "Administrative Penalties for
Environmental Violations" and 46-19, “Inspection of Dams
and Reservoirs” in accordance with the provisions of R.I. Gen.
Laws Chapter 42-35, “Administrative Procedures Act.”
1.3 Findings and Policy
A. The following
administrative findings are made as a basis for these rules and
regulations:
1. Rhode Island has
approximately six hundred and seventy-four (674) dams of varying age,
size and state of repair.
2. Failure or misoperation of
high hazard dams or significant hazard dams (both of which represent
approximately thirty percent (30%) of all dams in the state) will
result in a probable loss of human life or cause major economic loss,
disruption of lifeline facilities or impact other concerns.
3. Investigations of dam
failures have found that approximately sixty percent (60%) were
caused by lack of maintenance, resulting in piping, surface erosion,
slope protection damage or deterioration of outlet pipes.
4. Many of these dams, both
public and private, have not been properly maintained through the
years and pose a significant threat to public safety, real property
and natural resources.
5. Since dam related laws were
adopted, the threat to public safety, real property and natural
resources has increased due to deterioration of dams and development
in downstream areas over which dam owners do not necessarily have
control.
6. It is in the best interest
of the state, the cities and towns of the state, and the citizen's
thereof, to maintain a safe dam infrastructure.
7. In order to maintain a safe
dam infrastructure, a collaborative effort is required by state and
municipal officials, private dam owners and elected officials.
1.4 Application
The terms and provisions of
these rules and regulations shall be liberally construed to permit
the Department to effectuate the purposes of state law, goals and
policies. Nothing in these rules and regulations shall be deemed to
prohibit a dam owner or person maintaining or having control of a
dam, from seeking assistance from a municipality or prohibit a
municipality from assisting a dam owner in complying with these rules
and regulations.
1.5 Definitions
A. For the purposes of these
regulations the following terms shall have the following meanings:
1. "Appurtenant works”
means any ancillary feature of a dam including such structures as
dikes, training walls, spillways, either in the dam or separate there
from, low level outlet works, and water conduits such as tunnels,
channels, pipelines or penstocks, either through the dam or its
abutments.
2. "Control structure"
means a permanent feature of a dam that allows the water within the
reservoir to be lowered below the height of the spillway. Examples of
a control structure are a low level outlet, gate, valve or removeable
boards.
3. “Dam” means any
barrier made by humans, including appurtenant works that impounds or
diverts water.
4. “Department”
means the Department of Environmental Management and may be used
interchangeably with Director.
5. “Department dam
engineer” means an individual employed by the Department who
possesses a Bachelor of Science degree in engineering and has
demonstrated, through a combination of education, experience, and/or
training, that he/she is qualified to perform visual inspections.
6. “Detailed
investigation” means all studies, investigations and analyses
appropriate to evaluate the structural safety and hydraulic capacity
of a dam or reservoir and appurtenant works.
7. “Director”
means the Director of the Department of Environmental Management, or
his or her designee and may be used interchangeably with Department.
8. “Embankment”
means the fill material, including but not limited to rock or earth,
placed to provide a permanent barrier that impounds water.
9. “Freshwater wetlands”
means those areas as defined in R.I. Gen. Laws § 2-1-18, et
seq. , and the Wetlands regulations.
10. “Hazard
classification” means a rating for a dam that relates to the
probable consequences of failure or misoperation of the dam, which is
a determination made by the Director based on an assessment of loss
of human life, damages to properties or structures located downstream
of the reservoir, or loss of use as a drinking water supply. This
rating has no relationship to the current condition of the dam. A
higher hazard dam does not imply that it is more likely to fail or be
misoperated than a lower hazard dam.
11. “Height” means
the vertical distance from the elevation of the uppermost surface of
a dam to the lowest point of natural ground, including any stream
channel, along the downstream toe of the dam.
12. “High hazard dam”
means a dam where failure or misoperation will result in a probable
loss of human life.
13. “Hydraulic”
means the behavior of water relative to the dam. It is the manner in
which water in the reservoir is passed over or through the dam, via
an outlet such as a spillway or low level outlet.
14. “Hydrologic”
means the volume and speed at which precipitation flows along the
earth, combines into streams and discharges into a reservoir.
15. “Lifeline
facilities” means essential facilities, the loss of which can
result in indirect threats to life. Lifeline facilities may include
hospitals, transportation links (highways, bridges, airports, rail
lines, waterways, ports and harbor facilities and emergency
evacuation routes), and utility systems (electric power plants, gas
and liquid fuel pipelines, telecommunication systems, water supply
and waste water treatment facilities).
16. “Low hazard dam”
means a dam where failure or misoperation results in no probable loss
of human life and low economic losses.
17. “Maintenance”
means minor work on a dam necessary to maintain the dam in proper
working order, including activities such as filling minor erosion
areas, mowing or clearing vegetation provided that it does not affect
the integrity of the dam, lubricating and exercising equipment and
re-pointing masonry areas. Maintenance does not include repair of a
dam or substantial alteration of a dam.
18. “Owner” means
the person or persons, including any individual, firm, partnership,
association, syndicate, company, trust, corporation, municipality,
agency, political or administrative subdivision of the state or any
legal entity of any kind holding legal title to a dam.
19. “Person maintaining
or having control of a dam” means the person or persons,
including any individual, firm, partnership, association, syndicate,
company, trust, corporation, municipality, agency, political or
administrative subdivision of the state or any legal entity of any
kind having authority to operate or maintain a dam.
20. “Piping” means
the progressive development of internal erosion by seepage through
the dam. Piping appears downstream as a hole or a discharging flow of
water that includes soil particles from the dam embankment or
foundation.
21. “Probable loss of
human life” means loss of human life that is likely to occur,
or reasonably or realistically expected. This definition does not
include persons who are only incidentally in the potential inundation

recreating downstream of the dam provided the area is not an
established recreational area.
22. “Qualified engineer”
means a professional engineer fully registered in the State of Rhode
Island, who is experienced with dam inspection, design, construction
and repair.
23. “Registered owner”
means a dam owner who has been issued a certificate of registration
by the Department.
24. “Regulated dam”
means a low hazard dam that is six feet (6’) or more in height
or has fifteen (15) acre-feet or more of storage capacity; or a high
hazard dam; or a significant hazard dam. An acre-foot is a unit of
volume equal to forty-three thousand five hundred sixty (43,560)
cubic feet or three hundred twenty-five thousand eight hundred thirty
(325,830) gallons (a measure that would cover one (1) acre to a depth
of one foot (1’)).
25. “Removal”
means the destruction or breaching of a dam to the extent that the
dam no longer impounds or diverts water.
26. “Repair” means
any work performed at a dam that may affect the integrity of the dam,
including certain cutting or removal of trees where the resulting
decomposition of the tree root system could jeopardize the integrity
of the dam, work requiring excavation into the embankment fill or
foundation of a dam, work requiring reinforcement of the embankment
or work requiring removal or replacement of major structural
components of a dam; or any related, new, temporary or permanent
access way(s) that may be required within freshwater wetlands.
27. “Reservoir”
means the body of water that is impounded or diverted by a dam.
28. “Significant hazard
dam” means a dam where failure or misoperation results in no
probable loss of human life but can cause major economic loss,
disruption of lifeline facilities or impact other concerns
detrimental to the public’s health, safety or welfare. Examples
of major economic loss include but are not limited to washout of a
state or federal highway, washout of two (2) or more municipal roads,
loss of vehicular access to residences, (e.g. a dead end road whereby
emergency personnel could no longer access residences beyond the
washout area) or damage to a few structures.
29. “Spillway”
means a structure, a low area in natural grade or any part of the dam
which has been designed or relied upon to allow normal flow or major
flood flow to pass over or through while being discharged from a
reservoir.
30. “Substantial
alteration” means any physical modification to a dam that
results in a permanent change in the water elevation of the reservoir
or in water flow downstream of the dam.
31. “Unsafe dam”
means the condition of a regulated dam, as determined by the
Director, is such that an unreasonable risk of failure exists that
will result in a probable loss of human life or major economic loss.
Among the conditions that would result in this determination are:
excessive vegetation that does not allow the Director to perform a
complete visual inspection of a dam; excessive seepage or piping;
significant erosion problems; inadequate spillway capacity;
inadequate capacity and/or inoperable condition of control
structure(s); or serious structural deficiencies, including movement
of the structure or major cracking.
32. “Visual inspection”
means a visual, technical evaluation of the physical conditions of a
dam that affect performance of the structure.
33. “Wetlands
regulations” means the Rules and Regulations Governing the
Administration and Enforcement of the Freshwater Wetlands Act, Part
150-15-1
of this Title.
1.6 Responsibility of Dam Owners
A. All owners of high hazard
dams and significant hazard dams shall keep their dams and
appurtenant works in a safe condition.
B. All owners or precedent
owners are responsible for liability for damage to property of others

engineer that details the findings and analyses that support the
engineer’s opinion that the dam should be reclassified.
1.10 Approvals
A. Maintenance of a High or
Significant Hazard Dam
1. Maintenance of a high
hazard dam or significant hazard dam, except for certain cutting or
removal of trees, does not require an approval from the Department.
To be exempt from Department approval, the cutting or removal of
trees must be limited to those trees with a diameter less than six
inches (6”) (measured two feet (2’) above the ground
level) or that do not affect the integrity of the dam. If trees have
a diameter greater than six inches (6”) (measured two feet (2’)
above the ground level) then the dam owner shall first consult with a
qualified engineer who will determine if the cutting or removal could
jeopardize the integrity of the dam. The owner shall obtain a written
report from the qualified engineer, if the qualified engineer
determines that the cutting or removal is not a threat to the
integrity of the dam, and keep a copy of the report on file. The
report does not have to be filed with the Department. The owner shall
file an application for repair of the dam in accordance with these
rules and regulations if the qualified engineer determines that the
cutting or removal is a threat to the integrity of the dam. Mowing or
cutting of vegetation may be performed without an approval from the
Department provided it is limited to areas on the dam and adjacent to
the dam such that an area does not exceed fifteen feet (15’)
from the embankment, spillway or low level control structure. All
other mowing or cutting of vegetation within freshwater wetlands will
require a permit from the Director unless specifically exempted under
the Wetlands regulations. Areas exceeding fifteen feet (15’)
from the embankment, spillway or low level control structure that
have been historically mowed and maintained are specifically exempted
under the Wetlands regulations. These areas can continue to be mowed
without a permit from the Director.
2. All maintenance activities
shall comply with the following:
a. Best management practices
for erosion and sediment controls must be used. All controls must be
maintained in effective operating condition during the activity, and
all exposed soil and other fills must be permanently stabilized at
the earliest possible date. (For guidance see Rhode Island Soil
Erosion and Sediment Control Handbook and Rhode Island Stormwater
Design and Installation Standards Manual).
b. All equipment used for
maintenance activities shall be removed from any freshwater wetland
upon completion of the maintenance project.
c. All maintenance activities
shall be protective of water quality and freshwater wetland functions
and values so as to prevent pollutants, sediment, direct discharge of
stormwater runoff, or any material foreign to waters of the State
including freshwater wetlands, or hazardous to life, from entering
any waters of the State including freshwater wetlands.
B. Repair of a High or
Significant Hazard Dam
1. The dam owner must submit
an application for repair of a high hazard dam or significant hazard
dam directly to the Department’s Dam Safety Program.
Applications shall be in writing and on a form prescribed by the
Director and shall contain such documentation and information as the
Director may require, which may include but not be limited to the
following:
a. A locus map indicating the
location of the dam in relation to other fixed infrastructure in the
community such as roads, etc.
b. Written justification
explaining the need for the work.

h. Specifications of all
material to be used in the repair.
i. Estimated construction
schedule including commencement and completion of the repairs.
j. Amount (estimated vertical,
horizontal and areal) and schedule of reservoir drawdown and schedule
of reservoir recovery.
k. If a temporary water
by-pass or diversion is proposed, the dam owner shall provide plans,
details and calculations for such by-pass or diversion. The design of
the by-pass or diversion shall be capable of accommodating peak flows
from a minimum of ninety-five percent (95%) of all storm events that
may be expected to occur within the proposed construction period and
contain a contingency provision to safely accommodate a one hundred
(100) year, twenty-four (24) hour duration Type III storm event. The
design of the by-pass or diversion shall be capable of accommodating,
at a minimum, peak flows in accordance with the following table.

shall not exceed work beyond that necessary to abate the emergency.
e. Unless otherwise informed
by the Director, the dam owner must submit a report, a record drawing
and a permit application to the Department no later than thirty (30)
days following the emergency repair. The report must explain the
emergency repair undertaken, and the short-term and long-term effects
that the emergency repair had on abating the emergency, any wetlands
affected, any permanent, significant alteration which resulted from
the activity, and all restoration activities undertaken, or which may
still be required.
f. The time limitation for
performance of an emergency repair shall not exceed ten (10) days
following initial approval by the Department unless written approval
for an extension is obtained from the Department.
g. Following submission of the
record drawing required above, the applicant is required to comply
with any additional activities necessary to prevent significant
wetland alterations or to obtain a permit as detailed in writing by
the Department.
2. An emergency repair may be
taken by the owner or person maintaining or having control of a dam
without prior Department approval in accordance with § 1.12 of
this Part. The Department will evaluate the emergency repair to
determine if it is consistent with § 1.10(C) of this Part. The
Department will consider good faith efforts made by the owner or
person maintaining or having control of the dam to obtain prior
approval from the Department for the emergency repair.

of the dam and reservoir and to the municipality(s) in which the dam
and reservoir are located. In general, an abutter will be limited to
a property owner with frontage on the reservoir. The Director may
prescribe a form or a format for such notice.
F. Effect of Approval
1. The issuance of an approval
mandates compliance with all terms, conditions, management practices
and operation and maintenance requirements set forth in the approval.
2. The issuance of an approval
does not relieve any person of the continuing responsibility to
comply with any other applicable federal, state or local law or
regulation.
3. The issuance of an approval
does not relieve any person of the responsibility for obtaining any
other necessary permits or approvals from any federal, state,
regional, or local agency.
4. The issuance of an approval
does not authorize any injury to persons or property or invasion of
other private rights, or any infringement of federal, state or local
laws or regulations.
G. Modification, Suspension or
Revocation of Approval
1. The Director may modify,
suspend, or revoke, in whole or in part, an approval for cause,
including, but not limited to, the following:
a. Information indicating that
the project will result in an unsafe condition of the dam.
b. The existence of a factor
or factors which, if properly and timely brought to the attention of
the Director, would have justified the application of more or less
stringent conditions than required by these regulations, but only if
such factor(s) arose after the approval was issued.
c. Where circumstances on
which the approval was based have materially and substantially
changed since the approval was issued, including but not limited to
pertinent amendment of these rules and regulations.
d. The information or data
submitted by the dam owner either on the form required or in any
other material in support of the application is found to be false,
misleading or erroneous.
e. The project is not
undertaken in strict compliance with the conditions or provisions of
any approval issued by the Department.
2. A notice of
revocation/suspension of an approval will be in the form of a
certified letter notifying the dam owner of the revocation or
suspension and the reasons why the approval is being revoked or
suspended. Such notice shall be in conformance with the
Administrative Procedures Act, R.I. Gen. Laws §§ 42-35-9(b)
and 42-35-14.
3. The dam owner issued a
notice of revocation/suspension of an approval may request an
adjudicatory hearing to contest the revocation as set forth in the
provisions of § 1.15 of this Part. A notice of
revocation/suspension of an approval automatically becomes a final
order of the Director enforceable in Superior Court upon failure to
request said adjudicatory hearing.
4. Modification of an approval
shall be in accordance with § 1.10(B) of this Part.
1.11 Inspections
A. Scheduled Inspections
1. Regulated dams shall be
inspected in accordance with the following schedule. These time
periods are the maximum time between inspections and more frequent
inspections may be performed at the discretion of the Director.

2. The Director shall
periodically perform or require the owner to perform a visual
inspection of all high hazard dams and significant hazard dams. The
Director will notify the owner by certified letter in the event that
the Department will require the owner to perform a visual inspection
of the dam. The owner must then retain a qualified engineer to
perform a visual inspection of the dam. Visual inspection by a
qualified engineer must be completed within sixty (60) days following
receipt of notification from the Director.
3. At any time, the owner may
elect to employ the services of a qualified engineer to perform a
visual inspection of his or her dam.
4. Whenever the findings of
the visual inspection reveal, in the opinion of the Director, that
the dam may be unsafe, the owner shall be required to retain a
qualified engineer to perform a detailed investigation of the dam and
to provide a schedule by which any work needed shall be accomplished.
The owner shall be responsible for completing all work required by
the Director and in a reasonable time frame required by the Director.
5. Evaluations of regulated,
low hazard dams shall be conducted by the Director at least every
five (5) years to determine whether conditions have changed over time
that warrant raising the hazard classification to significant or
high. If the Director determines the classification of a low hazard
dam should be raised to significant or high, the owner shall be
informed of the classification change in accordance with §
1.9(B) of this Part.
B. Unscheduled Inspections
1. Any person who has cause to
believe that an unsafe dam exists may make a request to the Director
to inspect the dam. If in the opinion of the Director, the failure of
the dam will result in a probable loss of human life or cause major
economic loss, disruption of lifeline facilities or impact other
concerns detrimental to the public’s health, safety or welfare,
then the Director shall perform a visual inspection, or cause a
visual inspection to be performed, of the dam to determine if the dam
is unsafe.
2. The Director shall,
whenever he or she has cause to believe that an unsafe dam exists,
perform a visual inspection, or cause a visual inspection to be
performed, of the dam to determine if the dam is unsafe.
C. Inspections
1. Visual Inspections
A qualified engineer or a
Department dam engineer must perform a visual inspection. The visual
inspection shall include an assessment of the condition of the major
components of the dam subjectively rated as good, fair or poor. The
major components of a dam are the embankment(s), the spillway(s) and
the low level control structure(s). Good is defined as meeting
minimum guidelines, where no irregularities are observed and the
component appears to be maintained properly. Fair is defined as a
component that requires maintenance. Poor is defined as a component
that has deteriorated beyond a maintenance issue and requires repair;
the component no longer functions as it was originally intended.
2. Detailed Investigations
A qualified engineer must
perform a detailed investigation. A detailed investigation may
include soil analysis, concrete or earth stability analysis,
materials testing, foundation explorations, hydraulic and hydrologic
analysis, including basin studies, flood potential, and an analysis
of the dam’s ability to pass flood waters.
D. Inspection Reports
A report must be prepared for
each visual inspection or detailed investigation. If deficiencies are
found, the report must identify the specific deficiencies and, when
warranted, specify further investigation or corrective measures. The
report, completed by a qualified engineer retained by a dam owner,
must provide a recommended schedule to complete any work identified
as necessary to correct the deficiencies noted in the report. Such
reports must be provided to the dam owner and the Director within
thirty (30) days of the date of the visual inspection or within sixty
(60) days of the date of the detailed investigation.
1.12 Unsafe Dams
A. Whenever the Director
determines that a dam is unsafe the Director shall determine whether
the water in the reservoir shall be drawn off in whole or in part,
and the actions necessary to make the dam safe.
B. The Director shall notify
the owner or person maintaining or having control of the dam, by
certified mail, that the dam is unsafe, the actions necessary to make
the dam safe and a schedule to complete the actions.
C. The Director may notify the
owner or person maintaining or having control of the dam, by
certified mail that the dam is unsafe after completing his/her own

1.15 Appeals
A. The procedures for appeal
of Departmental decisions pursuant to the provisions of R.I. Gen.
Laws Chapter 42-35 are contained in the Rules
and Regulations for the Administration Adjudication Division ,
Part 10-00-1
of this Title.
B. Within thirty (30) days of
the receipt of a decision from the Department regarding an
application for repair of a dam or hazard classification of a dam,
the owner may request an adjudicatory hearing to appeal the decision,
or portions thereof. The request for an adjudicatory hearing must be
in writing, must comply in form and content for such requests as
required by Rules
and Regulations for the Administration Adjudication Division ,
Part 10-00-1
of this Title, and must be filed directly with the Administrative
Adjudication Division (AAD) of the Department. A copy of such request
must also be forwarded to the Dam Safety Program. A request for an
adjudicatory hearing automatically stays any contested approval
issued for repair of a dam. It shall be the dam owner’s burden
to demonstrate by a preponderance of the evidence that the
application as proposed or hazard classification is consistent with
the purposes of the law, complies with these rules and regulations
and protects the public, real property and natural resources.
C. Any person who has received
a Notice of Violation (NOV) alleging violation of these rules and
regulations, or whose approval has been suspended or revoked, may
appeal to the Director for review of the decision on which the NOV,
suspension or revocation is based by filing an appeal with AAD.
1. Filing of Appeal –
All appeals shall be in writing and shall be filed with and received
by AAD within twenty (20) days after the date of receipt of the
subject NOV, or within thirty (30) days after receipt of the
revocation or suspension.
2. Contents of Appeal –
Every appeal shall contain a detailed basis upon which the appeal is
taken.
1.16 Severability
If any provision of these
rules and regulations, or the application thereof to any person or
circumstances, is held invalid by a court of competent jurisdiction,
the validity of the remainder of the rules and regulations shall not
be affected thereby.
1.17 Superseded Rules and
Regulations
On the effective date of
these rules and regulations, all previous Rules and Regulations for
Dam Safety filed with the Secretary of State on December 20, 2007
shall be superseded. However, any enforcement action taken by, or
application submitted to, the Department prior to the effective date
of these rules and regulations shall be governed by the rules and
regulations in effect at the time the enforcement action was taken,
or application filed.
1.18 Appendix I: Impact Avoidance
and Minimization
A. Rhode Island’s
Freshwater Wetlands Act, R.I. Gen. Laws § 2-1-18, et seq. ,
and Water Pollution Act, R.I. Gen. Laws § 46-12-1, et seq.
require the Director to protect freshwater wetland values and water
quality, respectively. It is important for the dam owner to recognize
the Director’s responsibilities under these laws and to plan
his/her repair projects to minimize any negative impacts to
freshwater wetlands and water quality values. In particular, the dam
owner must:
1. Minimize the impacts from
lowering the water elevation in a reservoir during a repair project,
such as by installing a temporary cofferdam. This is necessary to
reduce detrimental impacts to fish and wildlife associated with the
wetland environment and to reduce loss of aquatic vegetation that
serves as wildlife habitat. In the event that a dam owner is unable
to install controls to maintain water in the reservoir to assist in
protecting fish and wildlife habitat, the dam owner must specifically
inform the Director of this situation and document in writing why
water is not proposed to be maintained upstream of the dam during the
repair activity. Efforts must be made to avoid drawdowns between
April 15 to July 1, and to avoid significant drawdowns between
October 15 and March 15.
2. Use best management
practices regarding the installation of sediment and erosion controls
to prevent sediment from entering adjacent waters of the state.
3. Minimize construction
disturbance so as to keep disturbed soils and areas subject to
erosion to a minimum.
4. Prevent any hazardous
substances injurious to aquatic life used during the repair activity
from entering any adjacent water and freshwater wetlands.
5. Stabilize all disturbed
soils following construction activities to ensure erosion will not
take place.
6. Minimize clearing of
vegetation to that necessary to conduct the project and remove the
slash material from adjacent freshwater wetlands and water bodies.
7. Use only the amount of fill
of other material necessary to complete the project and minimize the
placement of material in any flood plain.
8. Replace, restore or
mitigate alterations to freshwater wetlands as deemed necessary in
the opinion of the Department.
