Every person owning or operating an underground facility shall assist excavators and the general public in determining the location of underground facilities before excavation activities are begun or as may be required by subsection 6 of section 319.026 or subsection 1 of section 319.030 after an excavation has commenced. Methods of informing the public and excavators of the means of obtaining such information may, but need not, include advertising, including advertising in periodicals of general circulation or trade publications, information provided to professional or trade associations which routinely provide information to excavators or design professionals, or sponsoring meetings of excavators and design professionals for such purposes. Information provided by the notification center on behalf of persons owning or operating an underground facility shall be deemed in compliance with this section by such persons.

2. Every person owning or operating underground pipeline facilities shall, in addition to the requirements of subsection 1
of this section:

(1) Identify on a current basis persons who normally engage in excavation activities in the area in which the pipeline is located. Every such person who is a participant in a notification center shall be deemed to comply with this subdivision if such notification center maintains and updates a list of the names and addresses of all excavators who have given notice of intent to excavate to such notification center during the previous year and provided the notification center shall, not less frequently than annually, provide public notification and actual notification to all excavators on such list of the existence and purpose of the notification center, and procedures for obtaining information from the notification center;

(2) Either directly or through the notification center, notify excavators and the public in the vicinity of his or her underground pipeline facility of the availability of the notification center by including the information set out in subsection 1 of section 319.025 in notifications required by the safety rules of the Missouri public service commission relating to its damage prevention program;

(3) Notify excavators annually who give notice of their intent to excavate of the type of marking to be provided and how to identify the markings.

Excavator must give notice and obtain information, when, how—notice to notification center, when--clarification of markings, response--permit for highway excavation required.
319.025 . 1. Except as provided in subsection 4 of section 319.030 and in section 319.050 , a person shall not make or begin any excavation in any public street, road or alley, right-of-way dedicated to the public use or utility easement of record or within any private street or private property without first giving notice to the notification center and obtaining information concerning the possible location of any underground facilities which may be affected by said excavation from underground facility owners whose names appear on the current list of participants in the notification center and who were communicated to the excavator as notification center participants who would be informed of the excavation notice. Notice to the notification center of proposed excavation shall be deemed notice to all owners and operators of underground facilities. The notice referred to in this section shall comply with the provisions of section 319.026 .

2. An excavator’s notice to owners and operators of underground facilities participating in the notification center pursuant to section 319.022 is ineffective for purposes of subsection 1 of this section unless given to such notification center.

3. Notification center participants shall be relieved of the responsibility to respond to a notice of intent to excavate received directly from the person intending to commence an excavation, except for requests for clarification of markings through on-site meetings as provided in subsection 1 of section 319.030 and requests for locations at the time of an emergency as provided by section 319.050 .

4. Notwithstanding the provisions of this section to the contrary, a person shall not make or begin any excavation in any state highway, or on the right-of-way of any state highway, without first obtaining a permit from the state highways and transportation commission pursuant to section 227.240 , provided however, the provisions of this subsection shall not apply to railroad right-of-way owned or operated by a railroad.

Notice of excavator, form of--written record maintained—incorrect location of facility, duty of excavator--visible markings necessary to continue work--damage, dislocation, or disturbance, notification and reporting requirements--annual report of damages required, by whom.
319.026 . 1. An excavator shall serve notice of intent to excavate to the notification center by toll-free telephone number operated on a twenty-four hour per-day, seven day per-week basis or by facsimile or by completing notice via the internet at least two working days, but not more than ten working days, before the expected date of commencing the excavation activity. The notification center receiving such notice shall inform the excavator of all notification center participants to whom such notice will be transmitted and shall promptly transmit all details of such notice provided under subsection 2 of this section to every notification center participant in the area of excavation.

2. Notices of intent to excavate given pursuant to this section shall contain the following information:

(1) The name and telephone number of the person filing the notice of excavation, if the telephone number is different than that of the excavator, and the name, address, telephone number of the excavator and whether the excavator’s telephone is equipped with a recording device;

(2) The date the excavation activity is expected to commence, the depth of planned excavation and, if applicable, that the use of explosives is anticipated on the excavation site, and the type of excavation being planned, including whether the excavation involves trenchless excavation;

(3) The facsimile number, email address, and cellular telephone number of the excavator, if any;

(4) The name of the person primarily responsible for conducting the excavation or managing the excavation process, and if any of the information stated in subdivision (1) or (3) of this subsection is different for the person primarily responsible for the excavation, the notice shall also state the same information for that person;

(5) A detailed description accepted by the notification center sufficient for the location of the excavation by any one or more of the following means: by reference to a specific street address, or by description of location in relation to the nearest numbered, lettered, or named state or county road or city street for which a road sign is posted, or by latitude and longitude including the appropriate description in degrees, minutes, and seconds, or by state plane coordinates;

(6) A description of the site of excavation by approximate distance and direction from the nearest state or county road or city street or intersection of such roads or streets unless previously provided under subdivision (5) of this subsection, and the proximity of the site to any prominent landmarks;

(7) A description of the location or locations of the excavation at the site described by direction and approximate distance in relation to prominent features of the site, such as existing buildings or roadways;

(8) Directions as to how to reach the site of the excavation from the nearest such road, if the excavation is not on or near a posted numbered, lettered, or named state or county road or city street.

3. The notification center receiving such notice shall solicit all information required by subsection 2 of this section and shall require the excavator to provide all such information before notice by the excavator is deemed to be completed pursuant to sections 319.015 to 319.050 . The notification center shall transmit all details of such notice as required by this section.

4. A record of each notice of intent to excavate shall be maintained by the notification center for a period of five years. The record shall include the date the notice was received and all information required by subsection 2 of this section which was provided by the excavator and a record of the underground facility owners notified by the notification center. If the notification center creates a record of the notice by telephonic recording, such record of the original notice shall be maintained for one year from the date of receipt. Records of notices to excavate maintained by the notification center in electronic form shall be deemed to be records under this subsection. Persons holding records of notices of intent to excavate and records of information provided to the excavator by the notification center or owner or operator of the facility shall make copies of such records available for a reasonable copying fee upon the request of the owner or operator of the underground facilities or the excavator filing the notice.

5. If in the course of excavation the person responsible for the excavation operations discovers that the owner or operator of the underground facility who is a participant in a notification center has incorrectly located the underground facility, he or she shall notify the notification center which shall inform the underground facility owner. The underground facility owner shall respond to the incorrect locate notification within two hours of receipt of the notification by contacting the person responsible for the excavation or by correctly locating their underground facility. The person responsible for maintaining records of the location of underground facilities for the notification center participant shall correct such records to show the actual location of such facilities, if current records are incorrect.

6. When markings have been provided in response to a notice of intent to excavate, excavators may commence or continue to work within the area described in the notice for so long as the markings are visible. If an excavator is unable to begin the excavation within ten working days as described in the request, the excavator shall make a relocate request before beginning the excavation. If markings become unusable due to weather, construction or other cause, the excavator shall contact the notification center to request remarking. Such notice shall be given in the same manner as original notice of intent to excavate, and the owner or operator shall remark the site in the same manner, within the same time, as required in response to an original notice of intent to excavate. Each excavator shall exercise reasonable care not to unnecessarily disturb or obliterate markings provided for location of underground facilities. If remarking is required due to the excavator’s failure to exercise reasonable care, or if repeated unnecessary requests for remarking are made by an excavator even though the markings are visible and usable, the excavator may be liable to the owner or operator for the reasonable cost of such remarking. Nothing in this section shall allow any person other than the facility owner or their representative to mark or relocate any underground facility.

7. Before commencing excavation, the excavator shall determine best practices for confirming the horizontal and vertical location
of facilities at the site of excavation considering conditions at the site including geology, access to the site, and the presence of paved surfaces. Hand digging or soft digging shall be used as a best practice when possible.

8. In the event of any damage, dislocation, or disturbance of any underground facility in connection with any excavation, the person responsible for the excavation operations shall notify the notification center. This subsection shall be deemed to require reporting of any damage, dislocation, or disturbance to trace wires, encasements, cathode protection, permanent above-ground stakes, or other such items utilized for protection of the underground facility. The excavator shall immediately contact 911 when any damage or contact with a pipeline results in a release from the pipeline of hazardous liquid or gas to occur.

9. In the event of any damage, dislocation, or disturbance to any underground facility or any protective devices required to be reported by the excavator under subsection 8 of this section in advance of or during the excavation work, the person responsible for the excavation operations shall not conceal or attempt to conceal such damage, dislocation, or disturbance, nor shall that person attempt to make repairs to the facility unless authorized by the underground facility owner. In the case of sewer lines or facilities, emergency temporary repairs may be made by the excavator after notification without the owners’ or operators’ authorization to prevent further damage to the facilities. Such emergency repairs shall not relieve the excavator of responsibility to make notification as required by subsection 8
of this section.

10. No later than April 1, 2015, and each year thereafter, each underground facility owner who owns or operates electric, gas, or pipeline facilities shall submit to a central repository designated by the notification center a report of damages experienced by its facilities for the prior calendar year. The notification center shall determine the minimum information to be reported. All data submitted shall be aggregated and anonymous. Information provided by the underground facility owner specific to damage data submitted shall be accessible only to the underground facility owner unless otherwise designated by the underground facility owner.

Design requests, how made--marking location required.
319.027 . 1. Any person may make design requests by contacting the notification center. Such design requests shall include all information deemed necessary by the notification center to complete the notice, including the identification of the person and a description of the location of the project being designed and other information similar to that required of excavators under section 319.026 .

2. Design requests shall be made to the notification center at least five working days, but not more than ten working days, before the date the person has requested receiving the information from the underground facility owner. Upon receipt of a design request, the notification center shall inform the person of the name of all notification center participants to whom the notice will be transmitted and shall promptly transmit such notice to the appropriate underground facility owners.

3. Every underground facility owner who receives a design request shall mark the location of the facility, or contact the person making the request, within five working days after the date the notice was received from the notification center. If the person making the request was contacted as an alternative to marking location,
the person and the underground facility owner shall mutually agree on a schedule and method for providing the information, provided that the facility shall be marked within five working days if the facility owner and the person making the request are
unable to agree.

4. No excavation may be commenced based upon information received through a design request. Obtaining information through a design request shall not excuse any person commencing an excavation from making notice and obtaining information under sections 319.025 and 319.026 concerning the possible location of any underground facilities which may be affected.

Notification of location of underground facility, when, how—failure to provide notice of location, effect.
319.030 . 1. Every person owning or operating an underground facility to whom notice of intent to excavate is required to be given shall, upon receipt of such notice as provided in this section from a person intending to commence an excavation, inform the excavator as promptly as practical, but not in excess of two working days, unless the excavator agrees to extend the start date and time provided in the locate request through methods established by the notification center, of the approximate location of underground facilities in or near the area of the excavation so as to enable the person engaged in the excavation work to locate the facilities in advance of and during the excavation work, provided that no excavation shall begin earlier than the scheduled excavation date provided on the locate request unless the excavator has confirmed that all underground facilities have been located. The two working days provided for notice in this subsection and subsection 1 of section 319.026 shall begin at 12:00 a.m. following the receipt of the request by the notification center. Each underground facility owner receiving notifications from the notification center by use of the internet shall, after December 31, 2014, use the locate status system provided by the notification center. Those underground facility owners that do not receive notifications by use of the internet shall, no later than January 1, 2016, provide locate status to the notification center by an alternate method provided by the notification center. If the excavator states in the notice of intent to excavate that the excavation will involve trenchless technology, the owner or operator shall inform the excavator of the depth, to the best of his or her knowledge or ability, of the facility according to the records of the owner or operator. The owner or operator shall provide the approximate location of underground facilities by use of markings as designated in section 319.015 . Persons representing the excavator and the owner or operator shall meet on the site of excavation within two working days of a request by either person for such meeting for the purpose of clarifying markings, or upon agreement of the excavator and owner or operator, such meeting may be an alternate means of providing the location of facilities by originally marking the approximate location of the facility at the time of the meeting. If upon receipt of a notice of intent to excavate, an owner or operator determines that he or she neither owns or operates underground facilities in or near the area of excavation, the owner or operator shall within two working days after receipt of the notice, inform the excavator that the owner or operator has no facilities located in the area of the proposed excavation. The owner or operator of the underground facility shall make notice to the excavator that no facilities are located in the area of excavation by contacting the excavator by any of the following methods:

(1) By calling the primary number of the excavator or by calling the telephone number of the responsible person as provided by the excavator under subdivision (4) of subsection 2 of section 319.026 ;

(2) By leaving a message on the recording device for such numbers;

(3) By calling the cellular telephone number of the excavator or responsible person;

(4) By notifying the excavator by facsimile or electronic mail at numbers or addresses stated by the excavator in the notice of excavation made under subsection 2 of section 319.026 ;

(5) By marking “clear” or “OK” at the site of excavation;

(6) By verbally informing the excavator in person.
If the only means of contacting the excavator is one or more telephone numbers provided by the excavator in the notice of excavation under section 319.026 , then two attempts by the underground facility owner to contact the excavator at one of the telephone numbers provided shall constitute compliance with this subsection; or

(7) By use of a locate status system.

2. A record of the date and means of informing the excavator that no facilities were located by the owner or operator shall be included in the written records of the underground facility owner regarding each specific notice of excavation and shall be retained for a period of five years.

3. If the owner or operator notifies the excavator that the area of excavation cannot be determined from the description provided by the excavator through the notice required by this section, the excavator shall provide clarification of the area of excavation by marking the area with white flags or white paint, or by providing project plans to the owner or operator, or by meeting on the site of the excavation with representatives of the owner or operator as provided for in this section.

4. In the event that a person owning or operating an underground facility fails to comply with the provisions of subsection 1 of this section after notice given by an excavator in compliance with section 319.026 , the excavator, prior to commencing the excavation, shall give a second notice to the notification center as required by section 319.026 stating that there has been no response to the original notice given under section 319.026 .
After the receipt of the notice stating there has been “no response”, the owner or operator of an underground facility shall, within two hours of the receipt of such notice, mark its facilities or contact and inform the excavator of when the facilities will be marked; provided, however, that for “no response” notices made to the notification center by 2:00 p.m., the markings shall be completed on the working day the notice is made to the notification center, and provided that for “no response” notices made to the notification center after 2:00 p.m., the markings shall be completed no later than 10:00 a.m. on the next working day.

If an underground facility owner fails to mark its facilities or contact the excavator as required by this subsection, the excavator may commence the excavation. Nothing in this subsection shall excuse the excavator from exercising the degree of care in making the excavation as is otherwise required by law.

5. For purposes of this section, a period of two working days begins at 12:00 a.m. following when the request is made.

Sewer system owner duties upon notification  of intent to excavate.
319.031 . 1. In addition to the other requirements of section 319.030 , the response to a notice of intent to excavate received by a sewer system owner, when such owner has underground facilities located in the area of excavation identified in the notice and when the notice indicates that trenchless excavation methods will be used, shall include a determination of whether sewer service connections exist in the area of the excavation.

2. If the sewer system owner determines that sewer service connections exist in the area of the excavation identified in a notice of intent to excavate, the owner shall provide his or her best available information, or notice that the information does not exist, regarding the location of such connections to the excavator by any of the following methods:

(1) Placing a triangular green mark at the approximate location of the sewer service connection pointing in the direction of the customer structure serviced;

(2) Providing electronic copies of the information to the excavator;

(3) Delivering copies of the information to the excavator by facsimile or by other agreed upon means; or

(4) Arranging to meet the excavator at the site of the excavation to provide the information.

3. Providing the best available information, or notice that the information does not exist, regarding the location of sewer service connections that exist in the area of excavation identified in a notice of intent to excavate shall constitute full compliance with this section, and a sewer system owner shall not be liable to any party for damages or injuries resulting from an excavation if they are in compliance with this section.

4. Providing the best available information regarding the location of sewer service connections that exist in the area of excavation identified in a notice of intent to excavate shall not in and of itself constitute ownership, operation, control, or management of sewer service lines by a sewer system owner.

Public right-of-way, installation within, requirements.
319.033 . By January 1, 2016, if new lateral sewer pipes or water service lines are installed and connected to an underground facility within the public right-of-way, as defined in section 319.015 , or if such infrastructure is fully replaced by excavation within the public right-of-way, the facility owner shall be required to place tracer wire or other utility location technology and an access point within a protective enclosure over water lines and cleanouts for gravity sewer laterals. For sewer laterals operating under pressure or vacuum, the facility owner shall be required to place an access point within a protective enclosure and shall not be required to place a cleanout. All protective enclosures and cleanouts shall be extended to grade and installed so that it is easily accessible. For water service lines and sewer laterals operating under pressure or vacuum, tracer wire, or other utility location technology, shall be placed within the protective enclosure to provide approximate location of the underground facilities in these areas that are located within a public right-of-way. An underground facility owner shall not be liable to any party for damages or injuries resulting from an excavation if they are in compliance with this section. This section shall apply to all installations of water service lines and sewer laterals without regard to their status as underground facilities under section 319.015 . Nothing in this section shall require any owner of underground facilities who is not otherwise required under sections 319.010 to 319.050 to become a notification center participant.

Compliance with law still requires excavation to be made in careful and prudent manner failure to give notice or mark facilities, rebuttable presumption of negligence.
319.035 . 1. Obtaining information as required by sections 319.010 to 319.050 does not excuse any person making any excavation from doing so in a careful and prudent manner.

2. Nothing in sections 319.010 to 319.050 shall relieve an excavator from the obligation to excavate in a safe and prudent manner, nor shall it absolve an excavator from liability for damage to underground facilities.

3. The failure of any excavator to give notice of proposed excavation activities as required by this chapter shall be a rebuttable presumption of negligence on his or her part in the event that such failure shall cause injury, loss, or damage. In addition to any penalties provided herein, liability under common law may apply.

4. The failure of an underground facility owner to mark his or her facilities that are located in an area of excavation described in a notice of intent to excavate received by the underground facility owner, as required by section 319.030 , or the failure of an underground facility owner to be a notification center participant, consistent with the provisions of section 319.022 , shall be a rebuttable presumption of negligence on the part of such owner in the event that such failure shall cause injury, loss, or damage. In addition to any penalties provided herein, liability under common law may apply.

Excavation sites included in requirements--equipment prohibited at such sites.
319.037 . 1. Notwithstanding any other provision of law to the contrary, the procedures and requirements set forth in this section shall apply on the site of any excavation involving trenchless excavation, including directional drilling, where the approximate location of underground facilities has been marked in compliance with section 319.030 and where any part of the walls of the intended bore are within the marked approximate location of the underground facility.

2. The excavator shall not use power-driven equipment for trenchless excavation, including directional drilling, within the marked approximate location of such underground facilities until the excavator has made careful and prudent efforts to confirm the horizontal and vertical location thereof in the vicinity of the proposed excavation through methods appropriate to the geologic and weather conditions, and the nature of the facility, such as the use of electronic locating devices, hand digging, pot holing when practical, soft digging, vacuum methods, use of pressurized air or water, pneumatic hand tools or other noninvasive methods as such methods are developed.
Such methods of confirming location shall not violate established safety practices. Nothing in this subsection shall authorize any person other than the owner or operator of a facility to attach an electronic locating device to any underground facility. For excavations paralleling the underground facility, such efforts to confirm the location of the facility shall be made at careful and prudent intervals. The excavator shall also make careful and prudent efforts by such means as are appropriate to the geologic and weather conditions and the nature of the facility, to confirm the horizontal and vertical location of the boring device during boring operations. Notwithstanding the foregoing, the excavator shall not be required to confirm the horizontal or vertical location of the underground facilities if the excavator, using the methods described in this section, excavates a hole over the underground facilities to a depth two feet or more below the planned boring path and then carefully and prudently monitors the horizontal and vertical location of the boring device in a manner calculated to enable the device to be visually observed by the excavator as it crosses the entire width of the marked approximate location of the underground facilities.

No abrogation of contractual obligations with railroads.
319.042 . Notwithstanding any provision of law to the contrary, nothing in this chapter shall abrogate any contractual provisions entered into between any railroad and any other party owning or operating an underground facility within the railroad’s right-of-way. For railroads regulated by the Federal Railroad Administration, sections 319.015 to 319.050 shall not include any underground facility owned or operated by a railroad on land which the railroad owns or any excavation done by a railroad when such excavation is done entirely on land which the railroad owns.

Civil penalties--attorney general may bring action and shall make public number of enforcement actions.
