Directional Drilling Insurance in South Dakota

Most states decide a strike by asking what the excavator did. South Dakota asks first what the operator did — and the answer puts you into one of two liability regimes that are not close to each other.

If the locate came back on time and was good enough, you are strictly liable for all damage your bore proximately causes. If it was late, or wrong, you are not liable at all except on proof of negligence. Nothing about your own care moves you between those two; the marking does. What follows is that binary and the statute around it. The marking decides the liability and SDCL 56-3-18 decides the clause. What the marking is protecting is on the Directional Drilling Insurance pillar and the pollution liability page.

The number that does three jobs

Eighteen inches appears three times in SDCL 49-7A-8, doing something different each time, and a crew that knows only one of them is exposed on the other two.

It is the operator’s accuracy standard. On receipt of notice the operator must advise the excavator of the location of its facilities by marking with stakes, flags, paint or other clearly identifiable markings within eighteen inches horizontally from the exterior sides of the facilities.

It is your clearance duty. Excavators must maintain a minimum horizontal clearance of eighteen inches between a marked facility and the cutting edge of any mechanical equipment.

And it is the hand-dig trigger. Where excavation is required within eighteen inches horizontally, the excavator must expose the facility with hand tools or noninvasive methods approved by rule, and protect and support it before further mechanical excavation.

Read together, those three uses describe a corridor. The operator’s mark is accurate to eighteen inches, so the facility may sit anywhere in a three-foot band; your equipment must stay eighteen inches clear of the mark; and entering that band at all converts the work from mechanical to hand or noninvasive method. Both §49-7A-5 and §49-7A-8 were amended by SL 2026, ch 183, so procedures written against the older text should be re-read.

Forty-eight hours that do not start when you call

Under SDCL 49-7A-5 no excavator may begin any excavation without first notifying the one-call notification center, with notice given at least forty-eight hours before commencement. The section then fixes the start of that clock: the period begins at 12:01 a.m. the day after notice is submitted, excluding any Saturday, Sunday, or legal holiday of the state.

The consequence is that the hour of your call does not matter. A ticket placed at eight in the morning and one placed at five in the evening start counting at the same minute, and a Friday call spends the weekend outside the count. Crews used to states where the clock runs from the call itself routinely lose a day here without noticing.

The operator’s side runs on the same period, but with a wrinkle that runs in your favor if you use it deliberately. Under §49-7A-8 the operator’s response time is the later of the forty-eight-hour period, or the period between notice being given and the excavation start time the excavator provided. Nominating a realistic later start does not shorten the operator’s window — it lengthens it, which is the opposite of the pressure most schedules apply.

Strict liability, or none at all

This is the provision that should shape how a South Dakota file is built.

If the locate was good. Under SDCL 49-7A-10, where the requested information was provided within the time specified and sufficiently identifies the location of the facilities in accordance with §49-7A-8, an excavator damaging or injuring them is strictly liable for all damage proximately caused. There is no fault question. Care, method and experience do not enter into it.

If the locate was not. Under SDCL 49-7A-9, where markings are not provided within the time specified, or where the markings provided fail to identify the location in accordance with statute and rule, an excavator damaging the facilities is not liable except on proof of negligence.

Those two sentences hand the whole question to the marking. Whether you face automatic liability for every dollar or a claimant who must first prove you were careless is decided by whether someone else’s paint arrived on time and landed within eighteen inches.

What follows for practice is unusually clear. The most valuable minutes on a South Dakota job are the ones spent photographing the marks against the clock and against the line as found — because that record is not evidence about your conduct, it is evidence about which statute applies to you. Section 49-7A-10 closes with the necessary caveat: compliance with the chapter does not excuse a person from acting in a careful and prudent manner, and does not disturb civil remedies otherwise available except as the chapter specifically provides.

Disturbed counts, concealment does not

Under SDCL 49-7A-12 the duty triggers on damage that is easy to under-report: if a facility is damaged, dislocated, or disturbed in advance of or during the work, the excavator must immediately notify the center and, if known, the operator. A bore that shifts a line without breaching it is inside that language.

The section then states two prohibitions without qualification. No excavator may conceal or attempt to conceal any damage, dislocation or disturbance. And no excavator may attempt any repair unless authorized by the operator. Where the event releases flammable, toxic or corrosive gas or liquid, the excavator must call 911 and notify the center and the operator.

Section 49-7A-13 adds the reporting duty that runs the other way: an excavator who cannot locate a facility, or who discovers that the operator located it incorrectly, must promptly notify the operator or the center. That is the notification that builds the §49-7A-9 record while the crew is still standing over the hole.

Anyone may complain, and the answer is the record

Under SDCL 49-7A-17 any person with a complaint against a party who violates, or who procures, aids or abets a violation of, §49-7A-2, §49-7A-5, §49-7A-8 or §49-7A-12 may apply to the board for relief — and no complaint may be dismissed because of the absence of direct damage to the complainant. Standing is expressly waived rather than merely unaddressed.

Timing runs the other way. Under §49-7A-21 a complaint must be brought not later than ninety days after discovery of the alleged violation, and in no case more than one year after the date of the violation — except a complaint under §49-7A-12, which must be brought within one year of discovery.

Then the procedural fact that decides most matters. Under §49-7A-22 a panel of three or five board members determines whether probable cause exists. Under §49-7A-23 the panel forwards the complaint with notice requiring the respondent to satisfy or answer in writing within twenty days. And under §49-7A-25 the probable-cause determination is made solely on those submissions — no other evidence may be considered.

A contractor’s written answer is therefore the entire evidentiary record at the stage where the matter is most likely to end. There is no hearing at which to produce the photographs unless someone requests one under §49-7A-27 within twenty days, and failure to request is treated as acceptance. Under §49-7A-26 the penalty considers the damage and threat to public safety, the respondent’s plans and procedures to insure future compliance, any history of previous violations, and other matters as justice requires — so a documented program is an input to the figure rather than mitigation offered afterwards.

The board hearing it is set by §49-7A-3 at eleven members serving without pay, with seats enumerated by constituency — and two of them represent contractors who perform excavation services. Under §49-7A-34 any order carries a presumption of validity, with the burden on the party claiming invalidity.

Penalties, and the multiplier

Under SDCL 49-7A-18 a violation may be assessed at up to $1,000 for the first and up to $5,000 for each subsequent violation occurring within twelve months. Under §49-7A-19 an intentional violation runs to $5,000 and $10,000 on the same twelve-month structure.

The figure that matters most is neither. Under §49-7A-20, each violation constitutes a separate offense, and in the case of a continuing violation each day the violation continues constitutes a separate violation. An uncorrected condition is not one assessment; it is one per day for as long as it stands. That converts a modest ceiling into an open-ended exposure and makes the speed of correction the variable worth managing.

Neither the certificate nor the care of the crew

The contractors who reach us in South Dakota are usually mid-project, holding a certificate a prime has refused and an agent who cannot explain why re-issuing it will not help. What decides money here is not the certificate and not the crew’s care. Because §49-7A-10 imposes strict liability where the locate was adequate while §49-7A-9 requires proof of negligence where it was not, and because §49-7A-25 lets probable cause be decided on the papers alone, the locate photographs and the twenty-day written answer are worth more than any other document in the file. Photograph the marks, and never let the answer go in thin.

Pollution liability sits outside chapter 49-7A. The chapter governs damage to facilities and the complaint process that follows; drilling fluid surfacing into a river, a stock dam or a wetland is an environmental loss the general liability form excludes, and strict liability under §49-7A-10 does not reach it either way. Contractors equipment matters because the eighteen-inch hand-dig trigger converts mechanical progress into manual work at exactly the points where a route is most congested. General liability is specified against the contract — and here the contract statute is the shortest in this series.

The shortest list in this series, and what that leaves open

What §56-3-18 does. SDCL 56-3-18 makes void and unenforceable, as against the policy of the law, a covenant in or collateral to a contract relative to the construction, alteration, repair or maintenance of a building, structure, appurtenance and appliance — including moving, demolition and excavating connected therewith — purporting to indemnify the promisee against liability for damages arising out of bodily injury or property damage caused by or resulting from the sole negligence of the promisee, its agents or employees, or indemnitee. Its source is a single 1973 session law.

The line is sole negligence, so a broad clause survives wherever the contractor is also at fault — the same line Idaho, Maryland and South Carolina draw. And like Idaho’s, this section carries no savings clause for insurance: it does not preserve the validity of an insurance contract, and it does not void a requirement that you procure one. It simply does not address the subject, and we are not going to tell you what follows from that.

What is missing from the list is the part worth noticing. The enumerated work is a building, a structure, an appurtenance and an appliance. That is all of it. There is no highway, which Idaho has; no road, which North Carolina, South Carolina and Rhode Island have; no bridge or water line or sewer line, which Louisiana and Kansas have; and no closing catch-all for other improvements to real property, which Montana has. It is the barest version of this enumeration we have read.

So the boundary question that runs through this family arrives here in its sharpest form, and we have not located a South Dakota decision construing this language as applied to utility, linear or fiber work. A bore in a public right-of-way is not obviously connected with a building or an appliance, and the words the legislature might have used to reach it are the very words absent from the section. We are not going to resolve that for you, because a shorter list is an argument and not a holding, and pricing a subcontract against an argument is how a contractor ends up uninsured for the thing that actually happens. What is settled — the sole-negligence line, and the silence on insurance — is settled regardless.

Strict liability or none at all, decided by the marking rather than by the crew care, is a rule about one excavation. What a South Dakota program carries besides is on our South Dakota fiber contractor insurance page.

What we actually do on a South Dakota file: photograph the marks against the clock and against the line as found, because §49-7A-9 and §49-7A-10 make that record the thing that decides whether strict liability or a negligence standard applies; count the forty-eight hours from 12:01 a.m. the day after the call rather than from the call; nominate a realistic start date, since under §49-7A-8 a later start lengthens the operator’s window rather than shortening it; treat the twenty-day written answer under §49-7A-23 as the whole record, because §49-7A-25 says probable cause is decided on nothing else; correct an uncorrected condition immediately, since §49-7A-20 makes every additional day a separate violation; and read the subcontract knowing §56-3-18 stops at sole negligence, says nothing about insurance, and lists less work than any comparable statute in this series. If a prime is asking for an additional-insured endorsement, send it — this statute will not answer that for you.
