Several residents of Combs, Kentucky, appellees, brought this suit against defendant appellants to recover property damages allegedly caused by the negligent operation of appellants’ coal tipple. The jury awarded the aggregate sum of $13,100. On this appeal appellants contend (1) the claims were barred by the statute of limitations, and (2) there was a failure of proof on the proper measure of damages.
It is conceded appellants’ operation constituted a nuisance, resulting from the expulsion of excessive amounts of coal dust in the community. The nature of this nuisance is the controlling consideration in deciding both questions raised on this appeal.
The parties assume that the five year statute, KRS 413.120, is the governing one. It would, however, bar appellees’ claims only if the condition created by appellants constituted a
permanent nuisance.
Kentucky West Virginia Gas Company v. Matny, Ky.,
The briefs indicate some confusion exists with respect to the basic question involved. 1 Appellants contend that since this was a permanent structure, the nuisance, if any, was a permanent one; whereas, ap-pellees contend that this is a temporary structure because it was negligently operated. It is not the nature of the structure which is determinative of the issue but the nature of the nuisance.
It is true a temporary structure cannot be a permanent nuisance. On the other hand, a permanent structure may create a temporary nuisance. Madisonville, H. & E. R. Co. v. Graham,
A permanent structure properly constructed and properly operated may con

stitute a nuisance. Louisville Refining Company v. Mudd, Ky.,
A permanent structure may, however, constitute or create a temporary nuisance. We have said this occurs when the structure has been negligently constructed, or negligently operated. Madisonville, H. & E. R. Co. v. Graham,
To begin with, negligence is not an essential element of the plaintiff’s cause of action. Defendant’s liability is not based on the failure to exercise due care, but arises from the unreasonableness of the use of his property in the light of the gravity of harm to the plaintiff. Louisville Refining Company v. Mudd, Ky.,
For reasons difficult to understand, we have held it necessary to prove negligence in
blasting
cases where the damage was caused by concussions or vibrations as opposed to the casting of physical objects on the plaintiff’s land. See Aldridge-Poage, Inc. v. Parks, Ky.,
The immediate problem before us may likewise best be solved without resorting to the “negligence” terminology. If a structure, even though permanent, can be changed, repaired or remedied at reasonable expense to abate the nuisance, then the condition is temporary. City of Ashland v. Kittle, Ky.,
There is an explanation for the reference to “negligence” in our opinions on this *759 point. It was apparently assumed that if a nuisance was traceable to negligence in construction or operation, the condition could be corrected or eliminated at minimal or no cost at all, and therefore was temporary. Without deciding if this assumption is valid, the real issue does not involve the existence or nonexistence of negligence as such. It involves simply the reasonable remediability of the condition.
To recapitulate, in determining whether a nuisance is permanent or temporary, the question is not whether the defendant failed to exercise due care in the construction, maintenance or operation of a structure. It is whether the cause of the nuisance results from some improper installation or method of operation which can be remedied at reasonable expense. If so, the nuisance is a temporary one and a plaintiff’s claim is not barred by the statute of limitations.
Appellants’ coal tipple was erected in 1951. In 1952 certain dust suppression equipment (costing $10,000 to $15,000) was installed. The plant was a permanent structure. If the nuisance created by it was a permanent one (dating from 1952), appel-lees’ claims were barred. If it was a temporary one which caused recurring injuries, appellees could file suit at any time (with their recovery being limited to damages caused within five years preceding the date of suit). Fergerson v. Utilities Elkhorn Coal Co., Ky.,
There was evidence that an excessive amount of coal dust was cast into the atmosphere from appellants’ plant. There was testimony of appellants’ own witness tending to prove the dust suppression equipment was not adequate to handle appellants’ coal loading operations. There was evidence that an improper method of operation impaired the efficiency of the dust collector. The proof was of sufficient substance to support a finding that appellants installed inadequate equipment and/or its agents improperly operated it. There was no evidence that this condition could not be remedied by reasonable measures at reasonable expense. The jury finding that appellants were negligent in the operation of their plant effectively determined that this could be done, and consequently the nuisance was a temporary one.
In view of the nature of the jury’s finding, we believe it will be clarifying to comment on the method by which this lawsuit was practiced. The plaintiffs’ complaint alleged negligence. The parties tried the case as if that was a real issue on the question of liability. The instructions likewise submitted the case on this theory.
As we have heretofore pointed out, the question of
negligence
was not a proper issue in the case for any purpose. The real issues (other than the amount of damages) were (1) whether appellants so maintained or operated their coal tipple that plaintiffs’ properties were unreasonably subjected to substantial damage, and (2) if so, whether the nuisance so created was a temporary or a permanent one. The last question became an issue in the case (although it had a bearing on the measure of damages) only because appellants pleaded the statute of limitations. This was an affirmative defense and the burden was on them to prove that the nuisance, if any, was permanent and plaintiffs’ claims were therefore barred. CR 8.03. City of Covington v. McKinney,
Where the pertinent facts are not in dispute, the validity of the defense of the statute of limitations can and should be determined by the court as a matter of law. Carr v. Texas Eastern Transmission Corporation, Ky.,
Appellants’ final contention is that there was a failure of proof of damages properly allowable on claims of this sort. Appellees’ evidence was directed to the difference in the market value of their respective properties before and after the injuries complained of.
Here again we find a failure to observe the distinction between a temporary and a permanent nuisance. As our cases consistently point out, the measure of damages is different. City of Hazard v. Eversole,
In order to avoid the statute of limitations it was necessary for appellees to establish a temporary nuisance, as opposed to a permanent one, and this we have held they did. Their proof on damages should therefore have been directed to the proper measure in such cases. Their evidence on this issue, however, related to the difference in market values of the properties involved before and after they were injured or damaged. This was not the proper measure and appellants consistently questioned it on their motions for a directed verdict and objections to the instructions.
We are forced to the conclusion that because appellees failed to prove damages recoverable by reason of the existence of a temporary nuisance, the trial court should have directed a verdict for appellants, and not having done so, their motion for judgment notwithstanding the verdict should have been sustained.
The judgment is reversed with directions to enter judgment for appellants.
