This is an appeal from a judgment in favor of plaintiffs, private landowners, granting damages and injunctive relief in an action for trespass and private nuisance against defendants who operate a cement plant. The evidence viewed in the light most favorablе to plaintiffs, who are aided by the verdict, shows the following.
In 1959 plaintiffs purchased their property in a residential/recreational area of LaPine. In 1970, after husband retired, they built a home there and began using the property as their residence. One of the plaintiffs’ purposes in moving to LaPine was the clean air. In 1976 defendants constructed the LaPine Readi-Mix Plant about 180 feet north of plaintiffs’ house in an area zoned M-2 Industrial. To the north of defendants’ plant lies a pole mill where bark is peeled from log poles. 1
In 1978 defendants added a cement storage silo to their plant. After the silo was constructed defendants began to receive large shipments of dry cement rather than the bagged cement they previously used. The dry cement shipments arrive about every 10 days by tractor-trailer. Delivеries are often at night. The dry cement is blown into the silo from the trailer. As it is blown in, clouds of cement dust permeate the air. This dust is so thick that one cannot see the outline of trees in the area. During the pumping process, vibrators shake the cement down inside the silo. If this process fails, a jack hammer is used to pound on the sides of the silo to pack the cement. The unloading process is very noisy. It takes about two hours to unload a trailer.
The plant begins its operations around 7:00 a.m. but has been known to start as early as 4:00 a.m. Usually five truсkloads of ready-mix concrete are carried out of the plant each day. Trucks loaded with *704 gravel also make deliveries to the plant. The gravel is dumped onto the ground and then is loaded into the cement trucks to be mixed with the cement and water.
These various trucks all pass directly by plaintiffs’ residence, raising dust which blows into plaintiffs’ home. The defendants generally do not water the access road until after 5:30 in the evening when the delivery trucks are washed out. The Department of Environmental Quality contacted defendants after plaintiffs lodged a complaint and cautioned defendants to water more frequently.
Plaintiffs’ first count in trespass complained that the cement dust, road dust, noise pollution and diesel fumes emanating from defendants’ readi-mix plant interfered with the exclusive possession of their land. They also complained that defendants’ use of their property unreasonably interfered with the use and enjoyment of plaintiffs’ property and created a private nuisance. In addition to diminished land values, plaintiffs sought damages for inconvenience, annoyance, physical discomfort and mental distress. They also sought injunctive relief.
The jury returned a verdict for $5,000 damages and the court, by way of injunction, required defendants to water the roadway and plant area traversed by motor vehicles to the еxtent necessary to control the dust, and enjoined defendants from operating the plant or receiving deliveries between the hours of 10:00 p.m. and 6:00 a.m. and all day on Sunday.
Defendants, in their first assignment of error, contend that there was no evidence of either intentionаl or negligent trespass and that their motion for directed verdict on Count I should have been granted. Where defendants appeal from the denial of a motion for directed verdict we review the evidence in the light most favorable to the plaintiffs.
City of Rogue River v. DeBoer,
*705
Deposit on a person’s land of airborne particles emanating from a neighboring plant has been held to be an invasion of that person’s right to the exclusive possession of land.
E.g., Reynolds Metals Company v. Martin,
337 F2d 780 (9th Cir 1964);
Renken v. Harvey Aluminum (Incorporated),
A trespass may arise from an intrusion upon plaintiffs’ land which is either intentional, negligent or the result of ultrahazardous conduct.
Martin v. Union Pacific Railroad, supra.
Intentional is used in this context to mean that the acts setting in motion the invasion were done with knowledge that a trespass would rеsult and not that the acts were done for the specific purpose of causing a trespass or injury.
Union Pacific Railroad Co. v. Vale, Oregon Irrigation Dist.,
*706 Defendants, in their second assignment, contend that their motion for directed verdict on plaintiffs’ count for private nuisance should have been granted.
To constitute an actionable private nuisance the defеndants’ interference with plaintiffs’ use and enjoyment of their land must be both substantial and unreasonable,
Jewett v. Deerhorn Enterprises, Inc.,
The cement plant produced clouds of dust which covered everything in sight, substantial noise at all hours, and noxious fumes. Defendants do not seriously contend that their interferenсe with plaintiffs’ use and enjoyment of their land was not substantial. Rather, they appear to argue that it was reasonable. They contend first that their invasion was not intentional. We have disposed of this argument above. In any event, as defendants recognize in their own brief, nuisаnce refers to the interest invaded and not to any type of culpable conduct.
Mikan v. Valley Publishing, Inc.,
Finally, defendants argue that the operation of their plant was reasonable as a matter of law because they had secured an air contaminant discharge permit from the Department of Environmental Quality and they had not been cited for violation of the fallout standards. Conformance with pollution standards does not preclude a suit in private nuisance, ORS 468.100(4);

Renken v. Harvey Aluminum (Incorporated), supra,
Looking to the guidelines set out in
Jewett v. Deerhorn Enterprises, Inc., supra,
*708 In assignment of error number three, defendants argue that their motion to strike plaintiffs’ allegations of inconvenience, annoyance, physical discomfort and mental distress should have been granted.
Distinct from or in addition to damages compensating plaintiffs for the diminution in property value as a result of a nuisance, it is proper to award consequential damages for discomfort, annoyance, inconvenience and personal injury.
Spencer Cr. Pol. Con. v. Org. Fertilizer,
In their fifth assignment of error, which we will consider here, defendants contend that plaintiff husband’s testimony concerning the worsening of his bronchitis and emphysema was inadmissible, and that the claims in plaintiffs’ complaint for husband’s illnesses should have been stricken. Defendants argue that the stаndard to establish whether a nuisance exists depends on whether the defendants’ use of their property would interfere with an ordinary, reasonable person’s use and enjoyment of his property,
Jewett v. Deerhorn Enterprises, Inc., supra; Amphitheaters, Inc. v. Portland Meadows,
What the defendants fail to realize is that once facts are introduced which could establish a nuisance based on an interference with a normal, reasonable person’s usе and enjoyment of land, a particularly susceptible plaintiff may recover for physical discomfort from the effects of that nuisance separately and distinctly from the damage to his property.
*709
Plaintiffs may also recover for mental anguish which is the direct rеsult of defendants’ trespass,
Douglas v. Humble Oil,
The question is one of the sufficiency of the proof that the anguish was caused by defendants’ trespass or the nuisance defendants created. Plaintiffs testified that they were very concerned over the loss in value of their home because they are retired and on a fixed income. They also were distressed because they had moved from the Willamette Valley to escape the air pollution only to have this purpose frustrated by defendants’ pollution of the area. Further, they testified that they suffered anguish in not being able to be out of doors and enjoy their yard and flowers. Finally, they were agitated over the potential health hazard of continually breathing the dust-laden air. Any anguish plaintiffs suffered is causally linked to their concern ovеr the affects of defendants’ trespass and the resulting nuisance. The allegation of emotional distress, annoyance, inconvenience and aggravation of husband’s illness was properly submitted to the jury.
In the fourth assignment of error defendants contend that the court erred in failing to strike plaintiffs’ allegation concerning diminution in the value of their real estate because there was no proof of damage.
Plaintiff wife testified that their residence was worth "at least $50,000” if the readi-mix plant was not *710 in operation. She then testified that with thе readimix plant there the property was worth $10,000.
The Supreme Court has held that an owner of property is competent to give an opinion regarding its fair market value and diminution in value,
e.g., Searcy v. Bend Garage Company,
Finally, in assignment of error number six, defendants argue that the court erred in granting injunctive relief. Many of the arguments defendants raise are the same as those discussed under the second аssignment of error. There is evidence that defendants caused substantial harm to plaintiffs’ interest in the exclusive possession of their land and in its use and enjoyment. There is ample evidence to support a finding that defendants acted unreasonably in the sense that the hаrm to plaintiffs was greater than they should be required to bear.
*711 The injuction balanced the needs and interests of the parties. It did not close down defendants’ business. It only enjoined defendants from operating during nighttime hours and imposed the condition that defendants water the rоad to prevent excessive road dust. The injunction only restricts defendants from operating their plant at such times and in such a manner as would unreasonably interfere with plaintiffs’ use and enjoyment of their property.
Affirmed.
Notes
There is also a shake mill in the immediate area whiсh is no longer in operation.
The record shows that the dust was obvious to all the neighbors. When defendants were informed by plaintiffs of the effects of their business on plaintiffs’ property, wife was essentially told to "go to hell.”
ORS 468.100(4) provides:
"The provisions of this section are in addition to and nоt in substitution of any other civil or criminal enforcement provisions available to the commission or a regional authority. The provisions of this section shall not prevent the maintenance of actions for legal or equitable remedies relating to private оr public nuisances brought by any other person, or by the state on relation of any person without prior order of the commission.”
In addition, the defendants’ discharge permit states:
"G8. The issuance of this permit does not convey any property rights in either real or personal property, or any exclusive privileges, nor does it authorize any injury to private property or any invasion of personal rights, nor any infringement of Federal, State or local laws or regulations.”
