This is a prosecution commenced in the municipal court upon a complaint charging that on November 20, 1967, defendant deposited petroleum products into state waters, in violation of Fish and Game Code section 5650.

The municipal court sustained a demurrer to the complaint and dismissed the case. On the People’s appeal, the appellate department of the superior court reversed, Pursuant to rule 63, California Rules of Court, the appellate department certified the ease to the Court of Appeal, which ordered a transfer to settle an important question of law, that is, whether the Dickey Water Pollution Act, Water Code sections 13000-13080, has so far superseded Pish and Game Code section 5650 as to preclude any criminal prosecution for the act charged. After reviewing the matter we conclude that the appellate department correctly decided that the complaint states a public offense which is subject to criminal prosecution under section 5650.

The Dickey Act provides that the State Water Resources Control Board shall formulate and adopt a statewide policy for control of water pollution (Wat. Code, §13022). Nine regional water quality control boards are created (§§13040, 13041), with authority to prescribe requirements relative to a particular condition of pollution (§ 13053) and issue cease and desist orders against persons who cause pollution (§ 13060). Upon failure of any person to comply with such cease and desist order the board making the order may call upon the district attorney to petition the superior court for the issuance of an injunction restraining the violation (§13063).

At the time the Dickey Act was enacted (1949) section 481.5 (now § 5651) was added to the Pish and Game Code. This section, in substance, provides that whenever the Department of Pish and Game determines that a continuing and chronic condition of pollution exists, it shall report that condition to the appropriate regional water quality control board “and shall cooperate with and act through such board in obtaining correction in accordance with any laws administered by such board for control of practices for sewage and industrial waste disposal. ”

The complaint filed in the municipal court against defendant simply charges a violation of section 5650 of the Pish and Game Code, in the statutory language. In order to bring before the municipal court some additional facts which defendant contends are material, the parties entered into a stipulation that certain facts therein stated would be considered in ruling upon defendant’s demurrer as if they appeared on the face of the complaint or were subject to judicial notice. The additional facts were in substance these:

(1) Defendant operates a petroleum refinery which discharges into the Los Angeles inner harbor waste water containing a residuary product of petroleum.

(2) In compliance with Water Code section 13054, a regional water quality control board has established requirements with respect to the quality of defendant’s waste water.

(3) The continuing and chronic condition of defendant’s usual daily waste water discharge was the condition of the waste water discharged on November 20, 1967, the date of the alleged offense.

(4) The Department of Pish and Game requested the water board to take action against defendant under the provisions of Water Code section 13060 on the ground defendant’s discharge constituted a chronic condition of pollution. That request was “taken under consideration” by the water board.

The ground upon which the municipal court sustained the demurrer and dismissed the case is that the facts stated do not constitute an offense (see Pen. Code, § 1004, subd. 4). The complaint as originally drawn, stating the offense in the words of the statute, was sufficient to withstand demurrer (see Pen. Code, § 952). The question now is whether the facts added by the stipulation establish as a matter of law that no violation of Pish and Game Code section 5650 could have been committed. Stated differently, if there is any possible state of facts which would constitute a violation and which is consistent with the additional facts set forth in the stipulation, the demurrer lacked merit. In order to uphold the dismissal, it is and must be defendant’s position that these additional facts establish a complete defense to any alleged violation of section 5650 by it on November 20,1967.

It should be noted that the stipulation does not state that defendant has complied or attempted to comply with the requirements of the regional board with respect to the quality of defendant’s waste water. The implication is that there is at least a dispute on this subject, for the stipulation includes the statement that the department has asked the regional board to issue a cease and desist order under Water Code section 13060. We do not have before us any question as to what defenses, if any, might be available to defendant if it were to show that it had complied with the requirements of the regional water quality control board.

Three circumstances, taken together, are persuasive:

In People v. New Penn Mines, Inc. (1963) 212 Cal.App.2d 667 [ 28 Cal.Rptr. 337 ] it was decided that the Attorney General could not maintain a civil action to enjoin water pollution without proceeding under the Dickey Act. The appellate court concluded that the common law powers of the Attorney General in this field had been replaced by a statutory procedure. There is nothing in the reasoning or holding of that case to support the defendant’s argument here that the penal statute upon this subject has been repealed or made inapplicable to those guilty of chronic pollution.

Third: In three formal published opinions the Attorney General has ruled that Pish and Game Code section 5650 continues to be applicable to chronic as well as occasional offenders. ( 33 Ops.Cal.Atty.Gen. 77 (1959); 42 Ops.Cal.Atty.Gen. 53 (1963); 48 Ops.Cal.Atty.Gen. 23 , 29 (1966).) This interpretation is entitled to great weight, and the lapse of time since the first announcement of that view supports the inference that if it were contrary to legislative intent, some corrective measure would have been adopted. (See Meyer v. Board of Trustees (1961) 195 Cal.App.2d 420, 431-432 [ 15 Cal.Rptr. 717 ].)

We find unpersuasive the authorities cited by defendant which hold that in some other situations and in other jurisdictions administrative regulation has been held to supersede criminal prosecution. The California Legislature might have so provided when it adopted the Dickey Act, but it did not. Nor is defendant’s cause here aided by Harbors and Navigation Code section 151, which was enacted by the 1968 Legislature, providing for civil penalties to be imposed upon a person who intentionally or negligently causes oil to be deposited in the waters of the state. That new statute provides an additional weapon against those who pollute harbor waters, but without eliminating the means otherwise provided by law.

In arguing that it is exempt from criminal prosecution, defendant emphasizes the fact that its discharge of pollutants into the harbor waters is a chronic condition. This is the foundation of its argument that a cease and desist order under the Dickey Act (which is designed especially for chronic violators) is the only remedy the state has. Defendant’s interpretation would mean that criminal prosecution is reserved for the occasional violator, but immunity is conferred upon one who continuously, wilfully and inexcusably dumps any quantity of pollutants into the waters of this state. We cannot find that to be the legislative intent. Whether defendant is guilty or not should be determined in a trial.

The judgment of dismissal is reversed.

Jefferson, J., and Wapner, J. pro tern., concurred.

Respondent’s petition for a hearing by the Supreme Court was denied February 19, 1969. Mosk, J., did not participate therein.

Fish and Game Code section 5650; "It is unlawful to deposit in, permit to pass into, or place where it can pass into the waters of this State any of the following: (a) Any petroleum, acid, coal or oil tar, lampblack, aniline, asphalt, bitumen, or residuary product of petroleum, or carbonaceous material or substance. ...” Fisli and Game Code section 12000 makes a violation of this section a misdemeanor, punishable by fine or imprisonment in the county jail. (See §§ 12002, 12010.) A complete copy of these “discharge requirements’’ is attached to the stipulation as an exhibit. The document, which is headed ' ‘ additional permit conditions, ’ ’ contains only a list of nine specific prohibitions and a requirement that the “permittee” agree to reimburse the city for the cost of clearing or repair of the harbor facilities which may be made necessary by its use. Nowhere is there any express authorization to deposit petroleum or petroleum products in the water. Assigned by the Chairman of the Judicial Council.
