Cal. PRC § 6211

(a) Whenever a parcel of timbered land under the jurisdiction of the commission is totally surrounded by, or is contiguous to, a national forest or a state forest, the commission may, if it is in the best interests of the state to do so, and after 10 days’ prior notice to the Secretary of the Resources Agency for the receipt of comments, provide for the harvesting of timber from that land at the same time as the orderly harvesting of the surrounding or adjacent federal-owned or state-owned timber is conducted. In carrying out this section, the commission may enter into agreements with the United States or the Department of Forestry and Fire Protection for the inclusion of timbered lands under the jurisdiction of the commission within a total parcel to be offered for timber harvesting contracts.

(b) Notwithstanding any other provision of law, timber from lands under the jurisdiction of the commission shall not be sold to any California division of a primary manufacturer, or to any person for resale to a primary manufacturer, who does either of the following:

(1) Uses that timber at any plant not located within the United States, unless it is sawn on four sides to dimensions not greater than 4 inches by 12 inches.

(2) Within one year prior to the bid date and one year after the termination of the contract, sells unprocessed timber which is harvested from private timberlands and is exported into foreign commerce. For the purposes of this section, “unprocessed timber” has the same meaning as set forth in subdivision (d) of Section 4650.1.

(c) Any purchaser of timber from lands under the jurisdiction of the commission who makes use of the timber in violation of paragraph (1) of subdivision (b) is prohibited from making any further purchases of timber from any such lands for a period of five years.

(d) The commission may adopt appropriate regulations to prevent the substitution of timber from lands under its jurisdiction for timber exported from private timberlands.
